About OS3

Affordable, intelligent humanoid robots built to deploy at scale. Backed by Y Combinator.

About the role

We design and build our robots in-house, from structural parts to exterior covers, and iterate on them continuously as the robots run in the real world. You'll own the CAD design of robot parts and enclosures — working remotely, with your designs printed, machined, and tested on real robots in our San Francisco lab.

What they're looking for

  • Strong CAD fundamentals — parametric modeling, assemblies, tolerancing, DFM
  • Hands-on prototyping experience: you've printed, machined, assembled, and fixed your own designs
  • A feel for designing around electronics, cabling, and moving joints
  • Clear async communication — you can drive a design loop remotely
  • Nice to have:
  • Experience with robot arms, grippers, or mobile platforms

  • Design robot parts, enclosures, and covers in CAD for 3D printing, CNC, and sheet metal
  • Package cameras, sensors, compute, actuators, and wiring into clean, serviceable assemblies
  • Own designs from concept through prototype, assembly feedback, and revision
  • Produce CAD geometry clean enough to feed our simulation and testing pipeline
  • Iterate fast: you design remotely, we build in SF, and you get feedback from real robots within days
