Job Description

Fulfil is a well-funded, rapidly growing, and inclusive company that has developed a custom automation robotics system to pick and pack online orders of groceries and other consumables, bringing delight and a value proposition to consumers that doesn’t exist today. Additionally, its unique design and technology is purpose-built to solve today’s environmental problems in the world’s food supply chain. Founded by a team with previous startup success and backed by top-tier VCs, we are committed to reducing waste, improving environmental impact, and reducing emissions with truly new technology. We can’t do it alone -- we’re seeking curious, capable, passionate team members motivated by the opportunity to create lasting impact on the world through their work. This role offers ample growth opportunities while working side-by-side with an impassioned, multi-disciplinary team spanning mechanical design, software, computer vision, systems integration, and ops to design and operationalize world-changing technology. Fulfil is committed to creating an inclusive culture, and we celebrate diversity of all kinds.  If this sounds like the kind of environment that you find intriguing, then please apply even if you don’t feel you meet all the requirements listed below.  We'd love to hear from you. Company: Fulfil Solutions Location: Mountain View, CA (On-site) Team: Firmware / Embedded Systems Compensation: $140,000 base salary + equity + benefits   <h2 class="font-claude-response-body break-words whitespace-normal leading-[1.7]">About the Role</h2> 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.   <h2 class="font-claude-response-body break-words whitespace-normal leading-[1.7]">What You'll Do</h2> 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.   <h2 class="font-claude-response-body break-words whitespace-normal leading-[1.7]">What We're Looking For</h2> Required <ul class="[li_&]:mb-0 [li_&]:mt-1 [li_&]:gap-1 [&:not(:last-child)_ul]:pb-1 [&:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="whitespace-normal break-words pl-2">Located within commuting distance of Mountain View, CA</li> <li class="whitespace-normal break-words pl-2">2–4 years of experience in embedded firmware development</li> <li class="whitespace-normal break-words pl-2">Solid C and C++ skills in an embedded Linux environment</li> <li class="whitespace-normal break-words pl-2">Working knowledge of embedded communication protocols: CAN, I2C, SPI, UART, or Modbus</li> <li class="whitespace-normal break-words pl-2">Experience with hardware debugging tools (oscilloscope, logic analyzer, multimeter)</li> <li class="whitespace-normal break-words pl-2">Familiarity with Linux-based SBCs (Raspberry Pi, NXP i.MX, or similar)</li> <li class="whitespace-normal break-words pl-2">BS in Computer Science, Electrical Engineering, or equivalent practical experience</li> </ul> Preferred <ul class="[li_&]:mb-0 [li_&]:mt-1 [li_&]:gap-1 [&:not(:last-child)_ul]:pb-1 [&:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="whitespace-normal break-words pl-2">Exposure to gRPC and Protobuf interfaces</li> <li class="whitespace-normal break-words pl-2">Experience with motion control, encoder feedback, or motor tuning</li> <li class="whitespace-normal break-words pl-2">Familiarity with build systems such as Bazel or CMake</li> <li class="whitespace-normal break-words pl-2">Experience with version control and CI/CD practices for firmware</li> <li class="whitespace-normal break-words pl-2">A maker or tinkerer background — robotics competitions, hobby electronics, hardware hacking</li> </ul>   <h2 class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Why Fulfil</h2> 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.
