Embedded Firmware & Controls Engineer to develop embedded software and control solutions for high-performance electromechanical systems operating in demanding environments. The role requires strong capability in both real-time embedded firmware development and motor/control-system engineering, with responsibility from algorithm development through implementation, integration, and validation.
Key Responsibilities
Embedded Firmware
- Develop real-time embedded firmware in C/C++ on microcontrollers, DSPs, or similar embedded platforms
- Develop firmware architecture, hardware abstraction layers, device drivers, and peripheral interfaces
- Implement task scheduling, state machines, diagnostics, fault handling, protection, and recovery logic
- Develop and integrate communication interfaces and protocols including CAN, SPI, I2C, UART, RS-485, or similar
- Work with RTOS-based and bare-metal embedded systems
- Develop configuration, calibration, data logging, boot, and firmware update functionality
- Develop unit and integration tests and support structured firmware verification and validation
- Debug hardware and firmware using debuggers, oscilloscopes, logic analyzers, protocol analyzers, and other laboratory equipment
Controls
- Develop, implement, and tune real-time control algorithms for electric motor drive and electromechanical systems
- Implement field-oriented control, current regulation, torque control, speed control, PWM, and related motor-control functions
- Develop startup and sensorless control methods and robust transitions between control modes
- 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
