Welder Fabricator

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.

About the team

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.

About the role

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.

Responsibilities

• 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 TruLaser 1030 (4 kW fiber) operation: nesting, sheet loading, scrap handling, nozzle changes, beam calibration

• Trumpf TruBend 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

Required Experience

• 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

Nice-to-have
