Build Engineer & Machinist

San Francisco, CA

About the Role

The Build Engineer & Machinist will be the person who turns engineering models into physical hardware. You will own the machine shop, run the CNC equipment, build the test rigs, and assemble the first prototypes with your own hands.

You will work directly with the design engineers to ensure parts are machinable, tolerances are achievable, and assemblies actually fit together. You will program and operate multi-axis CNC mills and lathes, set up fixturing for complex superalloy components, and manage the full workflow from raw stock to finished, inspected parts. When the team needs a test fixture by Friday, you will figure out how to make it happen.

You will also own the build process for prototype assemblies: rotor stacking, bearing installation, combustor integration, instrumentation routing. You will be the last set of hands on the hardware before it goes on the test stand.


What We’re Looking For

Skilled machinist with experience operating 3- to 5-axis CNC mills and lathes. Proficiency with CAM software (Mastercam, Fusion 360 CAM, or equivalent) and G-code programming. Experience machining nickel superalloys (Inconel, Hastelloy) and titanium is strongly preferred. Familiarity with GD&T, precision measurement tools (CMM, bore gauges, surface profilometry), and shop-floor quality processes.

You've built prototype hardware in a fast-moving environment and understand the difference between a production shop and an engineering shop. You're comfortable working from incomplete drawings, flagging design issues early, and improvising fixturing. Experience with turbomachinery, aerospace, or motorsport hardware is a strong plus.

U.S. person required (ITAR).

Compensation

$120,000 – $160,000 base. Generous stock package.
