The engineer will evaluate new battery chemistries using HPPC/OCV‑SOC methodologies, conduct physics‑based electrical analyses using modeling tools such as Saber, and lead verification of algorithms including SOC, SOH, thermal runaway detection, relaxation delta voltage, and HV network diagnostics. Experience includes hands-on work in battery systems, BMS calibration/validation, propulsion or vehicle systems testing, modeling & simulation using MATLAB, Simulink, Saber, and developing ECM or physics-based models for Li-ion cell and pack behavior.
