Technical Expert – Powertrain Systems (BEV & REEV)

Job Overview

This role offers a unique opportunity to shape the core performance, refinement, thermal robustness, and efficiency characteristics of VinFast’s electrified powertrains. As a senior technical expert, the successful candidate will directly influence NVH quality, thermal architecture, efficiency, and driving experience, playing a central role in defining the technical DNA of current and future BEV and REEV platforms.

Experience

• Expert in battery electric vehicle (BEV) and range-extended electric vehicle (REEV) powertrain systems.
  
• Deep technical knowledge of electric motors, inverters, gearsets, reduction transmissions, and driveline systems, including full vehicle integration.
  
• Extensive experience in identifying, analysing, and resolving NVH issues related to e-motors, including electromagnetic excitation, torque ripple, gear whine, and structure-borne noise paths.
  
• In-depth expertise in powertrain thermal management, including:
  
• Motor, inverter, and power electronics cooling
  
• Battery thermal interaction with powertrain systems
  
• Coolant circuit design, control strategies, and heat rejection optimisation
  
• Strong practical experience with coolant systems, including pumps, valves, heat exchangers, and integrated thermal architectures.
  
• Proven experience working with and optimising HVAC compressor systems (electric compressors), including their interaction with powertrain thermal loads, efficiency, NVH, and customer comfort.
  
• Demonstrated capability to support and guide efficiency optimisation activities, including loss reduction, thermal efficiency trade-offs, calibration strategies, and system-level optimisation.
  
• Experience working closely with NVH, Thermal, Efficiency, Vehicle Dynamics, Electrical, and HVAC teams to deliver balanced and robust powertrain solutions.
  
• Solid understanding of how powertrain behaviour influences driveability, refinement, customer perception, and overall driving experience.
  
• Ability to define, review, and enforce powertrain design rules, best practices, and technical standards across multiple vehicle programs.
  
• Strong background in root-cause analysis and structured problem solving for complex, cross-attribute powertrain issues.
  
• Proven experience capturing lessons learned and translating them into standards, guidelines, and future platform strategies.
  

Position Responsibilities

• 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.
  

• Bachelor’s degree or higher in Mechanical Engineering, Automotive Engineering, or a related discipline.
  
• 15–20+ years of experience in chassis system development within industry-leading OEMs or Tier-1 engineering organisations.
  
• Exceptional depth of technical knowledge combined with strong systems-level thinking.
  
• Ability to influence and lead without direct line management, operating effectively as a senior technical authority.
  
• Excellent communication skills, capable of explaining complex powertrain and thermal topics to both technical and non-technical stakeholders.
  
• Structured, analytical, and detail-oriented approach to problem solving.
  
• Comfortable working in a fast-paced, high-expectation environment with significant technical accountability.
