Robotics Firmware Engineer, Fulfil Solutions

• Located within commuting distance of Mountain View, CA
• 2–4 years of experience in embedded firmware development
• Solid C and C++ skills in an embedded Linux environment
• Working knowledge of embedded communication protocols: CAN, I2C, SPI, UART, or Modbus
• Experience with hardware debugging tools (oscilloscope, logic analyzer, multimeter)
• Familiarity with Linux-based SBCs (Raspberry Pi, NXP i.MX, or similar)
• BS in Computer Science, Electrical Engineering, or equivalent practical experience
• Exposure to gRPC and Protobuf interfaces

Desirable

• Fulfil is looking for a Firmware Engineer to join our Embedded Systems team
• You'll work on the low-level software that drives our custom robotics hardware — implementing protocols, building control logic, and helping bring new hardware to life in a fast-moving production environment
• This is a hands-on individual contributor role
• You'll work closely with senior engineers and cross-functional teammates in hardware, software, and systems integration to implement firmware that is reliable, testable, and built to last
• Firmware Development Implement robust firmware in C/C++ for ARM-based microcontrollers and Linux-based SBCs. Develop and maintain protocol implementations across CAN bus, I2C, UART, SPI, and Modbus
• Hardware Integration Participate in bring-up and validation of custom hardware. Use oscilloscopes, logic analyzers, and multimeters to debug at the hardware/firmware boundary
• Motion & Control Implement motor control sequences including encoder-based positioning, tuning, and jerk limiting under the guidance of senior engineers
• Interface Development Work with gRPC and Protocol Buffer interfaces to expose hardware services to higher-level systems cleanly and safely
• Testing & Quality Write unit tests and contribute to HIL (Hardware-in-the-Loop) test environments. Debug issues across firmware logic, sensor integration, and timing
• Cross-Functional Collaboration Work with hardware, software, and systems teams to understand interface contracts and align on firmware behavior
