About the Role

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.

What You'll Do

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.

Required

• 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

Preferred

• Exposure to gRPC and Protobuf interfaces
• Experience with motion control, encoder feedback, or motor tuning
• Familiarity with build systems such as Bazel or CMake
• Experience with version control and CI/CD practices for firmware
• A maker or tinkerer background — robotics competitions, hobby electronics, hardware hacking

Why Fulfil

Real‑world impact from day one. Your code runs on real robots in production environments. The work is concrete and the feedback loop is short.

A genuinely cross‑disciplinary environment. Our teams span mechanical design, software, computer vision, systems integration, and ops. You'll collaborate across all of them.

Compensation that reflects the role. $140,000 base salary, equity, and competitive medical, dental, and vision coverage plus 401K, life, and disability.

A culture that respects your time. We encourage and expect everyone to take time away. Work‑life balance is something we actively protect.
