Responsible for validation, installation, commissioning, and continuous improvement of test processes and equipment for power electronics (power modules and inverters) used in electric vehicles.

This role ensures safe operation, functionality, HV/LV isolation, and thermal performance of the product through robust test methods in both subassemblies and final assembly (EOL).

It is a hands-on role in manufacturing, focused on testing, not design.
- Validate the safe operation and functional performance of power modules and inverter assemblies, ensuring correct behavior under defined electrical conditions and production constraints.
- Execute and interpret HV isolation tests (HiPot / insulation resistance), confirming proper separation between high-voltage and low-voltage circuits and ensuring compliance with safety requirements.
- Verify inverter functionality at end-of-line (EOL) through system-level checks (ISC), confirming correct switching behavior, signal response, and overall system readiness.
- Work with and understand typical inverter EOL test sequences, including:




- System initiation and readiness checks
- IPM temperature sensor verification
- HV DC voltage feedback validation
- HV DC safety discharge resistor verification
- Current sensor calibration (phases U & W)
- Full current test under controlled conditions (short duration)
- NVM verification, controlled shutdown, and PCB-level checks
- Evaluate the thermal behavior of power devices (SiC MOSFETs / IGBTs), analyzing performance under load and understanding the impact of thermal resistance (Rth) and thermal impedance (Zth) on reliability and operation.
- Install, validate, and bring up test equipment in production, including setup, calibration, correlation, and ensuring stable and repeatable operation during ramp-up.
- Define and maintain test parameters, limits, and pass/fail criteria, aligned with product safety, functionality, and manufacturing requirements.
- Troubleshoot test failures in production,
