Prototype Machinist (3:00pm to 11:30pm)
Job Description
Prototype Machinist (3:00 PM – 11:30 PM)\n
Atomic Machines – Emeryville, CA
Pay: $45–$55 per hour
Shift: Swing Shift | Full-Time
Location: Emeryville, California
\n
Company Overview\n
Atomic Machines is pioneering a new era of micromanufacturing with its revolutionary Matter Compiler™ technology — a groundbreaking platform that transforms digital designs into fully functional micromachines. By enabling processes and materials that conventional semiconductor manufacturing cannot support, Atomic Machines is unlocking new capabilities in MEMS, micro-mechanical systems, and advanced device manufacturing.
\n
With facilities in Emeryville and Santa Clara, Atomic Machines sits at the intersection of precision CNC machining, automation, metrology, and cutting-edge R&D hardware development.
\n
About the Role\n
This Prototype Machinist (Swing Shift) role begins on a standard 8:30 AM – 5:00 PM schedule for onboarding and training. After ramp-up, it transitions to a permanent 3:00 PM – 11:30 PM shift.
\n
You will take full ownership of machining projects from concept to completion — including CAM programming, tooling selection, fixturing, CNC machining, inspection, and documentation. Your work directly supports the development and refinement of the Matter Compiler™ and Atomic Machines’ next-generation micromanufacturing capabilities.
