Prototype Machinist

About the role

The Protoshop Machinist is responsible for end-to-end fabrication of prototypes and models, including programming, set-up, machining, and hands-on problem solving. This role requires creativity, adaptability, and strong communication skills to bridge the gap between engineering concepts and manufacturable parts. Unlike traditional machine shop operators, the Protoshop Machinist collaborates closely with cross-functional teams—often educating non-machinists on design-for-manufacturability and rapid prototyping best practices.
