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
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.
What We're Looking For
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.
What We Do
Fulfil has reimagined and reinvented online grocery automation with a completely unique, fully automated fulfillment system that enables customer-centric, sustainable and profitable online grocery at scale. Unlike legacy automation technology being tested for grocery fulfillment, Fulfil’s robots do all the picking and packing across all product categories and temperature zones, unlocking extreme speed, throughput, accuracy, and inventory control with minimal labor in a small footprint
