Senior Diagnostic Engineer - EV

Key Responsibilities EV Vehicle Diagnostics & Field Support

1. Lead end-to-end diagnostics of EV trucks across factory, new product introduction (NPI), on-road operations, and customer sites, covering critical systems such as VCU, BMS, MCU, EBS, BCM, TCU, and related controllers.
2. Conduct on-site investigations and resolve complex vehicle issues, including travel to field locations to support deployed vehicles and service teams when required.
3. Perform in-depth data analysis of field vehicles using diagnostic tools, CAN logs, telematics data, fault codes, and performance parameters to identify root causes of failures.
4. Execute calibration and validation of critical vehicle parameters based on real-world operating conditions and field performance.
5. Debug, isolate, and resolve software, calibration, and system integration issues observed in field vehicles.
6. Carry out bench-level and vehicle-level testing to reproduce field issues and validate corrective actions prior to deployment.
7. Support software releases by validating bug fixes, ensuring field readiness, and maintaining software and calibration version traceability.
8. Document field issues, diagnostic methodologies, root cause analysis (RCA), and corrective actions for internal stakeholders and service teams.
9. Drive continuous improvement by proposing innovative diagnostic methods, tools, and process enhancements based on field learnings.
10. Continuously learn, evaluate, and apply emerging diagnostic technologies, tools, and communication protocols relevant to EV systems and field service.
