Software Engineer – Motor Control & Embedded Systems

Location: Chennai, India

Department: Control Systems

Experience: 1 - 3

• Motor Control Algorithm Development
• Design and implement PMSM motor control algorithms (FOC, torque/regen strategies) in MATLAB/Simulink.
• Optimize models for real-time execution on embedded targets.
• Integrate algorithms with vehicle-level requirements such as regen profiles, drive cycles, and efficiency maps.
• Embedded Software Architecture
• Design and manage multi-rate cooperative schedulers for control tasks.
• Contribute to the migration toward RTOS-based architectures for scalability and robustness.
• Ensure deterministic timing and synchronization across control, comms, and diagnostic tasks.
• Microcontroller Selection & System Integration
• Collaborate with the hardware team to select appropriate microcontrollers.
• Define software requirements for clock speed, memory, peripherals, ADC resolution, PWM frequency, and comms interfaces (CAN, SPI, I2C, UART).
• Participate in pin mapping decisions to balance hardware constraints with software scheduling needs.
• Ensure MCU selection aligns with control-loop timing and future scalability.
• Communication & Integration
• Implement robust CAN communication, including message prioritization, diagnostics, and fault handling.
• Collaborate with hardware engineers on control signal mapping and sensor interfacing.
• Work with firmware engineers to integrate algorithms into embedded platforms.
• Vehicle-Level Perspective
• Conduct simulations that link motor control to vehicle performance (regen recovery, loss analysis, range impact).
• Tune strategies to balance drivability, efficiency, and thermal constraints.
• Contribute to higher-level functions such as traction control or torque-limiting logic.
• Testing & Validation
• Tune and validate controllers on dyno test benches and in-vehicle trials.
• Debug system-level issues that span across hardware, firmware, and software.
• Documentation
• Maintain control models, scheduling diagrams, and software architecture documentation.

Who Can Apply?

• B.E./B.Tech or M.E./M.Tech in Electrical, Electronics, Control Systems, or Computer Engineering.
• Strong expertise in MATLAB/Simulink for motor control algorithm design and deployment.
• Solid understanding of PMSM motor theory (FOC, torque/regen control, sensorless/sensored methods).
• Hands-on experience with embedded software design: task scheduling, cooperative schedulers, interrupt handling.
• Familiarity with RTOS concepts and migration strategies.
• Deep understanding of CAN communication (message arbitration, diagnostics, protocol layering).
• Experience collaborating on microcontroller selection and pin mapping with hardware engineers.
• Proven ability to tune and validate controllers in lab/dyno environments.

Nice-to-Have

• Proficiency in C/C++ for embedded targets.
• Familiarity with HIL testing or rapid prototyping.
• Exposure to AUTOSAR or advanced automotive comms stacks.
• Knowledge of functional safety (ISO 26262).

• Opportunity to work in a fast-paced and dynamic environment.
• Opportunities for professional advancement as the company undergoes expansion.
• A culture that fosters collaboration and creativity within the team.
• Collaborate closely with seasoned experts in the field.
