Job summary

fab2 is looking for a skilled Mechanical Engineer to design, prototype, and build mechanical systems for semiconductor fabrication equipment. You will create stages, frames, and assemblies with a focus on precision and manufacturability, driving projects from concept to bench validation in days or weeks.

Applicants should demonstrate hands-on fabrication and alignment experience, GD&T expertise, and a track record of delivering high-precision systems.

Qualifications

• 3 years designing and building precision mechanical systems that hit real accuracy targets.
• Working fluency in precision machine design fundamentals: exact-constraint design, kinematic couplings, flexures, error budgeting, structural loops, tolerance analysis.
• Hands-on prototyping, fabrication, assembly, and alignment experience with mills, granite surfaces, and interferometers.

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).
