About the role

Descriptionhttps://comma.ai/jobs#cnc-machinist-head-of-prototyping.We are comma.ai. We’re a small team building the Android of self-driving cars. Our fleet drives hundreds of millions of miles every year all around the world. We build openpilot, an open-source driving agent, and comma four, the hardware that runs it. openpilot and our hardware are designed and built in San Diego. We’re looking for someone to join our hardware team and run our new machine shop. You’ll lead prototype manufacturing for all future comma products, from comma four-style devices to our new datacenter products. We’re building Send Cut Send at home. The shop already has a Haas VF-2, a lathe, 3D printers, and budget for whatever else we need to bring prototyping fully in-house. You’ll own parts from CAD to finished prototype: CAM, setup, fixturing, machining, inspection, and iteration with the hardware team. You’ll turn ambiguous ideas, sketches, and early designs into working parts fast.
Qualifications: Experience with CAM, CNC setup, and machining Excellent attention to detail Resourceful enough to take ambiguous designs from sketch to working prototype Haas CNC experience is a plus Mechanical engineering and CAD skills are a plus
How to apply: Email work@comma.ai with examples of cool projects you've built.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
