DEPARTMENT

POSITION

JOB STATUS

LOCATION

Responsibilities:

• Develop and execute Design Verification Plans & Reports (DVP&R) for advanced chemistry battery packs.

• Conduct pack-level performance validation using pack testers, inverters, solar inverters,

solar charge controllers, and chargers.

• Verify application compatibility across various power electronics systems and operational

modes.

• Perform safety-critical tests, including nail penetration, thermal runaway simulation,

overcharge/over-discharge, and short-circuit testing.

• Conduct environmental and mechanical robustness tests (thermal cycling, vibration,

humidity, dust ingress).

• Perform accelerated life testing (HALT, endurance runs) to assess pack reliability.

• Execute BMS functional verification for pack-level applications and ensure compliance

with safety cut-offs.

• Support limited cell-level characterization and BMS testing when required.

• Operate and maintain DAQs, oscilloscopes, thermal chambers, environmental chambers,

and pack test rigs.

• Conduct Root Cause Analysis (RCA) for pack-level failures and recommend design or

process improvements.

• Analyse test data to support Design for Manufacturing (DFM) and design optimization.

• Prepare detailed technical reports with test results, deviations, conclusions, and

recommendations.

• Ensure compliance with relevant IEC, BIS, UN38.3, and other applicable standards.

Communication:

Strong verbal and written skills for creating clear test plans, procedures, and reports.
