Mechanical Engineer

About the Company

fab2 is an early-stage hardware startup founded by Sam Zeloof and Jim Keller. The team designs and builds the hardware and software needed to make chips, including the fabs, tools, and components themselves.

Responsibilities

• Design and iterate on precision machines, motion stages, structural loops, metrology frames, opto-mechanical mounts, test fixtures, and inspection tooling targeting sub-micron to nanometer performance
• Lead mechanical system integration, alignment procedures, and cross-team coordination with electrical, controls, and optics engineers
• Drive mechanical design of frames, stages, and assemblies with GD&T, tolerance analysis, and a practical eye toward manufacturability and assembly
• Rapidly prototype, build and characterize new designs on the bench using a variety of tools and characterization equipment
• Select and integrate precision components: bearings, encoders, interferometers, actuators, isolators, and dampers
• Develop error budgets and tolerance stack-ups; identify and mitigate dominant error sources (thermal, vibrational, structural, kinematic)

Requirements

• 3 years designing and building precision mechanical systems with accuracy and repeatability targets
• Working fluency in precision machine design fundamentals: exact-constraint design, kinematic couplings, flexures, error budgeting, structural loops, and tolerance analysis
• Hands-on prototyping, fabrication, assembly, and alignment experience
• Experience selecting and integrating precision components (bearings, stages, encoders, isolators, actuators)
• Experience with dimensional metrology: interferometry, LVDTs, capacitance probes, autocollimators, and CMMs

Preferred Qualifications

• Formal training in precision engineering
• Experience at an early-stage startup
• Familiarity with firmware, controls, or electrical engineering
• Opto-mechanical design and alignment experience
