Job summary

fab2 is seeking a highly skilled Mechanical Engineer to design, prototype and build mechanical systems for semiconductor fabrication equipment. You will work on stages, frames and assemblies, applying precision design and rapid prototyping to deliver production-ready solutions.

You must have hands-on experience with precision machine design, tolerance analysis, and metrology, including alignment, fixtures, and interferometry. Join fab2 in Austin or San Francisco to push the limits of fabrication.

Qualifications

• 3 years designing and building precision mechanical systems with real accuracy targets.
• Proficiency in exact-constraint design, kinematic couplings, flexures and tolerance analysis.
• Hands-on prototyping, fabrication, assembly, and alignment experience on mills and benches.
• Experience selecting and integrating precision components (bearings, encoders, actuators).
• Experience with dimensional metrology (interferometry, CMMs, probes).

Responsibilities

• Design and iterate on precision machines, motion stages, frames, and tooling for sub-micron to nanometer performance.
• Lead mechanical system integration and cross-team coordination with E/C/O engineers.
• Drive design of frames and assemblies with GD&T and manufacturability in mind.
• Rapidly prototype, build and characterize new designs on the bench with varied equipment.
• Develop error budgets and tolerance stack-ups; identify dominant error sources.
