Robotics firmware Engineer II

Fulfil Solutions•Mountain View, CA

10h•Onsite

About The Position

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.

Requirements

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

Nice To Haves

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

Responsibilities

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.
Participate in bring-up and validation of custom hardware.
Use oscilloscopes, logic analyzers, and multimeters to debug at the hardware/firmware boundary.
Implement motor control sequences including encoder-based positioning, tuning, and jerk limiting under the guidance of senior engineers.
Work with gRPC and Protocol Buffer interfaces to expose hardware services to higher-level systems cleanly and safely.
Write unit tests and contribute to HIL (Hardware-in-the-Loop) test environments.
Debug issues across firmware logic, sensor integration, and timing.
Work with hardware, software, and systems teams to understand interface contracts and align on firmware behavior.
