The opportunity

Job Title: Senior Cell Validation & Reliability Engineer

What you'll do

  • Validate the electrical and mechanical integration of supplier cells into: Peak Energy ESS platforms; own the cell-side validation verdict at each integration point.

  • Move validation from spec verification to population statistics: design cell-to-cell and batch-to-batch variation studies and quantify how variance propagates to system-level performance — balancing burden, thermal gradients, mechanical preload windows, and energy/power delivery.

  • Mechanical: validate cell behavior under system-representative compression;: characterize force versus state of charge and swell over life; deliver force–displacement–life datasets that inform foam/pad selection and preload design by systems engineering.

  • Electrical & BMS: Assist in analysis with measured variation accounted for of OCV characterization, equivalent-circuit parameters; quantify cell-in-system versus bench performance deltas.

  • Establish the statistical foundation: measurement system analysis (MSA / Gauge R&R) across cell test equipment, capability analysis against specification, and statistically justified sample sizes, acceptance criteria, and validation exit criteria.

  • Own the cell reliability test roadmap: inform sample size requirements for calendar life, cycle life, and accelerated aging test plans designed explicitly to inform reliability analysis — not only to characterize performance.

What they're looking for

  • Deliver the authoritative cell-level input to system reliability evaluation:: failure-rate estimates, life distributions under product duty cycles, degradation trajectories, and derating guidance.
  • Track reliability performance across supplier lots and chemistries;: participate in root cause analysis of cell-related reliability failures and feed findings back into test plans and supplier requirements.
  • Own the cell-requirements and reliability-input handoffs; participate in DFMEAs for cell-driven failure modes.
  • Share variation and reliability findings with supplier quality: this role owns the performance and reliability implications of variation.
