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

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
