  • Integrate IO & Plant Models and maintain Model architecture roll-out for different systems.
  • Create test specifications from System/software/controls requirements and validate using dSPACE platform tools.
  • Automate test cases using Python and execute the test script.
  • Coordinate HIL bench deployment and support for Propulsion systems HIL benches.
  • Plan, communicate, and coordinate HIL Test strategy and automation framework rollout.
  • Design and develop fault injection solutions for sensors, actuators, and communication buses.
  • Design hardware simulators for vehicle components such as inverters, motors, batteries, fuel cells, etc.
  • Develop HIL harnessing and hardware interfaces for simulated components.
  • Develop support Human Machine Interfaces (HMI) or GUI for HIL test execution and rapid prototyping.
  • Maintain HIL system architecture following requirement updates and evolution.
  • Develop HILST test environments for Vehicle ECU subsystems testing, verification, and validation.
  • Design/Develop HILST environment using a model-based engineering approach (Simulink / Stateflow).
  • Capture functional requirements for HILST environment to satisfy ECU/Systems test.
  • Support development of bespoke modules and configure commercial tools as required.
  • Produce and deliver HIL Systems to a defined release plan.
  • Simulink S-Function development and integration for Plant/Controller Function Simulation.
  • Use/integrate Plant/Vehicle Models as required (Carmaker/DSpace ASM).
  • Utilize Test Automation Tools (Automation Desk/Python Development).
  • Deliver software test results to Engineering and support development of test requirements with system engineers.
  • Work collaboratively with other HIL engineers to align processes and improve development efficiency.



  • Minimum of 7+ years’ experience of relevant automotive systems.
  • Expertise in MATLAB Simulink, Simscape, Stateflow, M scripting.
  • Experience in Test Automation using Python.
  • Experience in System Testing and HIL commissioning using dSpace and NI HiL Real-Time platforms.
  • Familiarity with dSPACE ASM, ControlDesk, ConfigurationDesk, BusManager.
  • Experience in Motor Plant Modelling.
  • Proficiency in Vector tools (CANanalyzer, CANoe).
  • Experience in Electric and hybrid powertrains, HV energy management, HV propulsion drives, fuel cells, batteries, EV thermal management.
  • Knowledge of configuration management & requirements tools (e.g., Polarian/SVN/Git).
  • Experience with ePowertrain Signal Level and Power level.
  • Strong issue debugging skills.
  • Comprehensive ASM and HIL expertise.
  • Ability to read schematics and work with hardware engineers.
  • Proficiency in using CAN, LIN, Flexray, Ethernet, RS232, FPGA, DSP. Experience using Software configuration tools, Automated test tools script writing.
  • Experience using Software configuration tools, Automated test tools script writing.
  • Plant modeling and development experience of real-time control systems.
  • Highly motivated with strong organizational, project management, and communication skills.
