• Implement vehicle functions such as:
  • Vehicle startup and shutdown
  • Torque control
  • Regenerative braking
  • Drive mode logic
  • Charging control
  • Thermal system control
  • Interlocks and safety monitoring
  • Body and auxiliary functions
• Develop and maintain CAN communication interfaces.
• Integrate new components including:
  • Inverters
  • Motors
  • Battery management systems
  • Chargers and EVCCs
  • DC/DC converters
  • Thermal controllers
  • Smart PDUs
  • Body controllers
• Support implementation and integration of EV charging functionality.
• Support DIN 70121, ISO 15118-2, ISO 15118-20, and V2G development as required.
• Develop CAN signals, diagnostic messages, DTCs, and DIDs.
• Analyze CAN logs and vehicle data to troubleshoot software and system issues.
• Support vehicle testing and software validation.
• Develop configurable software that can support multiple vehicle platforms.
• Maintain software versions, calibration files, and release documentation.
• Support engineering, production, service, and supplier teams with software-related issues.
• Participate in vehicle commissioning and prototype development.
• Support software flashing, configuration, and diagnostic tools.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Mechanical Engineering, Mechatronics, Computer Science, or related field.
