Job description

Oscilloscopes, digital multimeters (DMM), basic bench power supplies, schematics reading.

Good to have: dSPACE HIL bench development, MATLAB/Simulink, high/low voltage battery management systems (BMS), failure root-cause analysis (FMEA).

The Electrical Systems test engineer requires hands-on electrical verification of power generation, low-voltage battery systems, power distribution units, wiring harnesses, across full vehicles, HIL benches, and lab test fixtures..

Sets up physical lab benches, connects harness break-out boxes, and executes pre-defined electrical test cases under guidance.

Independently creates and runs electrical stress tests for low-voltage battery modules, power rails, and electromechanical actuators. Troubleshoots harness issues and component anomalies.

Collaborate on and assemble electrical test platforms that use power equipment including, but not limited to, power supplies, electronic

loads, oscilloscopes and low voltage batteries.

Electrical V&V: Author of comprehensive electrical test plans. Diagnoses complex electrical noise, ground loops, power brownout conditions, and transient voltage spikes across high- and low-voltage vehicle interfaces.
