Senior In-House Repair Technician 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 In-House Repair Technician with the deepest hands‑on repair capability in our Services Repair Centre. You will perform complex repair, rework, and full overhaul/restore on parts, sub-systems, and full robots, and deliver approved upgrades to existing units. You will also be our forensic‑analysis specialist, determining root cause and supporting warranty decisions in both directions. This is a senior, hands‑on role. You will act as a “flying doctor” at customer sites for the most difficult interventions, help author the work instructions the rest of the team follows, and mentor Associate and Advanced technicians.

What You’ll Do:

• Perform complex repair, rework, and full overhaul/restore on parts (SRUs), sub-systems, and full robots.
• Deliver approved upgrades to existing robots and parts.
• Lead physical troubleshooting and forensic analysis when Remote Services cannot localise a fault, determining root cause and supporting warranty determination (supplier claims, proof a fault was not caused by Humanoid…).
• Act as a flying doctor at customer sites for the most difficult on‑site interventions.
• Partner with Product Services Engineering and the Training team to author clear, low‑skill work instructions.
• Mentor Associate and Advanced technicians and contribute to the skills matrix and the unified career path across In‑House, Remote, and Field roles.
• Own refurbishment throughput and quality for the most complex part families, and certify work to specification.

We’re Looking For:

• Mechanical/electrical technician training plus ~5+ years of hands‑on repair experience, with deep specialisation.
• Proven ability to overhaul and restore complex electromechanical systems and full robots to specification.
• Strong forensic troubleshooting skills — you find root cause and can defend a warranty determination with evidence.
• Ability to author work instructions and mentor other technicians.
• Rigorous quality, certification, 5S and health‑and‑safety discipline.
• Willingness to travel for on‑site interventions.

Nice to have:

• Experience with humanoid, legged, or advanced robotics hardware.
• Familiarity with calibration, metrology, and test/certification requirements for precision mechatronics.
• Exposure to failure‑analysis methods and supplier‑quality / warranty processes.
• Experience setting up or scaling a repair or refurbishment operation.

What We Offer

• Competitive equity: stock options with meaningful upside as we scale.
• 30+ days off, including 23 days 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.
