You love geometry, maths and code that runs close to the machine. Invent the CAD and toolpath systems behind next-generation hardware.

A young Toronto company combines manufacturing with software: it writes its own CAD and geometry tools and makes advanced parts for leading tech companies, including projects in aerospace, robotics and medical devices. Your first project: automatically matching and validating 3D CAD models against 2D drawings, a job someone still does by hand today. Next on the list: a geometry kernel of its own, a CAD setting built in-house, and the engine that plans CNC tool paths.

What you'll own

A core subsystem, end to end, until you know it better than anyone

Automated matching and validation of 3D models against 2D drawings

Foundational systems built from first principles, not libraries glued together

A small team covering software, firmware and mechanical engineering

Must-haves

Strong maths and computational-geometry fundamentals

You understand what happens close to the hardware (experience limited to web apps, without a strong maths base, won't fit)





You like problems with no set stack and no detailed specification

2+ years of experience; technical depth matters more than pedigree, and no PhD is needed

Working from the Toronto office five days a week, 9-9-5, commuting daily (no remote or hybrid)

Already allowed to work in Canada; sponsorship isn't available

Bonus points

Production code for geometry, CAD/CAM, graphics or tool paths

A background in GPUs, chips, embedded systems, firmware or self-driving vehicles

Results in maths olympiads, or research in geometry, graphics or robotics

What's in it for you

$250k–$300k USD base + 0.1–1% equity

Deep technical problems with real parts and real customers

Full ownership of a subsystem in a small, ambitious team

Good to know

Full-time, on-site in Toronto, 9-9-5

Process: half-hour call with both founders → one-hour technical interview → a take-home assignment only if needed → up to a week of paid work at the office with the team → offer
