## About the role

Peak Energy is seeking a Senior Cell Validation & Reliability Engineer to own the validation and reliability foundation for the cells integrated into our energy storage systems. This role will move beyond cell specification verification to quantify how cell-to-cell and batch-to-batch variation impacts system-level performance and reliability.

- 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
