SAEKI - Manufacturing at software speed

Europe's defense industrial base cannot respond at the speed modern conflict requires. Legacy suppliers operate on month-long timelines. Tribal knowledge is retiring. Supply chains are fragile. SAEKI is building the operating system for autonomous factories - the infrastructure that lets Europe manufacture mission-critical components at software speed.

The Role

As a Junior Computational Geometry Engineer, you work on the geometry core of our Manufacturing Intelligence stack: the engine that takes an arbitrary customer CAD model, reasons about how to build it, and then proves that we built it right.
You start on well-scoped parts of that engine, next to the engineers who built it, and grow into owning them. Your code runs in the factory.

What We're Looking For

• Foundations. Degree in computer science, mathematics, mechanical engineering or a related field, with real depth in geometry, linear algebra and numerics. Internships, thesis work or serious side projects count. We do not expect years of production experience.
• B-rep Basics. You are comfortable with topology, NURBS, meshes and point clouds. You may never have shipped a robust boolean, and you still understand why floating-point robustness destroys naive implementations, and you want to learn how the field handles it.
• Kernel Exposure. You have worked with a geometry kernel and mesh libraries in at least one project: OpenCASCADE, CGAL, libigl, Open3D, PCL, Parasolid or comparable.
• Technical Ability. Solid modern C++ (17+) plus Python for tooling and rapid iteration. Rust is welcome. You write code others can read, test and maintain.
• Manufacturing Curiosity. You want to understand what happens once geometry meets a spindle, a nozzle or a fixture. CNC, additive or metrology exposure is a bonus, never a requirement.
• First Principles Thinker. You reason by physics and mathematics, not analogy. When an algorithm fails on a real part, you dig until you know whether the bug sits in the code, the model or the assumption.
• Learning Speed. You take direct feedback, apply it immediately, and close your own knowledge gaps without waiting to be taught.
• Industrial Grit. You want to stand next to the machine in Germany and watch your output run. The feedback loop between your code and cutting metal is the point.
• On-site. Ability to work in person at our HQ in Zurich, Switzerland.

What we're not looking for

• Researchers who want to publish and hand off. You ship.
• CAD users. This is a role for people who build the tools, not drive them.
• Engineers who need a clean spec. The problem is defined by the part, the machine, and the customer - you'll help define it.
• People who treat “it works on the test model” as done. Real customer CAD is broken, degenerate, and adversarial. That is the job.
• Engineers who are uncomfortable with ambiguity or rapidly changing priorities.

What we offer

• Mission: Rebuild the industrial sovereignty of the West. Your work directly enables production of mission-critical hardware for defense and space.
• Total Ownership: High-stakes autonomy in your domain. You own both the problems and the solutions - and have the authority to execute.
• The Environment: Access to a 8,000 m² state-of-the-art facility featuring 5-axis CNCs, industrial robots, and industrial 3D printers. Your algorithms run on real hardware from day one.
• The Team: "Special Forces" model. Everyone senior, everyone ships. No politics, no bureaucracy. Direct feedback, high standards.
• Compensation: Competitive salary + meaningful equity.
• Location: Zurich HQ, with occasional time at Factory ONE in Munich.

Apply

• Resume: Focus on the geometry work you have actually done. Thesis, internships, projects, coursework.
• GitHub/Portfolio: Show us the hardest problem you have solved. Code, a write-up, or a part that came off a machine because of you.
• Coverletter: Why this mission? Why now? What would you build first?
