## About Humanoid

Nos médias sont propulsés par une ambition : être leaders dans leur catégorie. Pour cela, nous donnons à nos rédactions toutes les armes pour faire du journalisme en ligne plébiscité, accessible gratuitement pour nos lectrices et nos lecteurs.

## About the role

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

As a Senior Prototype Engineer on the Core Platform team, you will rapidly iterate, assemble, diagnose, and evolve advanced robotic platforms for real-world use. In this hands-on role, you’ll drive results across the full hardware lifecycle—concepting, prototyping, root-cause analysis, documentation, and field repair—with a strong emphasis on reliability and repeatable processes.

### What You'll Do

- Lead troubleshooting and resolution of complex electrical issues in prototype humanoid robots, including operational and in-development systems; perform detailed failure analysis and share learnings with hardware/software engineering teams.

- Collaborate closely with multidisciplinary engineers on prototype design, assembly, and bring-up, especially high-density electromechanical integrations.

- Create, maintain, and execute clear test procedures, troubleshooting guides, and repair runbooks for the prototyping lab to ensure high standards and rapid iteration cycles.

- Design, document, and iterate on cable assemblies, test jigs, and harnesses optimized for repeated use on dynamic robotic platforms.

- Identify and own opportunities for continuous process and product improvement—minimizing downtime and improving test/repair efficiency.

- Contribute to robust feedback loops across design, build, and test, driving first-pass yield and manufacturability.

### What We're Looking For

- Demonstrated experience in rapid physical prototyping, hands-on debug of custom hardware, and troubleshooting complex electrical systems in robotics or similar domains.

- Working knowledge of low-voltage and mixed-signal circuits, connectors, sensors, and compact electromechanical systems.

- Track record communicating concisely via documentation—procedures, test plans, diagnostics, and lessons learned.

- Adept collaborating across mechanical, electrical, and software engineering boundaries to solve urgent, ambiguous issues.

- Comfortable in a high-velocity, high-ambiguity startup setting where priorities shift fast.

### Preferred

- Experience designing for manufacturability and reliability in the context of human-sized or mobile robotics.

- Familiarity with automated test and diagnostic tools used in modern hardware labs.

- Prior mentoring or technical leadership responsibility within a prototyping or field engineering team.

### 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.
