• Develop control strategies for challenging operating conditions including high starting torque, low-speed operation, stall, stall recovery, load transients,
• Analyze control-loop stability, dynamic response, system limitations, and performance margins
• Develop simulation and analytical models to support control design and system optimization
• Correlate control models and expected behavior with measured test data
• Tune and validate control performance using bench, dynamometer, hardware-in-the-loop, and system-level testing

System Integration

• Integrate embedded firmware and controls with power electronics, electric motors, sensors, actuators, and communication systems
• Work closely with electrical, power electronics, mechanical, systems, and test engineers to optimize overall system performance
• Define firmware and control requirements, interfaces, operating states, verification criteria, and V&V test cases
• Analyze system and test data, investigate failures, determine root causes, and implement corrective improvements
• Support design reviews, system integration, qualification, reliability testing, and product introduction

Required Qualifications

• Strong embedded C/C++ development experience for real-time systems
• Hands-on experience developing firmware on microcontrollers, DSPs, or similar embedded processors
• Strong understanding of embedded software architecture, interrupts, timers, ADCs, PWM, memory, peripheral interfaces, and real-time execution
• Strong understanding of feedback control systems and real-time control implementation
• Hands-on experience with PMSM, BLDC, or similar electric motor control
• Strong understanding of field-oriented control, current and torque regulation, speed control, PWM, and inverter operation
• Experience implementing and tuning control algorithms on embedded hardware
• Good understanding of electric machines, power electronics, sensors, signal conditioning, and embedded hardware interfaces
• Experience debugging integrated hardware, firmware, and control-system issues
• Ability to analyze measured data and translate test results into firmware and control improvements
• Strong system-level problem-solving skills and ability to work across firmware, controls, electronics, motors, and mechanical systems

Preferred Qualifications

• sensorless motor-control techniques and low-speed motor control
• MATLAB/Simulink or similar control modeling and simulation tools
• RTOS architecture and real-time scheduling
• hardware-in-the-loop and automated embedded-system testing
• bootloaders, firmware update mechanisms, diagnostics, and embedded data logging
• familiarity with software configuration management, code reviews, CI/CD, and embedded coding standards
• high-reliability, industrial, automotive, aerospace, energy, or other harsh-environment embedded systems
