## Job description

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.
