We're a company doing real operational work in e-commerce/3PL logistics. AI usage internally is still basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows in production yet. That's what this role is for. You'd be the first dedicated AI engineer here. Two things at once: ship agentic workflows that replace real manual work, and build the underlying platform (APIs, MCP tools, docs) so other teams can build their own instead of asking you for everything forever. First project: an agent that reads an inbound invoice question, pulls the correct (often complex) invoice, and drafts a context-aware reply a teammate can review and send. Currently ~1 hour of manual work, target is ~30 seconds. What we need:
3+ years SWE, 1-2+ of which building production AI systems (not prototypes) 10+ agentic/LLM workflows shipped end-to-end — not toy demos Evidence you've built infra/tools for other people to use, not just yourself Strong Python and/or TypeScript Some background in e-commerce, 3PL, logistics, or comparable B2B ops
Nice to have: RAG, vector DBs, multi-step orchestration, eval frameworks, heavy Cursor/Claude Code/Copilot usage. Fully remote, direct access to leadership, real scope to define how AI gets built here rather than inheriting someone else's stack.

Looking for a strong Python engineer to build AI features end to end, from rapid prototype to production and the evaluation that keeps them honest. Join the engineering of 22 and company of almost 100 located all over the world. Note, AI experience is a plus, but not required.
Stack: Python (FastAPI), Langchain, Postgres, Redis, Qdrant, GCP, K8.

Lumen (https://lumenresearch.ai) is building the cognitive layer for physical AI. Most robotics efforts today learn from thousands of hours of human teleoperation; we think that has a ceiling. White paper: http://lumenresearch.co/paper
Team of two ex-founders — you'd be #3. Pre-seed, runway well into 2027, raising a seed later this year.
We test many model architectures against many sims, and hooking them together is our biggest pain point. We use Gymnasium and Shimmy as the plumbing and upstream useful pieces as open-source contributions. You'd build per-sim adapters to a shared interface contract, bridge single-env vs. GPU-vectorized and sync vs. async paradigms, and own our eval harness.
Looking for: strong Python, Gymnasium (especially the vector API), hands-on experience with Isaac, MuJoCo, or Gazebo, and a track record of getting models running in sims where they didn't before.
Email hi@lumenresearch.co about you and your projects — link one where you got a model working in a sim it wasn't built for and you'll jump the pile.

AI usage today is basic — decks, spreadsheets, a few people vibe-coding dashboards. No real agentic workflows yet. This is a founding seat to build that: shipping high-impact agentic workflows yourself, plus reusable building blocks (APIs, MCP tools, docs) so any team can build their own.
Example first project: an agent for inbound invoice questions — reads the question, pulls the right invoice, drafts a context-aware reply — turning an hour of manual work into ~30 seconds.
Need: 3+ yrs SWE with 1-2+ yrs shipping production AI systems, 10+ real agentic/LLM workflows built end-to-end, a genuine platform mindset (built tools/infra for others, not just yourself), strong Python and/or TypeScript, and relevant sector background (e-commerce, 3PL, logistics, or similar B2B).
Nice to have: RAG pipelines, vector DBs, multi-step agent orchestration, eval frameworks.

We manage over $3B for CPG brands like OLIPOP, Tropicana, and Dr. Squatch. We 5x'ed revenue last year and are on track to 4x this year.
The role is engineering + customer implementation: working closely with customers that are household names to run their implementations to ground, as well as enable the broader set of customers.
Stack is Rails, Python, TypeScript, Postgres, and AWS.
Job Description: https://jobs.ashbyhq.com/confido/e3d42ff2-4ab4-4469-9091-d24...
We build AI agents that run real operations. Humans talk to our agents to run commercial real estate: leases, contractors, invoicing, accounting. We're live in production across several European jurisdictions, with real customers and real money.
We need a Forward Deployed Engineer to own a client-facing use case end to end: a strong backend engineer who is also the face of the team to the customer.
The job:
- Talk to clients directly and often. Pull requirements out of messy conversations, explain tradeoffs, own the relationship
- Turn jurisdiction-specific lease rules, tax and accounting mappings, client-specific workflows into tools our agents call
- Ship to production in your first month, then keep it alive
What we need, in this order:
1. Self-driven, real ownership. You'll have a lot of freedom and support, but the use case is yours end to end - nobody will be feeding you tickets.
2. Excellent English and real customer-facing experience. You'll be on client calls every week.
3. Serious backend experience. You've shipped and operated production systems, and can work as the only engineer in the room. We use AI tools heavily, but we don't vibe code: your engineering judgment and review are what make the code shippable, and you own what you merge.
4. LLM agents in production, or you ramp fast: tool calling, evals, knowing when a plain deterministic tool beats a model call.
Bonus, not required: containers and CI/CD, RBAC and auditing, LangChain/LangGraph, operator or consulting background.
We're a small senior team across Europe and South America. For this role we need you in Europe.
Competitive comp - we have no salary bands, for the right person we'll stretch.
Apply: mercedes@kinxshn.com, subject "HN - Forward Deployed Engineer", salary expectation and CV attached - skip the skills inventory: tell us about something hard you shipped and a customer you made happy.

We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be strong in most of these areas: web application security, relational database design (PostgreSQL query plans, indexes, and constraints, not whatever the ORM emits), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect race conditions.
A note on how we work: we think deeply about the systems we build, and we believe understanding comes from doing the work yourself, not from handing it to a model. If you ship code you don't understand, we're genuinely not a fit, and that's fine. If that paragraph made you nod, we want to hear from you.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll work with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.

We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients 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: we’re still coding. Notable recent projects include a gigantic ERP migration for Anduril Industries, and a skunkworks with Surge Labs helping to develop some of the frontier LLM models themselves (yes, seriously). 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 Feel free to submit, even if you already did in the past.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)
Tier 3 roles are typically 5-10 years experience with $150-$180K total comp.
Tier 4 roles are 11-20 years experience, $215-$260K total 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.

Dashdoc is a SaaS Transport Management System for road freight. We help carriers and shippers run transport operations on one shared platform.
We’re hiring a product-minded engineer to help us expand in Belgium and the Netherlands. Local specifics: e-CMR mandates, digital waste regulations, Dutch/Flemish accounting standards, regional carrier workflows often block deals or deployments. Your job is to find those blockers and turn them into shipped product.
You’ll work directly with customers, sales, CSMs, and product. You’ll be able to spend time with carriers in Belgium and the Netherlands, watch users use the product, read contracts/regulations, then spec, build, deploy, and measure the features yourself.
Stack: React, React Native, Python/Django, Django REST Framework, PostgreSQL, Google Cloud. We use Shape Up, ship continuously, and use AI coding tools like Claude Code, Cursor, and Codex.
Good fit if you speak Dutch fluently, write clearly in English, like owning ambiguous product problems end-to-end, care about simple UX and clean code, and enjoy deleting code as much as adding it.
Apply: https://dashdoc.welcomekit.co/companies/dashdoc/jobs/product...

We secure the SaaS apps companies actually run on: M365, Salesforce, and hundreds more. You’d be on the Threat product team working full-stack. That means browser extension code (content/background scripts, manifest v3, message passing), backend services chewing through millions of events, and the data pipelines feeding our detection engine. One day you’re in TypeScript debugging why a content script won’t capture form submissions on some vendor’s weird SPA. The next you’re in Python fixing a Kafka consumer that’s falling behind. Sometimes you’re in Rust optimizing a hot path in the telemetry collector.
Big current focus is shadow AI, i.e. catching when employees paste sensitive data into ChatGPT, Claude, or whatever LLM showed up this week. You’d build the systems that detect it.
Looking for ~8+ yrs experience, real browser knowledge (DOM, event loop, SPA routing, CORS, not just “I used React”), prior browser extension work, strong TypeScript, comfortable in Python, willing to write Rust, plus data-at-scale chops (event streaming, Postgres, Elasticsearch, Kafka). Bonus: AI security (prompt injection, exfiltration), detection engineering/SIEM, or security tooling.

Nexvia is a modern real estate agency. I bet you were not expecting to read this on Hacker News ;-)
We are an hybrid company, with an old fashion business and revenue stream that enables us to be self funded and make our own choices. At the same time, we are using software to enhance our users', customers' and advisers' experience. We view technology as a way to empower people and try to deploy it in that direction.
Part of our business is also to sell software to banks (SaaS).
All our software has been and is being built internally. We are small (22, mostly customer facing) so we pick our battles.
We work with PHP Laravel and React for the core of our web applications. We also use Python (for infrastructure management, build tools, data processing and secondary applications) and AWS.
Cool things:
* your work is making common people's life easier * Fluid interaction with everyone (small company) * Stable management and good work environment (people turnover is extremly) * Contribution on our technology choices * Quality before vibe
Less cool things: not the best place to test the latest technology or do resume building.
Requirements:
* Be based and have the right to work in Europe * On site presence the first months is a minimum * Some first experience within a european culture (work experience or background) * Ability to write some code, we have technical tests during the interview process.
You can discover more and apply through our site https://www.nexvia.lu/jobs or find a way to contact me on my profile.

We're working in the AI for science space, specifically at the point of experimental execution. Scientific labs run on expensive instruments locked behind proprietary software with no real API. Getting an agent to actually operate these machines is unsolved, and it's the bottleneck between "AI can design experiments" and "AI can run them." That's what we're building.
Small, technical, well-funded team with real design partners already pulling on us. You'd be one of the first engineers, working directly with the founders across the stack: agents, low-level systems, ML infra, and the runtime that ties it together. Lots of hard, unglamorous, high-leverage problems.
You might be a good fit if:
- You're a strong generalist who's shipped real systems and can go deep when needed
- You're comfortable in messy, low-level territory
- Bonus: ML/agents, scientific instrumentation, or industrial automation
- You want high ownership, high pace, onsite in NYC
We're mostly a Python/Rust/Typescript shop. We care about what you've built, not credentials.
To apply, email contact@tetherline.dev with a bit about yourself and something you've built you're proud of.

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model.
We've been building since 2020, started in campaign security and data science, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are 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 an exciting opportunity for those who are interested in building systems and agents to solve hard and often adversarial problems.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). We’re looking for engineers with web scraping, data pipelines, or security tooling experience. Experience with Python/Django, Typescript, React, and LLM APIs is a plus. Must be authorized to work in the US.
Email steven@kanary.com with something you've built and why it was hard. Also be sure to include the keyword I’ve put in my HN profile.

We're a consumer fintech with 20M+ users who trust us to budget, save, invest, and bank in one place. Profitable for 4+ years. And as of today, our average employee tenure is 3.6 years, a number you almost never see in startup tech, and one we're quietly proud of. People stay because the work is good, the people are sharp, and we've built something worth staying for.
Now we're building net-new consumer products from zero, and we're looking for people who love to tinker and build stuff to ship them with us.
The kind of person we're looking for: • Top fraction of a percentile in craft, the kind of good that's hard to fake • Builds for fun, not just for work. The kind who ships a working prototype over the weekend and can't help themselves • Comfortable owning 0 to 1 consumer products end-to-end • Allergic to politics, theater, and bureaucracy
What you get: • Remote, anywhere with reasonable timezone overlap (and for someone truly exceptional, we'll make async work) • Real scale from day one (20M+ users, real money, real consequences) • Compensation that beats the market. We pay well and we mean it. Base, discretionary year-end bonus, meaningful 401(k) match, and meaningful equity in a profitable, growing unicorn (the kind that's actually worth something) • Platinum PPO health benefits with Blue Shield, top of the top of the line, covering your entire family • A mission worth your time: make money simple, so people spend less time managing it and keep more of it • Small senior-heavy teams, direct ownership, no layers • Forthcoming with the business metrics that matter, so you always know how the company is actually doing • The startup perks done right: catered lunches, wellness stipend, team offsites, casual dress. The stuff that compounds when you're showing up engaged for years, not months • Profitable for 4+ years, so you build with conviction, not runway anxiety
Stack: python, claude, postgres, react.js /react native

ABOUT FRACTILE Fractile was founded in 2022 on the bet that, eventually, the world’s most capable AI systems would be limited in their impact by the amount of time they take to produce useful outputs. We bet everything on the logical conclusion: that the only way to truly unlock this latent value, to make speed viable at scale, was to radically re-invent the hardware that we run our frontier AI models on. Ever since, we have been building chips and systems that tackle this problem: how to generate output at thousands of tokens per second, while handling the complexity and capacity challenges of operating large models at very long contexts.
We’ve recently raised $220M from Founders Fund and Accel and the most important work lies ahead. Come and join the mission!
THE ROLE As a Software Engineer you will be a core part of our technical team working alongside the hardware, software and research teams to solve cutting-edge problems in AI hardware, ranging from verification to simulation, alongside the best of the best (DeepMind, Apple, Meta…).
ABOUT YOU 1) You have exceptional ability. We look for pivotal IC contributions that solved the hardest problems in big tech companies or hedge funds; competitive hackathons, International Olympiad medals, or rank highly in other competitions like advent of code
2. You are a top engineer. We are not looking for specific languages or technologies - you will be a master of several, you excel at algorithmic skills and solving problems logically in any programming language. And you are very comfortable learning new skills on the fly. You like to work in Python and C++
3. It’s likely you have several years of professional experience, but we will make exceptions for the right candidate
4. You want to work with the best. And you are excited to work in chips, solving the hardest problems at the frontier of AI
WHAT WE OFFER 1. Competitive compensation and meaningful equity 2. A very cool office with London's best views 3. Private medical insurance and pension benefits

Home-based care should be the default in American healthcare. It isn't, mostly because the technology has never been good enough. Patients heal faster at home, it costs a fraction of facility-based care, and it's what people actually want — yet the industry runs on phone calls, spreadsheets, and systems built in the 90s. We started Axle Health because we think that's fixable, and because the stakes are high enough that it's worth doing right.
We're Axle Health, and we think in-home care deserves world-class technology. We're building the operating system for home-based healthcare — the scheduling intelligence, the clinician tools, the logistics coordination — everything that has to work perfectly so a clinician shows up at the right door at the right time with everything they need. It's a hard and important problem, and we're just getting started.
The complexity is real: real-time scheduling optimization across dynamic clinician networks, last-mile logistics that make Uber Dispatch look simple, integrations with every flavor of EMR and payer system you've never heard of, mobile-first tools that have to work in spotty cell coverage in someone's living room, and the compliance surface area that comes with handling PHI at scale — we need to build it all, and we want people who think this stuff is genuinely fun.
Currently hiring Senior Software Engineers (7+ YOE) for:
Backend (Python + Django): https://www.axlehealth.com/careers?ashby_jid=8db08b55-399c-4...
Interoperability (Typescript + Node): https://www.axlehealth.com/careers?ashby_jid=0bcdc195-ac3f-4...

Ecosmic is on a mission to reduce threat exposure in space by building software for Space Situational Awareness. To achieve this, we built a team of flight dynamics engineers and computer scientists to build & package in-house algorithms into easy-to-use, reliable, and secure products. As an example, our platform recently allowed us to identify a series of close approaches in GEO involving Russia's Luch/Olymp-2 and a Western telecommunications satellite, possibly attributed to SIGINT activity.
We're hiring a Senior DevOps Engineer (mid-level candidates are welcome too!) to aid the effort of unlocking on-premises deployments of our algorithms with Kubernetes, and to contribute to the evolution of our platform.
Our stack includes Python for backend services and high-level algorithm tooling, C++ for performance-critical components, AWS for cloud infrastructure, and Terraform for IaC. We currently use managed serverless services, and we’re beginning a gradual migration from C++ to Rust for its reliability guarantees.
You’d join a team of three software engineers who love working in such a fantastic domain. I currently take care of most of the infrastructure work with the team, and we’re looking for someone who can help us tackle this new challenge.

I'm Ketan, Head of Engineering at Credo. We're a seed-stage, HIPAA-compliant health-tech company fixing one of healthcare's dumbest problems: getting the right patient data to the people who need it. Billions of pages of medical records still move by fax every year — causing care delays, admin overload, and dangerous gaps in what providers know. Our AI platform gets clinicians the patient answers they need fast. We have paying customers using it daily.
This is an early engineering hire on our Platform team (5–7 people), reporting to me. You'll work the full stack, shape our architecture, and ship to real users every week. High ownership, lots of surface area, frequent collaboration with our ML team.
Stack: Python/Django, Postgres, Vue, Temporal (for our patient-ingestion pipeline and long-running workflows), Google Cloud, and a mix of AI models (mostly Gemini + OpenAI). No prior Temporal experience needed, just enthusiasm for it.
How we work: strong code-review and pairing culture, serious about testing, async-first with a single daily sync, and we've fully integrated plan/spec-based AI tooling into our workflow (Claude, Cursor, CodeRabbit, Copilot — your choice).
Looking for 3–5+ yrs full-stack experience, solid Python + a backend framework, comfort with relational DBs, a modern JS framework, real testing chops, and someone who thrives with ambiguity and owns problems end to end. Healthcare/FHIR/HL7 and AI-feature experience are nice-to-haves, not requirements. Must be in/near NYC for the weekly in-person day.

Happy to answer questions in the thread!

* Turning ambiguous problems into production systems. * Owning outcomes, not tickets. * Working across product, architecture, and implementation. * Reviewing and improving AI-generated code. * Shipping quickly without creating a maintenance disaster.
Requirements:
* Strong Python, TypeScript, or equivalent experience. * Strong engineering judgment. * Strong communication skills. * US residency.
