Shift Supervisor (Machine Shop) (7:00am - 3:30pm)

About Atomic Machines:

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.

Day Shift Schedule:

This role will begin on a modified day shift schedule (8:30am - 5:00pm) to support ramp-up and training, and will transition within the first six months to the standard shift hours of 7:00am - 3:30pm.

About the role:

As the Lead Machinist/Shift Supervisor, you will guide the day to day operation of our prototype machine shop in Emeryville. You will produce high quality parts from start to finish, but you will also oversee workflow, assign work to machinists, and ensure that the shop runs safely, efficiently, and with a continuous improvement mindset. You will coordinate resources, train and coach junior machinists, enforce shop standards, and serve as the primary point of contact for engineering teams during your shift.

You will think ahead, remove roadblocks, and uphold a culture of excellence in machining, safety, and organization.

What You Will Do

• Own machining execution and capability across the shift by personally performing and overseeing setup planning, CAM programming, fixturing design, and inspection for complex, high precision parts.
• Independently mill and deliver company critical components across a wide range of CNC platforms including 3-axis, 5-axis, and mill/turn centers, setting the benchmark for precision, speed, and workmanship.
• Write, debug, and optimize CAM programs and toolpaths for challenging geometries and tight tolerances, and establish best practices that are adopted consistently by the team.
• Plan, prioritize, and protect daily machining schedules by balancing machine capacity and program urgency in a dynamic R&D environment.
• Serve as the primary manufacturing interface for engineering during the shift by providing real time feedback on risk, schedule, and design for manufacturability based on direct machining experience.
• Ensure clean handoffs and operational continuity across shifts through disciplined documentation, communication, and coordination with other shift leads.
• Lead and develop a team of machinists by setting clear expectations, defining daily and longer term goals, and maintaining consistent, transparent communication.
• Foster a collaborative, high trust shop environment where machinists are supported, informed, and empowered to execute high quality work.
• Conduct regular performance check ins, provide actionable technical and behavioral feedback, and remove systemic blockers that limit productivity or quality.
• Hold the team accountable for safety, quality, and workmanship while modeling professionalism, technical rigor, and calm decision making under pressure.
• Train and mentor machinists and technicians through hands-on instruction in machining fundamentals, advanced CAM workflows, GD&T, and metrology techniques.
• Support career growth and skill progression while reinforcing a culture of precision, ownership, safety, and continuous learning.
• Own shift level tooling and material readiness, including procurement and inventory decisions that support uninterrupted production.
• Monitor machine performance, identify reliability risks, and coordinate with facilities and equipment teams to minimize downtime and protect capacity.

What You Will Need

• Five or more years of hands-on CNC machining experience in prototype or research and development environments, with deep expertise in milling high precision parts.
• Demonstrated expert level hands on experience machining high precision parts in prototype or research and development environments, including advanced 5 axis and mill/turn platforms.
• Demonstrated expert level proficiency in CNC milling across 3-axis and 5-axis platforms, with experience on mill/turn centers.
• Deep mastery of at least one modern CAM system (Fusion preferred) with the ability to personally program complex parts and coach others on efficient, robust workflows.
• Advanced literacy in GD&T with proven ability to interpret complex prints, hold sub thousandth tolerances, and identify manufacturability risks.
• Strong proficiency in inspection and metrology, including experience with CMMs and in process inspection techniques.
• Proven capability designing fixtures and tooling for complex, high mix work, including scalable and repeatable workholding solutions.
• Demonstrated ability to manage multiple competing priorities, adapt plans as designs evolve, and maintain quality under schedule pressure.
• Commitment to safety, professionalism, and compliance with all required PPE and shop practices.
• Prior experience leading, mentoring, or coordinating machinists or technicians in a production or R&D environment.
• Physical readiness to stand for long periods, lift 50pounds, wear required PPE, and follow all company safety regulations.
