Machinist San Francisco Bay Area

TAR; San Francisco (CA); On-site; USD 90,000 - 130,000; Full time

Job summary

TAR in San Francisco designs and builds the world’s first off-grid power plant for data centers powered by renewables. We are seeking a shop tech manager to operate and manage CNC milling and digital fabrication, starting with the Tormach 1100MX and CAD-based programming.

You will work hands-on in a fast-paced hardware environment, turning concepts into prototypes and manufacturable parts while collaborating with engineers to meet aggressive timelines.

Qualifications

• Hands-on experience with Tormach (or similar VMC).
• Comfortable with CAM programming and basic G-code edits.
• Experience across manual machining and digital fabrication.
• Prototype/R&D mindset with rapid iterations.
• Welding, sheet metal, or composites experience is a plus.

Responsibilities

• Set up and run our Tormach 1100MX CNC mill: fixturing, tool changes, offsets.
• Program parts from CAD (Fusion 360 or CAM).
• Operate CNC and manual machining equipment: lathe, bandsaw, drill press, grinders.
• Run our digital fabrication tools: 3D printers, laser cutter, waterjet.
• Use general shop and fabrication equipment as needed.
• Turn around one-off prototype parts quickly, speed over polish.
• Inspect parts with metrology tools, hold reasonable tolerances, flag design issues.
• Keep tooling stocked, machines maintained, and the shop clean and safe.

Job description

TAR’s mission is to power intelligence for the world. We are building the world’s first off-grid power plant for data centers powered by renewable technologies.

We firmly believe AI should be built in the US for the benefit of all people. For that, power must be fast, clean and scalable. We are singularly focused on delivering GW-scale power faster than anyone has ever done, by rethinking every layer of the stack.

We vertically integrate to solve every bottleneck, from racking systems to power electronics to dispatch algorithms to on-site construction.

Leave your mark on the future of civilization-scale energy infrastructure.

Company

TAR is both a hardware and software company, we are building out massive, critical, physical infrastructure. TAR is working directly with one of the largest compute providers to scale and deploy 5GWs by 2028.

• High ownership. High Agency. Own project end-to-end. Great people don’t need to be managed.
• Speed. We achieve great things on incredible timelines. We push ourselves to go faster.
• First principles. No ego. No hierarchy. Challenge every assumption.
• Passion. Solving the energy problem is one of the largest challenges that faces the world now and in the future.

About the role

We build robots, and robots need parts fast. This is a “shop tech manager” role with a requirement of operating a Tormach 1100MX. Operate and manage Tormach, ALD plasma table, hydraulic press brake, welding, general fabrication shop tools.

Responsibilities

• Set up and run our Tormach 1100MX CNC mill: fixturing, tool changes, offsets, the works
• Program parts from CAD (Fusion 360 or similar CAM)
• Operate CNC and manual machining equipment: lathe, bandsaw, drill press, grinders
• Run our digital fabrication tools: 3D printers, laser cutter, waterjet
• Use general shop and fabrication equipment as needed
• Turn around one-off prototype parts quickly, speed over polish
• Inspect parts with standard metrology tools, hold reasonable tolerances, flag design issues
• Keep tooling stocked, machines maintained, and the shop clean and safe

Qualifications

• Hands-on Tormach (or similar VMC) experience: you can go from drawing to finished part on your own
• Comfortable with CAM programming and basic G-code edits
• Experience across manual machining and digital fabrication: you're not a one-machine person
• Prototype/R&D mindset: okay with ambiguity, quick iterations, and parts that change weekly
• Bonus: welding, sheet metal, or composites experience, g-code, general cnc operations, plasma table, lathe
• On-site in SF

Nice to have

• Experience operating in or around a hardware, robotics, or deep-tech startup.
• A track record of standing up new functions or processes from zero.
• Comfort working alongside engineers and technical leadership.
