Company Overview

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 .

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 .

About the Role

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.

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.

Key Responsibilities
