Welder-Fabricator; Flex Operator

About fab2

The fab2 team can build anything. We design all the hardware and software needed to make chips and we make the fabs, tools, and components ourselves.

We're looking for exceptional, hands-on people who can iterate to the limits of what's possible.

fab2 was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.

The fab2 production team manufactures chip fabs. From deposition and etching tools to lithography and metrology, we are building every tool ourselves. We fabricate the metal parts, operate SMT lines to build PCBAs, and assemble the tools in-house.

This role sits within the overall Production team. Given that sheet metal, tube bending, and TIG welding all feed each other on the cube, we are excited to be adding cross‑trained flex operators who can run any of the fabrication cells as the daily mix shifts.

• Manual TIG welding on stainless gas‑distribution tubing and Al/SS chamber weldments (Miller Dynasty 280 DX ×2)
• Helium‑leak‑tight standards on vacuum‑prep welds.
• Trumpf Tru Laser 1030 (4 kW fiber) operation: nesting, sheet loading, scrap handling, nozzle changes, beam calibration
• Trumpf Tru Bend 5085 SX press brake setup and operation with ACB Laser closed‑loop angle control
• FINISHLINE 42  two‑zone deburr operation
• First‑article inspection across welded, bent, and laser‑cut parts; pre/post‑weld cleaning to semi‑grade standards

• 3+ years total experience across at least TWO of: TIG welding manual, sheet metal fabrication (laser + brake).
• Strong TIG welding background — manual on Al and SS, can pass AWS D17.1 or equivalent quality bend tests
• Reads weld symbols, flat patterns, and tube prints fluently
• Comfortable being the kind of operator who runs a different machine each day

• Strong proficiency with all three of: TIG + sheet metal + tube
• Trumpf laser + brake specifically (or Bystronic / Mazak / Amada)
• Welding Inspector certification (CWI)
• Tru Tops Boost or T PROJECT programming
• Robotic / cobot weld cell familiarity (UR + Miller Copilot)

• Medical, Dental, and Vision insurance
• Generous Paid Time Off inclusive of Holidays and Sick Time
