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

The Manufacturing Engineer is the technical owner of how various tools get integrated and built. Cycle times, fixturing, programming, and process maturity all flow from this seat. The difference between hitting production goals in our first quarter is largely the work this role owns.

Responsibilities

• CNC programming on 5-axis Haas UMC-500SS / UMC-750SS and DS-30Y mill-turn lathes. Goal: drop chassis-mix mill cycle from ~45 min/part to ~20 min/part over the first 12 months.

• Trumpf TruLaser 1030 + TruBend 5085 SX programming via TruTops Boost. Nest optimization, bend sequencing, ACB Laser calibration.

• Fixturing strategy: vises, soft jaws, pallet-pool tombstones, brake tooling library.

• Tool selection, tool-life tracking, and coolant/chip handling specs.

• Process documentation that holds up under operator turnover.

Required Experience

• 5+ years CNC machining / sheet-metal manufacturing engineering

• Hands-on Haas 5-axis programming (Mastercam, Fusion 360, or HSMWorks)

• Trumpf or comparable fiber-laser + press-brake experience

• Comfort owning a process from blank stock to inspected part

   

Nice-to-have

• Experience scaling a startup factory from first cube to production rate

• TruTops Boost specifically

• SEMI-grade or aerospace tolerance work

• Lights-out / pallet-pool experience
