Firmware Engineer

Contract Firmware Engineer (Embedded Motor Control)

Contract | Remote/Hybrid | Project-Based

BlackBox Motor Systems is seeking an experienced Embedded Firmware Engineer to assist with the development of next-generation integrated motor control systems. This is a contract position for a specific development project with the potential for future work.

Responsibilities

• Develop embedded firmware for STM32-based motor controllers
• Implement and optimize FOC (Field-Oriented Control) algorithms for BLDC/PMSM motors
• Develop communication interfaces including CAN/CANopen, Ethernet, and Modbus RTU (RS-485)
• Interface with magnetic encoders, sensors, and power electronics
• Test, debug, and validate firmware on development hardware
• Collaborate with our engineering team through regular design reviews and project updates

Preferred Qualifications

• Strong embedded C/C++ programming experience
• Experience with STM32 or similar ARM Cortex-M microcontrollers
• Experience implementing FOC motor control
• Experience with CAN, Ethernet/TCP-IP, and Modbus RTU
• Familiarity with PWM generation, ADCs, timers, DMA, and real-time embedded systems

Work Arrangement

• Remote work is acceptable.
• Candidates should have access to a basic embedded development equipment capable of firmware testing and debugging (oscilloscope, power supply, programmer/debugger, and similar equipment).
• Development hardware will be provided as needed.

If you have experience developing high-performance motor control firmware and enjoy solving challenging embedded systems problems, we'd like to hear from you.
