Senior Electrical Serviceability Engineer in London

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 are looking for a Senior Electrical Serviceability Engineer to own the electrical and electronics dimension of serviceability for our humanoid robots. Product Services Engineering ensures the robot is designed to be maintained — modular, repairable, and serviceable at low skill in the field. You will own that mission for everything electrical: power distribution and batteries, wiring and harnesses, connectors, sensor and actuator drive electronics, and compute — including how faults are diagnosed, how systems are safely isolated, and how parts are replaced and reworked at the right BOM level.

This is a deeply technical, hands‑on role. You will validate the electrical and electronics dimension of every service procedure before production, define the diagnostic points and safe‑working practices that let our field and Repair Centre teams work quickly and safely, and act as part of the single engineering interface between Services and R&D.

What You’ll Do:

• Own Design-for-Serviceability for electrical and electronics: drive accessibility, connectorisation, safe isolation, and low‑skill field‑executability into the product before design is locked.
• Define and validate electrical repair, rework, and replacement procedures at the correct BOM level — module/assembly for the field, deeper for the Repair Centre — across power distribution, batteries, harnesses, sensor and actuator electronics, and compute.
• Specify the diagnostic points, test equipment, and safe‑isolation / lockout procedures needed to service the robot’s electrical systems safely and repeatably.
• Define the electrical diagnostic content in the Digital Shadow platform — localising power, sensing, and actuation faults as deep as possible in the BOM.
• Lead the electrical and electronics input to Service Failure Mode and Effects Analysis (S‑FMEA) and feed serviceability requirements back into design.
• Support New Services Introduction (NSI) for electrical scope, and act as the single point of entry from Services into R&D for electrical escalations.

We’re Looking For:

• Electrical or electronics engineering background with hands‑on experience diagnosing and repairing complex electromechanical products or robots.
• Strong grasp of power distribution, battery systems, wiring harnesses, connectors, sensors (LiDAR, cameras), and actuator drive electronics from a maintainability standpoint.
• Confident reading schematics and wiring diagrams, using electrical test equipment (multimeter, oscilloscope, and similar), and defining safe‑isolation and lockout/tagout procedures.
• Design-for-Serviceability experience: connectorisation, diagnostic access, fault isolation, and modularity of electrical assemblies.
• A field‑first, safety‑first mindset — you design for the technician who has limited time, tools, and training, and for whom electrical safety is paramount.
• Comfort working across the full BOM hierarchy, from full‑robot diagnosis to board‑ and component‑level repair.

Nice to have:

• Experience with humanoid or legged robotics electrical systems.
• Familiarity with battery management systems (BMS), high‑current power electronics, and functional‑safety considerations.
• Experience with calibration‑after‑repair for sensors and actuators.
• Exposure to spare‑parts / service‑replaceable‑unit (SRU) strategy and refurbishment loops.
• Experience introducing serviceability into a product moving from prototype to mass production.

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.
