Job description

Founding Research Engineer – 3D Geometry & Machine Learning

Get AI-powered advice on this job and more exclusive features.

FitX is rebuilding, with AI, the foundation for how footwear is created, made, and experienced.

We’re not here to compete with the big brands — we’re here to reinvent the system they’re built on.

Where You Come In

With our seed round closing in September, we offer a competitive package with meaningful founding-level equity — plus the opportunity to define the core systems of a company set to reshape an industry. The infrastructure you build here will set the benchmark others follow for years to come.

We’ve previously scaled companies from napkin sketch to market leadership, backed by investors like Kleiner Perkins and Warburg Pincus. Now we’re applying that same playbook to a harder, deeper problem.

The Role

Lead the creation of a 3D geometry + machine learning engine that transforms raw, chaotic geometry into flawless, manufacturable reality — a problem no one else has solved at scale. The systems you build will become the invisible engine driving breakthroughs across FitX — shaping what’s possible far beyond geometry itself.

This is your territory: you find creative ways to build, push the boundaries of what’s possible, and carve the path from first principles.

Your first challenge: Rapidly deliver an ML-augmented pipeline that turns raw, noisy, incomplete consumer scans into watertight, manufacturing-ready geometry - high throughput, fully automated, and CAD/CAM ready.

What You Bring

Deep expertise in 3D geometry and ML for shape processing — whether in medical imaging, robotics, AR/VR, or related domains
Proven ability to work from raw, imperfect 3D data toward manufacturable outputs
Familiarity with techniques such as point-cloud registration, geometric deep learning, topology repair, and surface reconstruction
Rapid learning and comfort applying research ideas to uncharted, real-world problems
A founder’s mindset: proactive, self-directed, and motivated to build what’s never been built before
