Job summary

fab2 is seeking a highly skilled Mechanical Engineer to design, prototype, and build the mechanical systems in our semiconductor fabrication equipment, from stages and frames up to complete systems. This role rewards hands-on prototyping and rapid iteration, with a portfolio showing items you’ve actually built.

We value precision machine design discipline and the ability to move ideas to production quickly.

Qualifications

• 3 years designing and building precision mechanical systems with real accuracy targets.
• Fluent in precision machine design fundamentals: exact-constraint design, kinematic couplings, flexures, and error budgeting.
• Hands-on prototyping, fabrication, assembly and alignment — comfortable on a mill, a granite surface plate, and with an interferometer.
• Experience selecting and integrating precision components (bearings, stages, encoders, isolators, actuators).
• Experience with dimensional metrology: interferometry, LVDTs, capacitance probes, autocollimators, and CMMs.

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 manufacturability considerations.
• 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).
