  • Bachelor’s degree in mechanical engineering or related field (master’s preferred)
  • Strong understanding of electromechanical systems, thermodynamics, and energy conversion
  • 4 + years for Powertrain domain experience much required. Also experience in sizing propulsion components for automotive.
  • Proficiency in modelling and simulation tools (e.g., MATLAB/Simulink, GT-Suite, Excel VBA)
  • Familiarity with BEV/xHEV architectures and performance requirements
  • Knowledge of automotive development processes and system engineering principles
  • Strong analytical, communication, and documentation skills


Preferred Experience

  • Prior experience in electrified powertrain development or system architecture
  • Exposure to battery pack sizing, inverter thermal limits, and motor torque-speed mapping
  • Understanding of vehicle-level drive cycles and energy consumption modelling
  • Experience with requirement management tools (e.g RMDV , TRM, XRAY)
