Job Description

Prototype Machinist (11:00 PM – 7:30 AM)

Atomic Machines – Emeryville, CA

Pay: $47–$59 per hour

Shift: Night Shift | Full-Time

Location: Emeryville, California

Company Overview

Atomic Machines is transforming modern manufacturing with its groundbreaking Matter Compiler™ technology — a full-stack micromanufacturing platform that turns digital designs and raw materials into fully functional micromachines. This process enables the production of parts and device classes that traditional semiconductor fabrication cannot achieve, opening new frontiers in MEMS, micro-mechanics, and advanced precision engineering .

With offices in Emeryville and Santa Clara , Atomic Machines blends cutting-edge CNC machining, automation, metrology, materials science, and R&D prototyping to build hardware that hasn’t existed before.

About the Role

This Prototype Machinist (Night Shift) position begins with day-shift training (8:30 AM – 5:00 PM) for the first several months. Upon completion, the role transitions into a permanent 11:00 PM – 7:30 AM schedule.

In this role, you will own machining projects from start to finish — including CAM programming, tooling selection, fixture design, CNC machining, inspection, and documentation . You will produce tight-tolerance parts for the Matter Compiler™ and collaborate closely with engineers and prototype machinists to drive innovation in Atomic Machines’ R&D shop.

Key Responsibilities

• Interpret engineering drawings, blueprints, and 3D CAD models to develop machining plans.
• Create CAM programs using Fusion 360, Mastercam, HyperMill, or similar software.
• Operate a wide range of CNC machines, including:
  • 3-axis, 3+2, and 5-axis CNC mills
  • Live-tool CNC lathes
  • Waterjets and laser cutters
• Machine precision components to tolerances as tight as ±0.0005" (±13 µm) .
• Develop custom fixtures, tooling, and workholding 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 tooling, fixturing, and hardware for R&D assemblies.
• Document setups, offsets, inspection results, and best practices.
• Maintain an organized, clean, and safe machine shop environment.

What You’ll Need

• 3+ years of CNC machining experience in a high-mix, low-volume, or R&D environment.
• Working knowledge of 5-axis machining or mill-turn systems.
• Proficiency with at least one CAM platform (Fusion 360, Mastercam, HyperMill, etc.).
• Strong GD&T , blueprint reading, and tolerance interpretation skills (<0.001").
• Experience machining aluminum, stainless steel, titanium , and similar materials.
• Skilled in manual machining (mills, lathes, drill presses, saws).
• Welding certification or welding experience strongly preferred.
• CMM or advanced metrology experience a plus.
• Strong communication, documentation, and problem-solving abilities.
• Ability to lift up to 50 lbs.
