• Design prototype fixtures, concept designs, test coupons, and mechanical assemblies in SolidWorks
• Fabricate and iterate prototypes using rapid prototyping and external machine shops
• Execute lab bring-up of new fixtures and test platforms; own first-article validation
• Perform surface profiling, substrate warpage, and TTV measurements
• Set up and run pressure mapping, electromigration, and compression characterization tests
• Document test procedures, measurement data, and failure analyses

Qualifications

• BS in Mechanical Engineering or related field (MS preferred; equivalent hands-on experience considered)
• Able to work full-time on-site in Saratoga CA
• Proficient in SolidWorks — 3D modeling, assemblies, drawings, GD&T
• Demonstrated hands-on rapid prototyping experience (FDM, SLA, CNC, or equivalent)
• Practical lab skills: instrumentation setup, data acquisition, measurement
• Ability to work in a cleanroom environment
