Hardware Integration and Development Engineer

Here at Humanoid, we believe in a future where robots amplify human potential. That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND‑01 Alpha - our rapidly developed humanoid platform now running in real industrial pilots - and we’re growing the team to take it even further. ABOUT THE ROLE We're looking for a Hardware Integration and Development Engineer to bring up, integrate and validate the electronics behind the end effectors on our robots and the human-worn devices operators use to interface with them. You'll focus on getting hardware working reliably end-to-end — integrating sensors, compute platforms and PCBAs, debugging issues at the boundary of electrical, mechanical and firmware, and supporting test and validation — in a high-paced environment where priorities shift fast. WHAT YOU'LL DO - Bring Up New Hardware: Bring up new PCB/PCBA revisions — reviewing schematics, checking power rails, and debugging with an oscilloscope and logic analyzer. - Integrate Sensors & Platforms: Integrate sensors, encoders, cameras and IMUs with compute platforms such as ESP32, Raspberry Pi and NVIDIA Jetson into working hardware assemblies. - Validate Communication Interfaces: Verify and debug communication interfaces between subsystems, including I2C, SPI, UART, Ethernet, USB, CAN, EtherCAT and MIPI. - Own Calibration & Diagnostics: Develop and run calibration routines, diagnostic tooling and fault/status checks across integrated hardware. - Support Component Selection: Help evaluate and select sensors, MCUs and other hardware building blocks alongside electrical and mechanical engineers. - Cross-Discipline Debugging: Resolve integration issues that span firmware, electrical and mechanical, working closely with all three teams. - Support Test & Validation: Support hardware test rigs, trials and validation activities, providing hands-on troubleshooting. - Document Interfaces: Document hardware interfaces, bring-up procedures and known issues clearly for other engineers to build against. WHAT WE'RE LOOKING FOR - Degree in Electrical/Computer Engineering or a related field, with 4+ years' experience in hardware integration, bring-up or embedded systems roles. - FPGA experience is required. - Hands-on experience integrating and debugging sensors, encoders, cameras and compute platforms such as ESP32, Raspberry Pi or NVIDIA Jetson. - Solid understanding of communication and sensor interfaces: I2C, SPI, MIPI, UART, Ethernet, USB, CAN and EtherCAT. - Strong hardware debugging skills — oscilloscope, logic analyzer, JTAG/SWD — and comfort bringing up new PCB/PCBA revisions. - Experience developing calibration routines and supporting hardware test/validation activities. - Comfortable working across firmware, electrical and mechanical boundaries in a high-paced environment. NICE TO HAVE - Basic embedded firmware or scripting experience for tooling and diagnostics - Experience working with formally defined hardware interfaces/contracts shared across teams - Experience in a robotics or hardware startup environment WHAT WE OFFER - Competitive equity: stock options with meaningful upside as we scale. - 30+ paid days off, including 23 days of annual leave, all UK bank holidays, and additional company closure days (including Christmas–New Year shutdown). - Private healthcare, including virtual and in-person care. - Pension scheme with 8% total contribution (5% employee, 3% employer) on full earnings. - Free daily breakfast, catered lunch, and snacks in-office. - Work at the frontier - collaborate daily with world-class engineers, researchers, and product experts building the next generation of AI and humanoid robotics. - Real ownership - direct access to founding leadership, meaningful input on product direction, and the ability to drive key initiatives from day one.
