About Role

We are seeking an experienced Motor Controller Developer with expertise in Power Electronics, Embedded Systems, and EV Motor Control. The ideal candidate will have hands-on experience with Bootloader development, FreeRTOS, UDS, I2C, SPI, UART, CAN, PWM, ADC, DAC, and MATLAB State flow. A strong background in Field-Oriented Control (FOC) algorithm development for BLDC motors and AC motors is also essential. This role involves the design, development, and optimization of embedded motor control software for electric vehicle applications

Key Responsibilities

• Motor Controller Software Development - Design and develop embedded software for motor controllers used in electric vehicles (EVs). This includes integrating power electronics and motor control algorithms to ensure smooth and efficient motor operation
• Bootloader Development - Implement and optimize Bootloader for embedded motor controllers to manage firmware updates and system initialization in real-time
• FreeRTOS Integration - Utilize FreeRTOS to manage tasks, resource allocation, and real-time scheduling in the motor controller system, ensuring responsiveness and reliability under various load condition
• Control Algorithm Development - Develop and implement advanced Field-Oriented Control (FOC) algorithms for BLDC (Brushless DC) motors, AC motors, and other types of electric motors used in EVs. Optimize the algorithms for efficiency, power consumption, and performance
• Power Electronics Integration - Work closely with power electronics teams to integrate motor control systems with power circuits, including PWM (Pulse Width Modulation), ADC (Analog-to-Digital Conversion), and DAC (Digital-to-Analog Conversion) systems for precise motor control
• Protocol Implementation - Implement and manage communication protocols including I2C, SPI, UART, and CAN for intercommunication with sensors, actuators, and other embedded systems in the EV
• Unified Diagnostic Services (UDS) - Develop and implement UDS (ISO 14229) diagnostic protocols for fault detection, error handling, and communication between the motor controller and other ECUs (Electronic Control Units)
• Unit Testing & Validation - Design and implement unit testing strategies for motor control algorithms, communication protocols, and embedded software to ensure robustness, reliability, and compliance with safety and quality standards
• MATLAB/Simulink/State flow Modeling - Use MATLAB, Simulink, and State flow for modeling motor control systems, designing algorithms, performing simulations, and validating control logic
• System Integration and Optimization - Integrate the motor controller software with other vehicle control systems and optimize performance, ensuring seamless operation across various vehicle conditions (e.g., temperature variations, load changes, etc.)
• Documentation - Maintain detailed technical documentation including software architecture, algorithm design, system integration steps, test cases, and compliance reports to ensure full traceability and safety compliance
  
  

Ideal Candidate

• Education - Bachelor’s or Master’s degree in Electrical Engineering, Computer Science, Power Electronics, or a related field
• 3 to 6 years of experience in embedded software development for motor control systems, specifically in the electric vehicle (EV) domain.
• Proficiency in developing and optimizing Field-Oriented Control (FOC) algorithms for BLDC and AC motors
• Strong background in power electronics, including experience with PWM, ADC, and DAC for motor control applications
