Prototype Machinist

Protoshop Machinist

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.

Karman Space & Defense provides concept-to-production solutions for mission-critical systems on spacecraft, launch vehicles, missiles, hypersonics, and integrated defense systems. We believe that solving the industry's most complex and mission-critical challenges requires relentless determination and a willingness to push the boundaries of possibility. Karman Space & Defense brings to bear unparalleled production capabilities, unmatched engineering expertise, and unflinching analysis to render the impossible, possible.
