Machinist / Welder

Atomic Machines is ushering in a new era in micromanufacturing with its Matter Compiler™ technology. The Matter Compiler™ enables new classes of micromachines to be designed and built by offering manufacturing processes and a materials library that is inaccessible to semiconductor manufacturing methods. The Matter Compiler™ promises to unlock MEMS manufacturing both for the many device classes that never could be made by semiconductor methods but also to open up entirely new classes. Furthermore, the it is fully digital in the way 3D printing is digital, but where 3D printing produces parts of a single material using a single process, the Matter Compiler™ is a multi-process, multi-material technology : bits and raw materials go in and complete, functional micromachines come out. The Atomic Machines team has also created an exciting first device – one that was only made possible by the existence of the Matter Compiler™ that we will be unveiling to the world soon.

Our offices are in Emeryville and Santa Clara, California.

About The Role

As a Machinist / Welder, you will be responsible for making parts from start to finish in our machine shop in Emeryville. This includes ordering tooling and materials, process development, CAM programming, fixture design, manufacturing the parts on the machines, metrology / inspection, and welding. You will also provide feedback on designs to make manufacturing faster, easier, and more repeatable for both machined parts and weldments. You will think quickly, produce quality work, and anticipate concerns before they become blockers. Additionally, you will collaborate with a small team of machinists in charge of keeping the shop clean, safe, and organized, enforcing shop policies, and training staff.

What You'll Do

• Interpret 3D models and engineering drawings to plan setups, program CAM, design fixturing, and run inspection workflows.
• Operate a variety of CNC machines (3-axis, 3+2, and 5-axis mills; live-tool lathes; waterjets; and laser cutters) while maintaining tolerances down to ±0.0005 in (±13 µm).
• Develop innovative work-holding and tooling solutions for prototyping.
• Generate efficient CAM programs, manage tool libraries, and maintain CAM templates.
• Perform in-process and final inspections using calipers, micrometers, height gauges, and CMM.
• Optimize feeds and speeds and drive continuous improvements in shop processes.
• Perform TIG and MIG welding on aluminum, stainless steel, and steel, including welds for high-vacuum and hermetic seals.
• Interpret drawings with welding symbols and build directly from 3D models or prints.
• Fabricate precision weldments, ensuring alignment, squareness, and cosmetic quality.
• Maintain welding equipment, prepare materials (cutting, grinding, cleaning), and ensure proper fit-up and penetration.
• Collaborate with engineers and machinists to provide design-for-manufacturing feedback on machined and welded parts / assemblies.
• Support fabrication of tooling, fixturing, and other structures for R&D hardware.
• Document setups, offsets, inspection results, and lessons learned to strengthen tribal knowledge.
• Uphold safety protocols, PPE usage, and compliance with company standards.
• Contribute to shop cleanliness, organization, and equipment readiness.
• Proactively manage assigned projects to deliver results on schedule.
