Lead - Product Testing and Validation

BESS Testing & Validation Lead Role Summary The BESS Testing & Validation Lead owns the end-to-end verification and validation (V&V) of utility-scale Battery Energy Storage Systems. This role covers test strategy, validation planning, lab setup, prototype testing, safety validation (UL 9540A, fire/thermal), system-level performance testing, and cross-functional coordination. The engineer ensures all BESS hardware, firmware, and integrated systems meet design, reliability, safety, and certification requirements before release. Key Responsibilities Define the overall test & validation strategy of Battery modules, packs, racks, and containers PCS/Inverters, MS, EMS, and firmware, HVAC & thermal management systems Mechanical and safety systems (fire detection, suppression, ventilation) Develop Validation Master Plans (VMP), DVP&R, test cases, and test matrices. Lead testing of Electrical function (power performance, charge/discharge, SoC/SoH validation),BMS functional testing, Thermal system performance (HVAC, coolant loops, airflow, heat rejection),Communication & controls (Modbus, CAN, SCADA, EMS),Safety systems (shutdowns, interlocks, alarms) Validate system behaviour during Grid events (voltage/frequency excursions),Transients, ramp rates, and dynamic power commands, Fault injection tests (cell faults, temperature faults, communication failures) Lead internal and external testing for UL 9540 / UL 9540A thermal runaway validation,UL 1973 battery pack testing, IEC 62933 functional and safety testing, Fire, venting, suppression, and gas concentration tests Coordinate with 3rd-party certification agencies and accredited labs. Plan and execute Vibration, shock, drop, seismic tests, Thermal cycling, humidity, salt-mist, corrosion tests, Ingress protection tests (IP55/IP65),Long-duration cycle and aging tests, Evaluate system degradation, lifetime performance, and component reliability. Define test lab requirements (electrical, safety, HVAC, fire suppression). Procure, install, and maintain test infrastructure such as Cyclers, Environmental chambers, DAQs & logging systems, Load banks / Grid simulators,Fire/thermal measurement equipment Ensure safe test procedures and test lab SOPs. Analyze test data, system logs, and performance KPIs to identify design issues. Prepare detailed test reports, failure analysis documents, and corrective action recommendations. Lead root-cause analysis (RCA) with engineering teams. Cross functional collaboration with all relevant stake holders and provide feedback Required Qualifications Bachelor’s or Master’s degree in Electrical, Mechanical, Mechatronics, Controls, or related engineering field. Technical Skills Strong understanding of BESS architecture (cell → module → rack → container),Power electronics, PCS, and grid behaviour, MS & EMS functionality, Thermal management systems, Fire/thermal safety and UL 9540A principles, Skilled in using test equipment: power analysers, oscilloscopes, cyclers, load banks, CAN/Modbus tools. Knowledge of standards: UL 9540, 9540A, UL 1973, IEC 62109, IEC 62933, IEEE 1547. Experience 6–12+ years in BESS testing/validation, Battery module/pack testing,Power electronics or inverter system testing Experience leading teams and managing cross-functional projects. Prior experience working with certification bodies highly preferred.
