Motor Control Firmware Engineer

Location: Chennai, India

Department: Control Systems

Experience: 3 - 5

Skills: Embedded Systems, Motor Drives, EV Powertrain

Role Overview:

What You’ll Do:

1. Develop and tune FOC algorithms: current regulation, MTPA, field weakening, and regenerative braking.
2. Implement SVM, PWM generation, and voltage limiting logic in embedded C for ARM Cortex-M targets.
3. Build and validate motor control models in MATLAB/Simulink; generate and verify production C code.
4. Integrate ADC-based current sensing, handle phase reconstruction, and calibrate sensor offsets.
5. Characterize and validate drive behavior across the full operating envelope on bench and motor Dyno.
6. Collaborate with hardware teams on inverter bring-up, gate driver integration, and fault protection.
7. Support vehicle-level integration: torque arbitration, state machine design, and diagnostics.

Who Can Apply?

1. 3–5+ years of hands-on motor control firmware experience with PMSM or BLDC drives.
2. Deep knowledge of FOC: Clarke/Park transforms, synchronous-frame PI control, and SVM.
3. Strong embedded C skills on ARM Cortex-M; comfortable with interrupt-driven, real-time architectures.
4. Experience with MATLAB/Simulink model-based design and embedded code generation.
5. Familiarity with ADC current sensing, real-time filtering, and signal conditioning.
6. Hands-on with oscilloscopes, runtime monitoring tools, and systematic firmware debugging.
7. B.E. / B.Tech or higher in Electrical, Electronics, or a related engineering discipline.

1. Experience with IPMSM saliency, reluctance torque exploitation, or MTPV operation.
2. Prior work on field weakening or regenerative braking in a production or near-production context.
3. Exposure to ISO 26262, MISRA-C, or automotive software quality processes.
4. Knowledge of EV power-train architecture, HIL simulation, or AUTOSAR.
