Embedded Firmware Engineer

About SF MOTORS, INC. (dba SERES)

SF Motors is building the next generation of intelligent robotic systems that combine advanced mobility, autonomy, and human-like adaptability. Our mission is to revolutionize how machines move, perceive, and interact in complex environments by integrating control engineering, artificial intelligence, and machine learning at every level of design.

Embedded Firmware Engineer

Duties and Responsibilities

• Develop and maintain firmware on STM32 / TI / Renesas MCU platforms
• Implement and debug low-level drivers (ADC, GPIO, PWM, SPI, I2C, UART, DMA, Timers)
• Support PCB bring-up, board validation, and hardware debugging
• Develop and optimize communication stacks (CAN, CANFD, Ethernet, Modbus, etc.)
• Write clean, maintainable C/C++ for real-time embedded systems
• Diagnose hardware and firmware integration issues
• Collaborate closely with hardware and controls engineers
• Develop internal tools and test scripts (Python preferred)
• Support firmware release cycles, regression testing, and documentation
• Contribute to code reviews and design discussions
• Design and implement firmware architectures that support scalable multi-actuator robotic systems
• Design command, state, telemetry, and fault-management abstractions for multi-joint robotic systems
• Define data models and interfaces for joint states, actuator feedback, control parameters, and real-time robot status
• Collaborate with controls and robotics engineers to translate motion-control requirements into stable firmware and SDK interfaces
• Support integration of SDK interfaces with higher-level robotics frameworks, simulation environments, and ROS/ROS2 when applicable
• Design unified motion-control APIs that abstract individual actuator communication and expose intuitive joint-level and whole-robot control interfaces to upper-layer applications
• Support kinematics-related data exchange and synchronization across distributed nodes
• Ensure deterministic timing and low-latency communication across robotic joints
• Participate in system-level debugging across firmware, SDK, and control layers
• Optimize performance for multi-joint coordination and synchronized actuation

Qualifications

• B.S. or M.S. in Computer Engineering, Electrical Engineering, or related field
• 1 – 3 years of embedded firmware experience
• Strong proficiency in C (C++ a plus)
• Hands-on experience with MCU peripherals and low-level driver development
• Experience with board bring-up and debugging tools (oscilloscope, logic analyzer, JTAG)
• Experience with real-time systems
• Basic understanding of industrial communication protocols
• Experience developing firmware for robotic systems, motor controllers, or multi-axis motion platforms
• Understanding of motor control fundamentals (FOC, PID control, current/velocity/position loops)
• Experience working with CAN-based multi-node robotic architectures
• Familiarity with ROS / ROS2 or robotics middleware is a plus
• Experience designing clean, stable SDK APIs for hardware abstraction
• Familiarity with CI/CD workflows for embedded systems
• Experience writing Python scripts for automation or testing preferred
• Comfortable working independently in a fast-paced environment
