Machinist (11:00pm to 7:30am)

Atomic Machines•Emeryville, CA

2d•$48 - $70•Onsite

About The Position

Atomic Machines is a leader in micromanufacturing, utilizing its Matter Compiler™ technology to enable new classes of micromachines. This technology offers manufacturing processes and a materials library inaccessible to traditional semiconductor manufacturing methods, aiming to democratize MEMS manufacturing and create new product categories. The company has developed an initial device made possible by this technology, which will be revealed soon. The Machinist role is based in the Emeryville, California machine shop. The position involves a modified day shift or evening shift initially, transitioning to the standard 11:00 PM to 7:30 AM shift within the first six months.

Requirements

2+ years of hands-on CNC machining experience in a fast-paced prototype or R&D environment, including 5-axis (3+2) or mill-turn work.
Demonstrated mastery of at least one modern CAM platform (Fusion 360 preferred, Mastercam, HyperMill, FeatureCAM, etc.) and comfort jumping into others.
Strong GD&T literacy – can read complex prints, hold < .001 in / 25 µm tolerances, and know when to push back on impossible callouts.
Fluent in inspection & metrology (CMM a plus) with a drive for first-article perfection.
Creative fixture and tooling mindset to design soft jaws, vacuum fixtures, and modular tombstones on the fly.
Ability to juggle multiple projects and re-prioritize as designs change, without dropping details.
Clear, proactive communicator who documents setups, shares lessons learned, and thrives in tight feedback loops with engineers.
Physical & safety readiness – able to stand for long periods, lift 50 lbs, wear required PPE, and follow all company regulations.
Familiarity with a range of materials, including aluminum, titanium, Stainless Steel, Ceramics, and Polymers.
Proficiency with manual machines, such as mills, lathes, drill presses, lapping machines, and saws.

Responsibilities

Make parts from start to finish in the machine shop.
Order tooling and materials.
Process development.
CAM programming.
Fixture design.
Manufacture parts on machines.
Perform metrology and inspection.
Provide feedback on designs to improve manufacturing speed, ease, and repeatability.
Collaborate with a small team to keep the shop clean, safe, and organized.
Enforce shop policies.
Train staff.
Interpret 3-D models & prints, plan setups, program CAM, fixture, and inspect.
Run a variety of CNC equipment (3-axis, 3 + 2, and true 5-axis mills, live-tool lathes, waterjet & laser cutters) to tolerance levels down to ± .0005 in (± 13 µm).
Develop creative work-holding and tooling solutions for one-off and low-run parts.
Program quickly and efficiently in CAM.
Perform in-process and final inspections (calipers, micrometers, height gauge, CMM).
Refine feeds/speeds, propose process improvements, keep machines maintained, and uphold EHS & dress-code standards.
Train & mentor junior machinists and shop technicians, sharing best practices in machining, metrology, and CAM workflows.
Collaborate with engineers to ensure part manufacturability and suggest design tweaks to increase quality and shorten machining time.
