Build the tools
engineers reach for.
We are a small team in Paris teaching machines to read and write geometry. Open a role below and apply from there; if none of them is yours, applications are open the year round at the bottom of this page. If you are looking for the product instead, try Fab; if your company wants to build something with us, work with us.
Open roles
Founding Geometry EngineerRethink the geometry layer under the agents: how they see a part, act on the kernel, and check the result.Paris · On site · Permanent
The job sits at the intersection of mechanical engineering, computational geometry, 3D software and AI: the geometry layer of our agent, and the CAD/CAM features of our own application.
You have spent five or more years building 3D or CAD software — geometry kernels, B-rep, meshes, solvers — on the hard problems of geometry, and you know enough mechanical engineering to read a drawing and judge whether a part makes sense.
AI EngineerBuild engineering agents and turn customer problems into products they can use.Paris · On site · Permanent
You work directly with industrial customers and own projects from understanding their workflows to delivering a product they can use. Build the agent harness, tools, evaluations and infrastructure, take responsibility for production reliability, and bring what you learn back into our core agent and product.
You have built systems with models and tools, show high agency and product judgment, and take end-to-end ownership. Experience with CAD/CAM or mechanical engineering is a major plus. Competitive salary and equity.
AI Research (Internship)Explore how models reason about geometry, and build the benchmarks that measure progress.Paris · On site · 4 to 6 months
You take a research question and carry it through experiments: a modality the agents cannot handle, a way to improve their geometric reasoning, or a benchmark that tells us something we did not know. You build the data and evaluation needed to compare approaches and understand where they fail.
A background in AI is required, with experience implementing and evaluating models. You should be comfortable turning a hypothesis into an experiment and explaining what the results show.
AI Engineer (Internship)Build engineering agents and deliver complete customer projects with the team.Paris · On site · 4 to 6 months · Spring 2027
You own a complete customer project, from understanding their workflow to building, evaluating and delivering a solution they can use. Work directly with industrial users, build the agent loop, tools and interface, and bring what you learn back into the product. The founders and engineers support you on scope, technical decisions and delivery.
You are comfortable building in Python, have built something with models and tools, and show initiative and a desire to take end-to-end ownership. Personal projects, coursework and open-source contributions count. Experience with CAD/CAM or mechanical engineering is a major plus. Competitive salary.
Mechanical Engineer (Internship)Real parts, real drawings, and the checks the agents are scored against.Paris · On site · 4 to 6 months
You build the ground truth the agents are measured on: parts and drawings from our design partners, the tolerances and process choices a machinist would make on them, and the checks that say whether an agent's result would survive the workshop. You run the agents on real work and tell us, in engineering terms, where they are wrong.
A background in mechanical engineering is required — a drawing has to be something you can read and judge.
None of these?
