Mechanical Design Engineer - Robot Parts & Enclosures (Contract)

Contract
Visa Sponsorship

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.

You will:

  • 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

You have:

  • 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
  • Industrial design sensibility for exterior covers and finishes
  • Option to convert to full-time. In-person interns are welcome to apply as well, provided they have CAD experience.
