• Coordinate with hardware, software and algorithm teams to ensure MCU functionality aligns with vehicle performance requirements.
• Perform fault diagnostics, troubleshooting and root-cause analysis for MCU and motor-related issues.
• Contribute to Functional Safety (ISO 26262) and SOTIF compliance at the vehicle level, including ASIL verification and safety case development.
• Implement and monitor vehicle-level calibration strategies for motor control loops, torque ramping and regenerative braking.
• Support prototype and pre-production vehicle integration, wiring harness validation and ECU configuration.
• Develop and maintain test plans, verification reports and integration documentation.
• Collaborate with OEMs, Tier-1 suppliers, and cross-functional teams to meet program milestones and quality objectives.

Qualifications: 

• Bachelor’s or Master’s degree in Electrical Engineering, Mechatronics, Automotive Engineering or related discipline.
• 4-8 years of experience in vehicle integration of motor control systems or power electronics.
• Strong understanding of electric motors (BLDC, PMSM, induction) and motor control strategies.
• Hands-on experience with vehicle communication networks (CAN, Ethernet etc.).
• Knowledge of Functional Safety (ISO 26262) and ASIL compliance for powertrain systems.
• Experience with vehicle testing, calibration, and validation of MCUs.
• Familiarity with diagnostics, fault analysis, and HIL/SIL testing.
• Understanding of vehicle electrical architecture, wiring harnesses, and ECU integration.
• Proficiency in MATLAB/Simulink oxperience with traction motor integration in EVs or hybrid vehicles.
• Familiarity with battery management systems and regenerative braking coordination.
• Exposure to on-road testing and chassis dynamometer validation of motor control systems.
• Experience with model-based calibration and tuning for motor control loops.
• Knowledge of OTA updates and ECU software lifecycle management.r equivalent tools for motor control validation.
• Strong analytical and problem-solving skills.
• Excellent communication and cross-functional collaboration.
• Ability to manage multiple integration tasks across vehicle programs.
• Detail-oriented with a focus on safety, performance, and reliability.
