Junior Computational Geometry Engineer in Zürich

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: Open CASCADE, 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.
