Project Debug raises, sorts by sex, and releases millions of (non-biting) male mosquitoes in Singapore to reduce the local mosquito population and prevent the spread of dengue and other mosquito-borne illnesses. Our trial in Fresno, CA showed a 95% reduction in female mosquitoes during the seasonal peak.

Our engineering team is pretty small and we need a solid generalist engineer who is interested in becoming a domain expert in our factory, where we do automated rearing and sex sorting. If you run a homelab, have tinkered with Arduino, and can prompt/write some Python, we can teach you everything you need to know about our stack (Go, Python, React, Kubernetes, Tensorflow).

Reach out to katejm@debugproject.com and please mention HN in your email.

I am intrigued by products like these which gives "hands-on" a new meaning. Being a new farmer-engineer, this is the kind of work I would love to do.

Somewhat limited applicant pool with it being based in Singapore sadly.

Also, debug.com is a killer domain name, I'd love to hear how you got hold of that one.

Stack: TypeScript, NestJS + Fastify, React, Valkey, PostgreSQL, Docker, Kubernetes, Terraform, AWS.

We ship OSS self-hosted and have a live cloud SaaS: https://betterdb.com/login In the last two months we've averaged more than one release per week across multiple products and channels. That's what "moves fast" looks like in practice. We recently started moving more and more into the LLM cache space via both observability and actual libraries.

We hired our first engineer in March and are looking to expand the team — no pressure on timeline, we'd rather find the right person.

Just email kristiyan@betterdb.com with a bit about yourself and why this is interesting to you. I reply to everyone. It might take a day or two given volume, but you'll hear back.

Recover is building the infrastructure for all restoration work, streamlining how remediation contractors run jobs while we handle the red tape and headaches. Recover is a platform born from insurance requirements, financial ledgers, spatial intelligence; built to collapse hundreds of messy painpoints into a single flow.

We've just closed our seed round, live desktop and IOS app and are ramping up to convert demo offices to live deployments and rolling out to 50+ waitlisted offices. We're sprinting fast to cover the last features in V1 roadmap including subcontractor portal and insurance disputes workflows and one-click materials marketplace.

We're hiring for a specific type of engineer:

PM-minded engineer for messy domains. The rare hybrid who can sit across from an insurance adjuster, a franchisee, and a senior estimator in the same day, walk away with the actual workflow in their head, and collapse a scattered process into a single screen the technician actually wants to open. Owns the full loop: stakeholder interview → spec doc → spreadsheet model → prototype → production. Equal parts taste, insight, and stamina. Ships features that flow smoothly and improve how work gets done.

Company: We’re building a geologic modelling software, based on reasoning, to help mining and mineral exploration companies work faster. Our goal is to create a way to enable open-ended, interpretive geologic problem solving to be done programmatically, changing the way to explore for hard rock and critical minerals. Currently in active fundraising.

Role: You are the founding engineer on the team, joining co-founder (Neil, CEO) and myself (Jeff, CTO) as first employee. You’ll have a deep influence over systems and architecture. You will have ownership through the entire stack from the database, through geostatistical backend services, through 3D rendering on the client side.

Work rooted in agentic systems, so an understanding of the internals of things like Claude Code, and a broader understanding of orchestrating agents to complete complex discrete tasks is important.

You:

- Fluent in Typescript, Python, and framework/tooling agnostic (Currently using things like NextJS, Supabase, Cesium)

- Eager to learn about mining domain knowledge around the software.

- Ownership of the codebase, and the systems that support the software (project management, CI/CD, monitoring, etc.)

- Open to doing a yearly month abroad with Neil and I. Last year, it was Oaxaca, Mexico.

Apply: Shoot me an email at jeff@deepcoretech.com with a resume, and a short blurb about yourself. If you include a 1 minute video/Loom, I'd love to see it. Must be eligible to work in Canada without a VISA requirement. We are located in Squamish, BC.

We make Architect: a Kubernetes runtime that hibernates idle pods in place and wakes them in 50ms with TCP connections intact. Five engineers. You'd be the 6th.

If tracing an x86 instruction in the morning and hunting a control-plane race in the afternoon both sound fun, and you insist on measuring rather than guessing, this is the job.

Customers run Architect for workloads where cold starts hurt: real-time voice & video AI agents, long-warming JVM apps, stateful data services that can't be rescheduled cheaply. 1.0 shipped Q1 2026; you'd join mid-way through 2.0. Seed-stage, VC-funded, a few years of runway. Fully distributed across the Americas and Europe.

What you'd work on:

- Hibernation surface: containerd shims and CRUISE, our Zig-native CRIU replacement.

- Control plane: per-node DaemonSet streaming checkpoints; admission controller resizing hibernated pods in place.

- Networking and migration: eBPF/XDP at line rate; cross-node live migration to production; cross-cloud next.

You're a senior generalist. Years across the stack: assembly to frontends, hardware-near, comfortable in x86. Tests ship with the code, decisions get worked out in writing, and you measure rather than guess. Strong in Go; willing to use Zig, Rust, or C.

Bonus: eBPF/XDP, CRIU, Linux kernel internals, containerd, gVisor, live migration, or public writing in kernel/container/eBPF land. Strong systems depth and the willingness to pick up the rest is enough on its own.

Apply: https://loopholelabs.io/careers - we respond within the week (typically a few days).

Form is an AI fluency/integration startup for executives & their teams. We build AI applications tailored to how clients work, and need an engineer to do the building.

A typical engagement starts with a client describing a workflow eating their week. You scope alongside them, then build something that makes it disappear. Stack is whatever fits: TypeScript and Python, React or Next.js, Claude and other LLM APIs, integrations with the SaaS our clients use (Notion, Slack, Google Workspace). RAG, agents, prompt engineering, and evals when the work calls for them, not for show.

We're looking for someone who has shipped end-to-end as an early engineer somewhere small, has real opinions about LLM applications, and writes readable code. Comfort scoping with clients and communicating in writing is essential, since most of our work happens that way.

1099 fractional, paid monthly. 10-20 hrs/week, $75-150/hour. 40-hour monthly minimum, scaling with client demand. Potential to convert to a full-time role ($150k-$220k) as the practice grows.

Remote, Austin/US-based. To apply: https://formai.build/jobs or email jobs@formai.build.

We're building a system that represents domain knowledge as modular probabilistic models — making analysis rigorous and transparent. Users can connect these models flexibly into larger structures. The system enforces consistency across them, and propagates uncertainty through each step. Our first applications are in finance and scientific research, with use cases ranging from equity valuation and distress monitoring, to particle physics.

We’re building out our team in the following areas:

* Product Software Engineering (Quantitative Modeling)

* Program Synthesis Engineering

* Applied Category Theory Research

* Bayesian Software Engineering

* Finance Operations (Accounting, Analytics & Workforce)

We're also looking for Domain Experts to collaborate on high-value use cases -- identifying and validating opportunities, shaping them into working solutions with our engineers, and taking them from pilot to production with real users. Practitioners with expertise in Valuation Models, Quantitative Default-Probability Models, or Interest Rate Prediction Models are particularly relevant right now.

We’re on a mission to radically transform the way we design and construct our built environment.

Backed by Lightspeed Venture Partners, Eagle acquires civil, structural, and MEP engineering firms and transforms them with applied AI. Our thesis: 85% of what engineers do is automatable, yet less than 5% has been touched by AI; the largest gap of any profession. By arming designers with frontier technology, our ambition is to build the most valuable, talent-dense engineering firm in the United States.

We're looking for our first members of technical staff. If you get excited about building from zero, get energized by direct access to users, and want to work in a problem domain that's barely been touched by AI, we'd love to talk.

Acrylic Robotics is a creative tech company focused on changing how people design and create art. We build software that learns a person's taste in art, ML design tools that turn it into a concept, and robots that create the concept with paint on canvas, so original artwork can be commissioned at a price most people can actually afford.

We're hiring an ML lead to own the model side. The system has to take a user's intent and references, turn them into concepts the user can refine through feedback, and produce the brushwork-level instructions our robots paint. This would be the first dedicated ML hire on the team; they'll help set the technical direction, ship the first real end-to-end version, and build out the team behind them.

We're based in Montreal, QC, but open to a hybrid position for the right person. Please email me at walker@acrylicrobotics.ca or look at https://acrylicrobotics.ca for more info.

Electrical and mechanical engineering consulting firm in Waterloo, serving the Canadian building construction industry — a market that's still mostly designed the old way. I designed the original platform schema and UX vision; my early code attempts got abandoned when running and growing the firm took priority. The years since have been spent figuring out how to scale this properly and fill those gaps. We're now at the depth and size to support a real build — with no committee in the way, and with my time properly committed to it this time. I'm hiring an exceptional software engineer to take it to the production platform it was always meant to be.

Real users, direct collaboration with the founder, and 20 years of MEP practice plus the platform vision. Few founders building automation in this space bring both.

Profitable, bootstrapped, 18 years old. Equity is earned, not granted — a real cut of a real business, not options in something that may or may not happen.

Stack: TypeScript, React, Tailwind, shadcn/ui, AG Grid, TanStack Query, Drizzle, PostgreSQL, Python (FastAPI), Node.js, Docker.

Looking for: full-stack, agentic-first as a daily working mode, shipper not writer.

I'm Nick, CTO & co-founder. We're Rippling, but for insurance carriers paying their sales force. Every policy sold triggers a chain of payouts across brokers, agents, and sub-agents. Today that runs on spreadsheets and legacy vendor systems and tomorrow they'll run on Chestnut. Nationwide and other major carriers have already made the switch.

Revenue is up 8x in the last year. We're backed by a16z. Founding team came out of leadership at Ethos (insuretech that recently IPO'd in January).

The work is state-heavy and correctness-critical: payouts that must reconcile with finance to the cent, dynamic agent hierarchies, retries, chargebacks, partial failures. These systems move real money and cannot drift.

You'll design schemas, build backend logic, ship UI, deploy, and own the sharp edges that show up with real enterprise customers.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS. We use AI aggressively and expect you to as well.

We're looking for 3–6 years on real product systems. You're thoughtful about invariants and failure modes.

We're a seed stage (VC backend) company building a vertically integrated design and manufacturing platform for precision mechanical parts. We are developing our own CAD/CAM software running on top of our own manufacturing facility. The team has previously developed CAD kernels, design software, and autonomous robotic manipulators, and comes from Amazon Robotics, Siemens, nTop, and Vicarious Surgical.

Most design and manufacturing software companies treat the factory as a black box and optimize geometry in isolation. Our bet is that the only way to really bring software and ML into design and manufacturing is to own the full process ourselves. The platform you'd help build includes: customer-facing design software, the ML engine that turns CAD files into machine instructions (G-code), the simulation layer, and the shop floor operations themselves.

We are looking for someone independently driven who wants to operate like a founder. You'd own architecture, help shape the company's vision, and build a product from the ground up. If you've worked on cloud infrastructure, distributed systems, CAD/CAM software dev, geometry kernels, robotic perception, motion control, or spent time on a shop floor, we'd like to talk. We are open to sponsoring visas for the right candidate.

Roles:

Founding Computational Geometry Engineer: Hybrid B-rep + SDF kernel work. STEP AP242 ingestion, B-rep surgery, feature recognition, and the geometry layer underneath our DFM and CAM pipelines. If you've worked on Parasolid, OCCT, nTop, or shipped anything that touches BRep diff, parametric replay, or differentiable geometry, we want to talk. C++ and Python.

Founding Full-Stack Engineer: Someone who can take ownership of the reliability, automation, and evolution of our core systems that tie into our CAD/CAM software, internal shop-floor systems. You’ll work across the stack, with a strong emphasis on backend, infrastructure, and system-level engineering, to strengthen the foundations that everything else runs on. This role is for someone who enjoys digging into complex systems, building the architecture and tooling to keep them running reliably (including the frontend).

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.

Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.

We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.

In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B. We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~500). Now we’re scaling the platform.

We have PMF, and it's time to scale! For more and to apply, see https://smarterdx.com/careers

Hi, Alex and Jeremy here from UMH.

8 years ago, Jeremy was absolutely frustrated with the status quo of data infrastructure in manufacturing. Companies paid millions per year for "shitty 90s software" and are still doing that today, when there is much better software out there for open-source. So we decided that we can do this better, first founded a System Integrator, realized most of the tasks in setting up and maintaining a data infrastructure can be standardized, and decided to found the currently VC-backed UMH, which is built on open source software and is open source itself.

What we're actually building: We build and scale a real-time data platform that runs hundreds of Benthos pipelines inside a single Docker container (UMH Core), processing millions of industrial messages that control actual production processes.

Plus a local-first user interface (Management Console) where both non-technical factory workers and power-users/developers can work together. And yes, we care about UI in enterprise/industrial software.

We're at an inflection point: proven product-market fit, scaling fast, and greenfield work ahead that will serve tens of thousands of users. Engineers here own problems end-to-end — from talking to veterinarians about their biggest frustrations, to shipping production code, to iterating based on real feedback.

How True is this? Have you hired anyone before with experience but that didn't have a lot of python experience? I've mostly worked in node, but I've done a little with python and could start some django courses this weekend if you're actually giving people shots here.

We've tried to be flexible historically but found that we really need folks who are fluent in Python because our skills tests all use Python and we need devs to hit the ground running on day 1 and all our projects are in Python.

I did recently hire a dev whose Python is a bit rusty but who made it through the skills tests. But, for the most part, devs without solid and recent Python experience aren't getting through our skills tests.

Octozi is a revenue-generating seed-stage company building AI agents for clinical development workflows. Bringing a drug to market can take a decade and cost up to $2B, keeping treatments expensive and delaying life-saving therapies for the patients who need them. We're cutting the cost and time of these workflows while improving the science and analysis of clinical data.

We already have commercial contracts with multiple pharma companies and are scaling the team to meet demand. The interesting problems span agent orchestration over messy clinical datasets, human-in-the-loop review at scale, and turning unstructured medical reasoning into auditable, regulator-ready output.

Looking for a full-stack engineer to join as a founding hire with startup experience strongly preferred. Stack: Python, TypeScript, AWS, PyTorch.

Reach out to careers [at] octozi.com and mention HN.

We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients, who trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100, with software engineering backgrounds and who are still coding. Notable recent projects include internal tools for Anduril, and the original buildout (both auction site and operations infrastructure) of Voltage Park. This is a remote-first agency, but some projects involve onsite work.

I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership.

Applicants must meet a high bar - I personally review every hire. In return you’ll get:

  * Flexibility and a low-bureaucracy environment
  * Clients that won’t treat the vendor like “the B Team”
  * The chance to act as a code architect, not just implement tickets
  * Exposure to a wide variety of industries and modern challenges
  * Me as your personal champion and advocate

We’re currently especially seeking:

Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)

Our Tier 3 ("mid-tier") roles are typically 5-10 years experience with $150-$180K total annual comp.

Our Tier 4 ("senior") roles are 11-20 years experience, $215-$260K total annual comp.

(Higher tiers exist, and we always welcome exceptional applications.)

Though not yet universal, many of our clients are now demanding senior/staff engineers with success using modern agentic approaches. Be ready to explain where current models work well and where they do not.

Please apply using this Google Form: https://forms.gle/7yv5jhybsGRNDx3o9

I'm very interested in this position but living in Europe, is there any chance I could still apply for this?

Thanks.

Hey, I'm one of Stellar's founders. We're building AI for large contact centers, our primary product is voice.

Contact centers are the last place where companies actually talk to their customers. We listen to calls every week and it's fascinating. AI here helps real people: shorter wait times, 24/7 support, lower cost. We’ve helped companies go from 60 to 98% pickup rate in weeks. We’ve had (human) agents asking us to accelerate our roll out plan because the days with Stellar are so much better than the days without.

We’re all builders. Everybody in our company still writes code. We have one role open:

We are looking for implementation leads that love working with clients. FDEs welcome as well.

This role is perfect if you:

* Want massive ownership at a small team

* Actually enjoy solving hard problems (real-time audio at enterprise scale)

* Think making AI sound human in niche dialects is a fun challenge

We're looking for a Senior Software Engineer to help maintain and build automation around our Azure Verified Modules offering in the short-term, but with the long-term goal of transitioning to work across all our core products. You will act as a lead for new features and functionality, as well as providing mentorship to junior colleagues.

I'm Ryan, an EM and engineer here at YC. We have a small, 18-person software team with no PMs -- engineers own everything end-to-end.

We build the software behind YC's $6B in investments: tools that help partners evaluate thousands of startups per batch, AI-powered apps that founders use every day, and platforms like Work at a Startup that connect candidates with YC companies. Engineers get unlimited AI tokens -- both for development and to build AI-powered products. What wouldn't you build to help founders + YC with that much firepower?

What makes this different from other roles:

* You'd learn more about startups here than you could possibly imagine. Every batch brings hundreds of founders building things across every industry, and you're right in the middle of it.

* We attend Demo Day, founder dinners, and work directly with partners and many of the companies. (They make great products!)

* We pay well, offer carry in the fund (like equity), and provide generous relocation support if you're not in SF yet.

Two roles open:

* Product Engineer -- full-stack, own the product lifecycle. Rails/React stack. Build tools that power how YC invests in and supports startups. It's a wide range, and sometimes it feels like labs-like work, other times it feels like a supersuit to power founders and our Partners like Garry and Jared.

* Community Builder and Software Engineer -- hybrid role. Run YC's talent-facing programs (meetups, tech talks, career expos) AND build the software that makes them scale. You need to be a great engineer and LOVE to build and support communities.

We're also exploring a Technical Chief of Staff role to work with one of our GPs -- someone who can think analytically, drive operations, and scale what they do with software.

Checkout more about the roles, and email me directly if you're excited to learn more about startups than you will anywhere else - ryan@ycombinator.com

We're a 4-person boutique consulting shop in Albany, NY building custom web apps for healthcare, legal, and education clients. Looking for a senior engineer to work alongside the founder on production systems for clients.

Stack: Go (Echo, ENT), PostgreSQL, AWS, Cloudflare, Clerk, Alpine.js, Tailwind, Vite, Terraform. We have a proprietary ~1M-line Platform Foundation that anchors most projects.

You: Shipped real Go in production (not "willing to learn"). Comfortable across the stack. Opinions about migrations, RBAC, and not-overengineering. English fluent enough to talk directly with clients.

Process: Paid trial task → 3-month contract → conversion to long-term contractor. No middlemen, no platform markup.

Apply: hiring@yidisconsulting.com with a Go project you're proud of and a brief note on how you'd approach a vertical-slice task touching ENT, an Echo handler, and an Alpine component.

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* our CTO is the founder and still writes code

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

MintMCP helps enterprises safely roll out agents to the entire organization (e.g, governance around MCP tools and agents like Claude Code / Codex / Cowork). We're building an MCP gateway with abstractions useful for 1) preventing agents from doing the unintentionally bad things you hear about every week without constraining them to be useless, 2) getting the rest of your teams and organizations to adopt them with minimal friction.

We're a small team of humans with dozens of agents: our company operates on the infrastructure we build for enterprises. We're looking for agent-forward engineers and GTM folks to help solve scaling problems, maintain the highest standards for security, make agents and MCPs usable and useful.

If you have experience in infra, security, and agents, and believe MCP, while not perfect, will evolve to become critical AI infrastructure, you might find the problems we're working on exciting!

By uniting applied AI research, flexible infrastructure, and seamless developer tooling, we enable companies operating at the frontier of AI to bring cutting-edge models into production.

Apply Here: https://jobs.ashbyhq.com/baseten?utm_source=gkzEP29VD4 or email Jason.dupree@baseten.co

We are hiring for multiple core roles:

1. Solution Architect: You will partner closely with sales and customers to translate business needs into technical solutions, run technical discovery, and guide repeatable deployments and proofs of value for customers. This role is a great fit for entrepreneurial, customer-facing technical professionals who want a front-row view into how modern companies adopt AI at scale, and who enjoy working across technical discovery, solution design, demos, deployment scoping, and hands-on customer implementations, in close partnerships with Sales and Engineering

2. AI Solutions Engineer/Forward Deployed Engineer: You will partner directly with customers to architect, build, and deploy high-scale production AI applications on Baseten’s platform. You’ll own the journey with customers from initial exploration to production deployment. To be clear, this is a technical engineering role with hands-on coding and software dev that also includes aspects of product management, technical customer success and pre-sales solutions engineering mixed in. We’re language agnostic but strong Python and ML experience is a big plus.

The Offer:

Compensation: Very competitive, we’re looking for folks with a breadth of experience

Equity: This is an opportunity to participate in the ownership of a fast-growing AI Infrastructure platform

Location: We are based out of San Francisco with offices in New York. We are also open to remote employees for these roles.

Process: If you’re interested, please apply here https://jobs.ashbyhq.com/baseten?utm_source=gkzEP29VD4 or email me direct at Jason.dupree@baseten.co

We are building the trust stack for AI code generation, targeted at high-stakes computing where wrong numbers cost real money: a statically typed functional language designed for coding models, a compiler whose guarantees double as audit-grade trust infrastructure, and a coding model fine-tuned on the language with compiler fitness as the training signal. Language and model are co-designed.

Small team out of PyTorch, FAIR, and Meta. Strong institutional VC support from our pre-seed; active investor interest heading into seed.

Founding Research Scientist: own the agenda across the language and the model. Type system design, compiler analyses that produce useful fitness gradients, and fine-tuning open-weight coding models on a language with no pretraining footprint. Publish in PL and ML venues. Strongest fits cross between machine learning, programming languages, and formal methods. PhD preferred, equivalent output equally fine. Stack is Rust, Lean 4, Python.

Founding Engineering Lead: own engineering across compiler internals, language runtime, GPU backends, notebook and library tooling, and the AI infrastructure around training, evaluation, model release, and likely public inference. We already support x86 and ARM, CUDA and AMD, macOS and Linux, and the matrix grows. Real feel for statically typed functional programming expected; the kind of engineer who picks up Lean or Haskell on a weekend because they wanted to. Have led engineering before, formally or not. Stack is mostly Rust with Python where it earns its place, primarily on AWS.

Both roles: comfortable with early-stage ambiguity, define your own roadmap, defend it with evidence.

Psiphon is a VPN app used by millions of people to access the open internet in regions where it's restricted. Small team, software that matters.

We're building the next-gen client app in Flutter (iOS, Android, macOS, Windows) and need someone who can work across both iOS native and Flutter. Split is roughly 65% Flutter, 35% iOS native (Swift, StoreKit, entitlements, network extensions). You'll have mentorship from a senior iOS specialist for the deeper networking work.

Day to day: Feature development in Flutter, iOS platform integration (subscriptions, permissions, App Store), and occasionally going deep into network extensions and packet tunnel providers. Small team (~3-4 core devs), high ownership, low ceremony.

Looking for: Strong Swift experience beyond just UIKit/SwiftUI app dev, comfort with the iOS ecosystem (App Store process, provisioning, StoreKit), and willingness to context-switch between Swift and Dart in the same day. Flutter experience is a strong plus but not required if you pick up frameworks quickly.

Contact: jobs@psiphon.ca

We’re building an Agentic AI Security Platform that helps teams secure autonomous AI workflows. We’re looking for a senior engineer to help design and ship core systems across policy enforcement, runtime monitoring, incident workflows, and auditability.

You’ll work across backend and product surfaces: Rust + gRPC services, GraphQL APIs, and TypeScript/React interfaces for security operations. You should be comfortable owning features end-to-end, making pragmatic architecture decisions, and collaborating closely with product/security teams in a small, fast-moving environment.

Strong fit if you have experience with distributed systems, secure-by-default engineering, and production observability. Security product background is a plus, but not required if you’re excited to learn quickly and build in this space.

If this sounds interesting, email us at [hello@lineation.ai] with Resume/CV plus links to your GitHub/LinkedIn and a short note on systems you’ve built.

We're hiring a junior dev who is genuinely AI-native — your primary tool is Claude Code or Cursor, not your own typing. You'll extend our agentic AI copilot embedded in Architect AI, our portfolio-management web app: text-to-SQL over financial schemas (holdings, transactions, performance), RAG over our internal docs, action tools, deploy and operate the system on Linux + Docker.

Stack: Python/FastAPI, LangGraph, LangSmith, React/TS, SQL Server, Qdrant, Redis, Anthropic + OpenAI + Azure AI.

Required: real SQL chops, ability to read Python and judge AI-generated code, a public project we can look at where you actually used Claude Code / Cursor / Copilot to ship something. 0–2 years professional experience. Recent grads welcome. You'll report directly to the Director of PM who built the system.

Opendate is the operating system for live music venues — booking, ticketing, marketing, and settlement, all in one place. We replace the tangle of spreadsheets, holds-and-confirms email chains, and ticketing platforms that independent venues, promoters, and festivals have been duct-taping together for decades. Customers range from 200-cap clubs to multi-day festivals.

We're a Rails shop with real backend problems: multi-tenant ticketing at on-sale scale, financial settlements that have to reconcile to the penny, and integrations with the rest of the music industry's plumbing (Stripe, Dwolla, Seats.io, Twilio, SendGrid). If you like systems where correctness actually matters and the users are people you can go meet at a show, you'll fit in.

Stack: Rails, React/Redux, PostgreSQL, Redis, BigQuery, AWS, GCP, Docker, Terraform. Flutter on mobile. AI-first engineering culture — Cursor, Claude Code, and Copilot are part of the daily workflow, not banned from it.

100% remote within the US (no sponsorship), with optional Indianapolis or Chicago offices if you want them. Looking for 5+ years of senior full-stack experience, comfortable owning projects end-to-end and shipping to production weekly.

We have our roots in tech entrepreneurship (Jan Beckers), and this mindset still dominates our work culture, even as a regulated financial institution. We are a team of ~40 with a flat hierarchy, hands-on leadership, fast-paced decisions, and a little nerdy culture as people are actually passionate about their work. Stack: AWS, Databricks/Spark, Python, PostgreSQL, Agentic AI.

If the complexity of financial markets excites you as much as the complexity of distributed systems, you'll love it here. Competitive comp, relocation & visa support, stellar team.

entex is a small established Swiss IT service provider. We offer some of the classics: IT support, infrastructure, web development and high-end security cameras. We deal with a lot of “boring” tech and it’s great! (Well, mostly great!)

After a recent change in ownership, we are looking to grow, reinforce the existing team and expand our service offering.

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.

Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.

Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.

We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.

We're hiring an AI Engineer to build and ship production AI systems - not research prototypes. Startup experience is a must: we want someone who has shipped fast in a small team, owned systems end-to-end, and is comfortable with ambiguity. Big-company-only resumes won't be a fit.

You will own: - RAG pipelines and agentic workflows (end-to-end accuracy) - GPU-optimized model deployment (Trident-style architecture) - Production MLOps: distillation, fine-tuning, training orchestration - Data modeling for AI persona capabilities - The infra around it: Docker, CI/CD, logging, monitoring, observability

You should have: - 3-12 years shipping AI/ML in production (notebooks do not count) - Time at a startup or scale-up where you owned what you built - Strong Python; bonus for C++/Java/C# in performance-critical paths - Hands-on with RAG, MLOps tooling, and GPU deployment at scale

W2 full-time. Must be authorized to work in the US. No remote, no C2C.

Return (https://return.energy) is hiring a DevOps engineer who will build and run the infrastructure behind platforms that accelerate the transition to carbon-free energy. Return's main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.

While we employ over 120 people, Return's technical team is still small (15 people). Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service. Behind it sits a mix of EU cloud and on-site compute at our battery sites, with strict uptime and security requirements.

During the first four years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced DevOps engineer who can own the full picture: cloud environments, self-hosted infrastructure at our BESS sites, and the operations centers in Amsterdam and Eindhoven from which we run the fleet.

Your primary focus will be to design, automate, and operate the infrastructure that our virtual battery platform runs on. That means EU-only cloud providers for application workloads, hardened on-premise setups at our sites, and the connectivity in between. You will be the person who decides what gets deployed where, and who makes sure it stays up and stays secure.
