Manufacturing Jobs in Sunnyvale, CA (Now Hiring) — 902 open — Page 16

About the role

• We're looking for a Hardware Reliability Test Engineer to own environmental and durability qualification for LyteVision modules and the custom silicon inside them (LyteCore SoC, analog front-end, laser control chip). You'll design and run the test programs that prove our sensors survive vibration, thermal cycling, humidity, shock, and years of field duty — and you'll turn failures into root causes the design team can act on. This is a hands-on role: you'll be in the lab running HALT/HASS chambers as often as you're in front of a laptop analyzing failure data.

What you'll do

• Design, execute, and analyze HALT (Highly Accelerated Life Testing) and HASS (Highly Accelerated Stress Screening) programs for LyteVision modules and subassemblies.
• Build and run test plans for vibration, mechanical shock, thermal cycling, thermal shock, humidity/condensation, dust/ingress (IP rating validation), and EMI/EMC.
• Characterize optical and sensor performance drift under environmental stress.
• Define accelerated life test models and translate chamber results into field-life reliability predictions (e.g., MTBF/MTTF estimates, Weibull analysis).
• Lead failure analysis (FA) on units that fail in test or in the field — coordinate with silicon, optics, and mechanical teams to drive root cause and corrective action.
• Own reliability test fixtures and chamber infrastructure; work with contract labs when internal capacity is constrained.
• Contribute reliability requirements and DFR (Design for Reliability) input early into new module and PCB designs, alongside the hardware and silicon teams.
• Maintain test documentation, qualification reports, and traceability suitable for customer and regulatory review.
• Support functional safety and durability claims for robotics, automotive-adjacent, and industrial deployment environments.

Required Qualifications

• 2–4 years of experience in hardware reliability engineering, environmental test engineering, or product qualification — ideally on sensors, optics, consumer electronics, or automotive-grade hardware.
• Hands-on experience running HALT/HASS chambers, vibration tables, and thermal chambers.
• Working knowledge of reliability statistics: MTBF/MTTF, Weibull analysis, accelerated life testing models (Arrhenius, Coffin-Manson, etc.)
• Experience with failure analysis techniques or close partnership with FA labs.
• Familiarity with relevant standards (e.g., MIL-STD-810, IEC 60068-2, IPC/JEDEC, ISO 16750, or automotive/industrial equivalents).
• Comfort working with optical or MEMS-based sensing hardware, or strong appetite to learn — our modules combine photonics, analog electronics, and custom silicon.
• Bachelor's or master's degree in mechanical engineering, Electrical Engineering, Materials Science, or a related field.
• Strong instincts for root-causing ambiguous failures and communicating findings clearly to cross-functional hardware and silicon teams.

Preferred Qualifications

• Experience testing sensor modules for robotics, AMRs, or autonomous vehicle platforms
• Exposure to functional safety processes (ISO 26262 or similar)
• Experience working with contract manufacturers or OSAT partners on qualification builds

Benefits (subject to location and local regulations)

• Competitive salary and equity
• Comprehensive medical, dental, and vision coverage
• 401(k) retirement plan
• Flexible vacation and time-off policy
• Collaborative, fast-paced, and inclusive work environment
• Opportunity to work on cutting-edge technologies with a highly cross-functional team
