Senior Hardware Reliability Engineer

Join our team as a Senior Hardware Reliability Engineer in the San Francisco Bay Area. In this hybrid role, you will be the core technical owner for the reliability of integrated humanoid drive systems and robotic actuation sub-assemblies. You will collaborate with various teams to drive reliability validation, lead multi-physics failure analyses, and build robust lifetime models for highly dynamic robotic hardware. The ideal candidate will have 5-8+ years of experience in reliability engineering for complex hardware systems, with a strong understanding of mechatronic systems and experience in robotics, autonomous vehicles, aerospace, or other high-reliability industries.

• Partnership with design, controls, embedded software, and manufacturing teams to drive reliability validation and lead multi-physics failure analyses.
• Implementation of Design for Reliability (DfR) methodologies across complex mechatronic loops, including drive trains, harmonic gearboxes, BLDC motors, encoder feedback systems, and dynamic wire harnesses.
• Design, build, and execute multi-axis accelerated stress testing setups, including HALT, HASS, dynamic load cycling, thermal shock, vibration, and ingress protection (IP) validation.

• Strong preference for candidates with experience in robotics, autonomous vehicles, aerospace, or other high-reliability industries
• Minimum of 5 to 8+ years of experience in reliability engineering for complex hardware systems
• Demonstrated experience with reliability engineering principles including Design for Reliability, DFMEA/FMEA, accelerated-life testing, reliability demonstration, reliability growth, component derating, and physics-of-failure analysis
• Familiarity with statistical reliability methods including Weibull analysis, success-run testing, confidence bounds, and accelerated-life modeling
• Working knowledge of fatigue and life-prediction methods such as Coffin-Manson, stress-life, strain-life, Miner’s rule, or equivalent approaches
• Strong understanding of mechatronic systems integrating mechanical structures, electronics, actuators, sensors, and control hardware
• Ability to interpret mechanical drawings, electrical schematics, test data, material specifications, and supplier qualification reports
• Understanding of common mechanical, electrical, and electromechanical failure mechanisms
• Experience developing or executing environmental and durability tests such as vibration, thermal cycling, mechanical fatigue, humidity, HALT, or accelerated endurance testing
• Ability to learn and effectively use new reliability and engineering software tools as needed
• Ability to analyze life data, accelerated-test results, failure distributions, and reliability-growth trends
• Proficiency with data-analysis and scripting environments used for engineering analysis is preferred
• Experience using reliability, statistical, simulation, and engineering analysis tools to support reliability assessments and decision-making
• Experience applying physics-based simulation or analytical methods to evaluate mechanical, thermal, vibration, fatigue, or electronics reliability risks
• Bachelor’s degree in Mechanical Engineering, Electrical Engineering, Mechatronics, Materials Science, Reliability Engineering, or a related technical field
• Master’s degree or PhD is a plus
