Technical Expert – Powertrain Systems (BEV & REEV)
On-siteHanoi, Hanoi, Vietnam
Job Summary
Act as the technical authority for powertrain systems (BEV and REEV) across VinFast vehicle programs within the vehicle quality division. Lead and support resolution of all major powertrain-related issues, particularly those related to NVH, thermal performance, efficiency, and system integration. Provide expert guidance on e-motor and ICE NVH mitigation strategies, including source identification, path control, and system-level countermeasures. Lead and support definition and optimisation of powertrain thermal management strategies, ensuring robustness, efficiency, and performance across all operating conditions and climates. Provide technical leadership on coolant system architecture and HVAC compressor integration, ensuring optimal balance between efficiency, NVH, thermal robustness, and customer comfort. Contribute to vehicle efficiency and range optimisation, working closely with efficiency, calibration, aerodynamics, and thermal teams. Review and challenge powertrain concepts, detailed designs, and validation results to ensure long-term robustness and quality. Define, review, and continuously improve powertrain technical standards, design rules, and development processes. Lead technical reviews, investigations, and corrective action planning for complex powertrain topics. Capture and institutionalise learning from vehicle programs to strengthen future platform architectures and development approaches. Provide clear, authoritative technical input to senior leadership on powertrain risks, trade-offs, and strategic direction.
