Production Machinist (Manufacturing)

AI data centers, industrial electrification, remote operations that need megawatts yesterday and can't wait for utilities to catch up.

American Turbines is designing small modular gas turbines, purpose-built for distributed power generation. Machines designed from a blank sheet to be manufactured at scale, clustered in arrays, and dispatched in minutes. Hundreds of units operating in parallel, dynamically matching load like a compute cluster matches demand. We are a seed-stage company backed by the investors behind SpaceX, Boom Supersonic, and Hadrian.

The Machinist will be the person who turns engineering models into finished hardware. You will run the 5-axis, own setups from raw stock to inspected part, and put the first prototype components in the hands of the build team.

You will work directly with the design engineers to make sure parts are machinable, tolerances are achievable, and the geometry coming off the machine matches the model. You will program and operate 5-axis CNC mills and lathes, set up fixturing for complex aerospace-grade components, and manage the full workflow from stock prep through finishing and inspection. You will flag tolerance stack-ups, suggest geometry changes that cut cycle time, and push back on drawings that do not pencil. Skilled machinist with deep experience operating and programming 5-axis CNC mills, plus comfort on lathes and 3-axis equipment. Proficiency with CAM software (Mastercam, Fusion 360 CAM, NX CAM, or equivalent) and hand-edited G-code. Strong background machining aerospace parts: nickel superalloys (Inconel, Hastelloy), titanium, and stainless. Experience with turbomachinery, aerospace, or motorsport hardware is a strong plus. You have built prototype parts in a fast-moving shop and know the difference between a production environment and an engineering environment.
