We’re creating robots that autonomously construct buildings. We design all of our hardware and software in-house in central Amsterdam, starting with autonomous bricklaying robots.
Building a robot like this means solving all sorts of interesting challenges: figuring out the robot's position with sub-mm precision; navigating autonomously around the building site; automating measurement and calibration of new robots; lots of distributed systems and so on.
Our robots are now continuously deployed on customer sites and we are earning real money as a masonry contractor. The full team is more than 50 people and we're growing rapidly to meet demand.
Our stack is mostly: Rust, TypeScript, Python, NixOS.
Some open roles:
- Software Engineer, Controls
- Software Engineer, Machine Vision
- Assembly/manufacturing technicians and robot operators

P.S. We're always on the lookout for very strong generalist engineers who can operate at any layer of the stack (firmware, networking, UI, application code - whatever's needed!) Drop me an email if this sounds like you.
Other's are welcome to correct me though, if it's off.
How much is language a barrier for these kinds of jobs? I'm a native speaker of English and think that I can become proficient with French again within 3-6 months of immersion.

We're looking for a backend-leaning fullstack dev. You will be the first engineer outside of the founding team. Here is a bit more about us:
We're a seed stage AI startup backed by several top tier VCs.
We're on a mission to ensure patients get the coverage they deserve and providers get paid fairly! To do so, we're debugging core problems in the US healthcare system with a modern tech stack and AI. We use AWS, K8s, React, and Rust but there is no requirement to have prior experience with them specifically. We'll teach you!
We are a founding team made up of ex-YC, Amazon, Meta, and Harvard Business School with previous successful exits. We also have a 6+ month customer waitlist!
We're hiring our first engineer outside the founders. You'll work directly with customers to understand their needs, design the right solution, and build from zero to one. You'll own entire parts of the roadmap and tech stack while wearing multiple hats. Most important characteristics are resilience, work ethic, and curiosity. We care about slope, not where you are today. This is an opportunity to work in an insanely fast paced, high ownership environment while solving real problems in healthcare.
We're happy to share more details on the role in person/on zoom. Please fill out this form if interested!
We value quality in engineering at Langfuse: We try to find elegant solutions to complex engineering challenges, and we invested significant effort in enhancing our production setup (infra as code, top observability setup and more).
If you'd love shipping in open source, writing about what you work on and working hard with super interesting and sophisticated customers (devs) - reach out!

Are you a great coder (Python/Typescript, but great skills are transferrable), who enjoys close collaboration with end-users in solving their hard problems?
Do you have a solid foundation in the AI/LLM-world - or are you a great at the above and willing to learn?
Are you well versed in data engineering concepts, and excited to work with the latest GenAI models and bring these solutions into production? Then I'd love to hear from you!
We are a small team who care deeply about our work as well as each other. We iterate fast, and err on the side of showing a quick prototype of an idea, rather than spending hours in meetings talking about it.
Our vision for this project is extremely ambitious, and you will be a crucial part of making this a reality. We've been expanding the team, and are currently looking to fill a few extra roles in the UK/EU-timezones.
If you fit the above description, hit me up at jakob.hoppermann@abbvie.com with your resume + a little bit about yourself!

Layer Health is an AI/ML startup (fresh Series A) leveraging LLM’s to transform how clinical data is understood and used. We’re tackling a huge inefficiency in healthcare—patient chart abstraction, a $2B/year problem. Today, nurses handle it manually, drowning in notes and reports instead of focusing on patient care. Chart abstraction represents the largest source of labeled data in healthcare; an ML/researcher’s dream for answering complex clinical questions (which his why much of our team has a deeply focused research/ML background).
Work Locations: Boston /Back Bay (beautiful office overlooking Boston Common) or NYC (Grand Central area). No remote work
Headcount: ~18; likely 40-50 by end of year

I might be interested, but would need to "commute" from Portland Maine, so it's an important distinction :)
