Prototype Machinist (3:00 PM – 11:30 PM)

Atomic Machines – Emeryville, CA
Pay:  $45–$55 per hour

Shift:  Swing Shift | Full-Time

Location:

Emeryville, California

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

Interpret  3D CAD models  and engineering drawings to plan setups and machining workflows.

Program CAM using  Fusion 360, Mastercam, Hyper Mill , or similar platforms.

Run a variety of CNC equipment, including:

3-axis, 3+2, and  5-axis CNC mills

Live-tool CNC lathes

Waterjets & laser cutters

Machine precision components with tolerances down to  ±0.0005" (±13 µm) .

Design and build custom  fixtures, tooling, and work holding  systems for prototype manufacturing.

Perform  in-process and final inspections  using calipers, micrometers, height gauges, and CMM.

Provide  design-for-manufacturing (DFM)  feedback to engineering teams.

Fabricate fixtures, tooling, and prototype structures for R&D hardware.

Document machining processes, offsets, inspection results, and lessons learned.

Maintain a clean, organized, and safe machine shop environment.

Qualifications

3+ years of CNC machining experience , ideally in a high-mix, low-volume, or R&D prototype environment.

Proficiency with at least one  CAM system  (Fusion 360, Mastercam, Hyper Mill, etc.).

Strong understanding of  GD&T , precision tolerances, and blueprint interpretation ( CNC experience with  aluminum, stainless steel, titanium , and other advanced materials.

Skilled with  manual machining  equipment (mills, lathes, drill presses, saws).

Welding certification  or practical welding experience is a strong plus.

Experience with  CMM  and advanced metrology tools preferred.

Strong communication skills and ability to document workflows clearly.

Ability to lift up to 50 lbs as needed.
