About the job
Leads system-level reliability for home energy products, from hardware design and qualification testing through field deployment and failure investigation.
What you'll do
- Set reliability strategy, requirements, qualification and accelerated-life test plans, and drive DFMEA and design-for-reliability activities.
- Lead root-cause investigations of power electronics and PCBA failures, validate containment and countermeasures, and apply failure-analysis techniques.
- Track field reliability, use Weibull and lifetime modeling to project performance, and communicate risks for product release readiness.
What they ask for
- Degree in Mechanical Engineering, Electrical Engineering, Chemical Engineering, Physics, or equivalent.
- Experience with accelerated life testing models and governing equations, applied reliability statistics (e.g., Weibull analysis), and risk analysis.
- Proven track record leading cross-functional root-cause investigations in a fast-moving hardware company.
- Working knowledge of failure-analysis techniques including optical microscopy, SEM, CSAM, X-ray, cross-sectioning, and EDX.
Nice to have
- Familiarity with PCBA reliability best design practices and failure physics in PCBAs and common power electronics components.
- Working knowledge of the theory of operation of common power converter topologies.
