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, HyperMill, 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 workholding 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, HyperMill, etc.).
• Strong understanding of GD&T, precision tolerances, and blueprint interpretation (<0.001").
• 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.
