Senior FA Engineer, Opto-Mechanical Modules

Google LLC; Fremont (CA); Hybrid; USD 159,000 - 230,000; Full time

Job summary

Google's XR team is seeking a Senior Failure Analysis Engineer to lead end-to-end FA investigations for next-generation Light Engine Assemblies and microLED displays. You will diagnose failures from NPI, reliability tests, and field returns, and drive root-cause actions with cross-functional teams.

The role requires hands-on experience with SEM/EDX, FIB, TEM, X-ray/CT, and other FA techniques, along with strong collaboration and documentation skills to deliver actionable reports and robust

Qualifications

• Bachelor's degree in Materials Science, Optical engineering, Electrical Engineering, Physics, Mechanical Engineering, or equivalent practical experience.
• 4 years of experience in a failure analysis role for displays or semiconductor modules.
• Experience with optoelectronic modules, including working principles, manufacturing and assembly, testing and characterization, and failure modes.
• Experience operating physical failure analysis (FA) tools (e.g., SEM/EDX, FIB, X-ray, cross-section/polishing, optical microscopy) and electrical fault isolation equipment.

Responsibilities

• Support end-to-end failure analysis (FA) investigations for next-generation Light Engine Assemblies (LEAs), including microLED displays, modules, and associated sub-components.
• Analyze and diagnose component failures from NPI builds, reliability qualification testing, production excursions, and field returns.
• Perform lab analysis using advanced techniques, including electrical testing, optical setups, firmware debugging, SEM/EDX, FIB, TEM, X-ray/CT inspection, SAM, micro-probing, and physical cross-sectioning.
• Define and standardize FA workflows, fault isolation procedures, and Turnaround Time (TAT) performance metrics.
• Pinpoint underlying physical failure mechanisms and collaborate with design, process, and quality teams to implement root-cause solutions and corrective actions.
