Key Responsibilities :

Firmware Development :

• Develop and optimize embedded firmware for motor control applications, including brushless DC (BLDC), PMSM, and AC induction motors.
• Implement motor control algorithms such as Field-Oriented Control (FOC) with efficient code that executes deterministically within microseconds.
• Perform complex mathematical computations using Control Law Accelerator (CLA) or similar processors.
• Write and debug firmware to support current calibration and encoder angle calibration processes.

Algorithm Design and Optimization :

• Design and implement calibration algorithms for current sensing and encoder angle alignment.
• Develop and refine motor control strategies for speed, torque, and position control.
• Optimize code for performance, accuracy, and reliability in real-time embedded systems.
• Collaborate with hardware engineers to define control system requirements and integrate firmware with hardware components.
• Test and validate motor control systems using oscilloscopes, logic analyzers, and motor dynamometers.

Testing and Validation :

• Conduct hardware-in-the-loop (HIL) testing and debugging of motor control systems. Validate system performance under varying operating conditions, including transient and fault scenarios.
• Document firmware functionality, testing procedures, and results.

Ideal Candidate :

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, or a related field.
• 3+ years of experience in embedded firmware development, focusing on motor control systems.
• Proficiency in C/C++ programming for real-time embedded systems.
• Experience with motor control techniques, including FOC, sensorless control, and PWM modulation.
• Strong understanding of microcontroller and DSP architectures, including ARM Cortex-M and TI C2000 series.
• Hands-on experience with current calibration, encoder angle calibration, and control parameter tuning.
• Knowledge of deterministic real-time programming, ensuring firmware execution within strict time constraints.
• Expertise in complex mathematical calculations, particularly using Control Law Accelerator (CLA) or similar hardware accelerators.
• Familiarity with communication protocols like CAN, SPI, UART, and I2C.
• Experience with MATLAB/Simulink and motor control development tools.
