Senior Cell Validation & Reliability Engineer
$150,000–$190,000 year
On-siteBurlingame, California, United States
Job Summary
Design cell-to-system integration validation studies that quantify population variance impacts on energy storage performance, moving beyond spec verification to deliver statistically justified verdicts. Own the cell reliability test roadmap, including sample size requirements for calendar and cycle life, while generating authoritative inputs such as failure rates and degradation trajectories for system evaluation. Establish statistical foundations through measurement system analysis and capability studies, then pair with modeling teams to validate equivalent-circuit and thermal predictions. Translate complex test data into actionable engineering decisions that inform 20-year life expectations and supplier requirements.
Required Qualifications
- B.S. in Mechanical, Electrical, or Chemical Engineering or a related field
- M.S. preferred
- 5+ years in battery cell/module/pack validation or reliability engineering within automotive or stationary energy storage
- Reliability statistics: Weibull / life-data analysis, accelerated life testing, and confidence-bound methods for life claims
- Applied statistics in an engineering context: design of experiments, capability analysis, measurement system analysis, sample-size justification
- Hands-on familiarity with cell test methods: cyclers, environmental chambers, force/displacement measurement, and thermal instrumentation
- Depth in one integration axis — mechanical (compression, thermal interface) or electrical (BMS, system electrical performance) — with working competence in the other
- Working knowledge of BMS fundamentals: SOC/SOH estimation, cell balancing, and protection limits
- Proficiency in Python or equivalent for engineering data analysis
Desired Qualifications
- Reliability methods: reliability block diagrams, failure-rate (FIT) allocation, MTBF modeling
- Experience owning DVP&Rs and driving validation programs from plan through sign-off
- Sodium-ion or LFP cell experience
- Experience partnering with modeling teams on equivalent-circuit, thermal, and degradation model validation
- DFMEA participation on module/pack programs
