Job summary

fab2 is building a new generation of semiconductor manufacturing equipment.

We are staffing up our first production facility in Texas, and the CNC programmer role owns the CAM programs for our Haas fleet—three UMC-500SS five-axis VMCs, one UMC-750SS, two DS-30Y mill-turn lathes—and targets cutting cycle times from ~45 min/part to ~20 min/part through smarter toolpaths, fixturing, and disciplined documentation.

Qualifications

• 4+ years CNC programming experience, including 2+ years on 5-axis.
• Strong fluency with Mastercam, Fusion 360, or HSMWorks.
• Haas control native or comparable Fanuc/Siemens.
• GD&T fluency; able to read drawings to spec.
• Documented track record of reducing cycle times for part families.

Responsibilities

• CAM programming for 5-axis VMC and mill-turn work.
• Develop toolpath strategies for stainless and aluminum semiconductor-grade parts.
• Probing routines for in-process inspection.
• Tool library, tool-life tracking, and offset management.
• Pallet-pool lights-out programs for the Haas fleet.
• Provide DFM feedback to design team to improve speed.
• Create process documentation for operator handover.

Job description

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.

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

fab2 is building a new generation of semiconductor manufacturing equipment. We're staffing up our first production facility, and the CNC programmer is the seat that decides how fast we can build them.

You own the CAM programs that run our Haas fleet - three UMC-500SS five-axis VMCs, one UMC-750SS, two DS-30Y mill-turn lathes. Today our chassis mix mill cycle is ~45 min/part. Your year-one target is to drop that to 20 min/part through better toolpaths, smarter fixturing, optimized tool selection, and disciplined process documentation. That single number controls how many cubes we can ship per month.

Responsibilities

• CAM programming for 5-axis VMC and mill-turn lathe work (Mastercam, Fusion 360, or HSMWorks)
• Toolpath strategy on stainless and aluminum semiconductor-grade parts (typical ±0.001")
• Probing routines for in-process inspection
• Tool library, tool-life tracking, and offset management at the Zoller presetter
• Pallet-pool lights-out programs for the UMC fleet
• DFM feedback to the design team - "this would run 30% faster if you opened that radius up"
• Process documentation that survives operator turnover

Required Experience

• 4+ years CNC programming, including 2+ years on 5-axis
• Strong Mastercam, Fusion 360, or HSMWorks fluency
• Haas control native (or comparable Fanuc/Siemens)
• GD&T fluency, comfortable reading drawings to spec
• Documented track record of taking specific part families from high cycle time to low

Nice-to-have

• Trunnion-mount 5-axis programming
• Pallet-pool / lights-out experience (Fastems or similar)
• Mill-turn programming on DS-30Y class machines
• Semiconductor, aerospace, or medical-device part background
• Mastercam Multi-Axis or HSMWorks Adaptive Clearing certification
