Software Engineer – Motor Control & Embedded Systems Job at Raptee Energy

Raptee is hiring for the role of Software Engineer – Motor Control & Embedded Systems!

Responsibilities of the Candidate:

• 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.
• 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.
• 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.
• 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.

Requirements:

• 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.
