Location and logistics: This role is in person in South San Francisco with regular work in the lab. Travel to suppliers, manufacturers, test locations, and deployment sites is expected based on program needs. Periodic off-hours support may be required during critical builds, test campaigns, production ramps, and field escalations. Traits: Mechanical curiosity, disciplined experimental practice, skepticism of weak evidence, calm troubleshooting, and willingness to remain with a problem until it is understood. What Success Looks Like • Delivered repeatable test systems and validation evidence that enabled Dropbox assemblies to meet their reliability and release targets. • Identified critical failure modes before fleet deployment and verified effective corrective actions. • Improved correlation between accelerated testing and field performance. • Reduced test cycle time, manual effort, and failure-to-answer time through better fixtures, automation, and analysis. • Established reusable test methods that increased validation coverage and supported production and fleet expansion.
