Senior Prototype Machinist (7:00am - 3:30pm)

Atomic Machines is ushering in a new era of micromanufacturing with its Matter Compiler™ technology. This full-stack technology 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. It promises to unlock MEMS manufacturing for the many device classes frustrated by semiconductor methods and to open up entirely new product classes. The Matter Compiler™ technology fully realizes the digital manufacturing dream: 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™ technology – that we will be unveiling to the world soon. Our offices are in Emeryville and Santa Clara, California. About the role: Atomic Machines is looking for a Machinist to Senior Prototype Machinist to join our machine shop in Emeryville, CA. In this role, you will take ownership of precision machined parts from start to finish, including material and tooling selection, CAM programming, fixture and workholding design, CNC setup and operation, in process inspection, and final part verification. This is a hands-on role in a fast paced prototype and R&D environment. You will work directly with engineers to turn complex designs into high quality hardware, provide manufacturability feedback, and help shorten the path from concept to functional part. The right person is comfortable moving quickly, solving ambiguous machining problems, holding tight tolerances, and adjusting priorities as designs evolve. This role supports a 24/7 machine shop operation on a 5-2 schedule, with shift assignments based on business and production needs. At the senior levels, you will also help raise the standard of the shop by improving setup practices, documenting proven processes, enforcing safe and organized shop behavior, training other users, and helping the team build repeatable systems for prototype and low volume production work. What You'll Do: Read and interpret detailed engineering drawings, CAD models, GD&T callouts, work instructions, and inspection requirements. Own machined parts from start to finish, including planning, programming, setup, machining, inspection, documentation, and delivery. Program, set up, prove out, troubleshoot, and operate CNC mills and lathes, including 3 axis and 5 axis milling equipment across multiple machines during the shift. Develop efficient CAM programs using Fusion 360 or similar platforms such as Mastercam, HyperMill, or FeatureCAM. Design setups, fixtures, soft jaws, vacuum fixtures, and other creative workholding solutions for one off, prototype, and low volume parts. Select tools, create tool lists, order tooling and materials, and prepare jobs for efficient execution. Machine precision parts across a range of materials, including aluminum, titanium, stainless steel, ceramics, and engineering polymers. Inspect parts using CMM data, calipers, micrometers, height gauges, indicators, and other metrology tools, then adjust machining processes to produce conforming hardware. Collaborate closely with engineering to identify manufacturability risks, improve designs, reduce machining time, and increase part quality. Manage multiple jobs based on priority, due dates, material availability, machine capacity, and changing engineering needs. Delegate appropriate setup, machining, inspection, and shop support tasks to shop technicians based on priority, skill level, and production needs. Document setups, inspection results, lessons learned, and process changes so future builds become faster and more repeatable. Maintain a clean, safe, organized machine shop and follow all shop policies, safety procedures, and company requirements. Train new employees, engineers, and other internal shop users on equipment, setup practices, and safe shop behavior. For senior level
