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 - our rapidly developed humanoid platform being deployed in real industrial environments - and we’re growing the team to take it even further.\nAbout the Role\nAs 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.\nWhat You'll Do\nLead 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.\n\nCollaborate closely with multidisciplinary engineers on prototype design, assembly, and bring-up, especially high-density electromechanical integrations.\n\nCreate, maintain, and execute clear test procedures, troubleshooting guides, and repair runbooks for the prototyping lab to ensure high standards and rapid iteration cycles.\n\nDesign, document, and iterate on cable assemblies, test jigs, and harnesses optimized for repeated use on dynamic robotic platforms.\n\nIdentify and own opportunities for continuous process and product improvement minimizing downtime and improving test/repair efficiency.\n\nContribute to robust feedback loops across design, build, and test, driving first-pass yield and manufacturability.\n\nWhat We're Looking For\nDemonstrated experience in rapid physical prototyping, hands-on debug of custom hardware, and troubleshooting complex electrical systems in robotics or similar domains.\n\nWorking knowledge of low-voltage and mixed-signal circuits, connectors, sensors, and compact electromechanical systems.\n\nTrack record communicating concisely via documentation procedures, test plans, diagnostics, and lessons learned.\n\nAdept collaborating across mechanical, electrical, and software engineering boundaries to solve urgent, ambiguous issues.\n\nComfortable in a high-velocity, high-ambiguity startup setting where priorities shift fast.\n\nPreferred\nExperience designing for manufacturability and reliability in the context of human-sized or mobile robotics.\n\nFamiliarity with automated test and diagnostic tools used in modern hardware labs.\n\nPrior mentoring or technical leadership responsibility within a prototyping or field engineering team.\n\nWhat We Offer\nCompetitive equity: stock options with meaningful upside as we scale.\n\n30+ paid days off, including 23 days of annual leave, all UK bank holidays, and additional company closure days (including Christmas-New Year shutdown).\n\nPrivate healthcare, including virtual and in-person care.\n\nPension scheme with 8% total contribution (5% employee, 3% employer) on full earnings.\n\nFree daily breakfast, catered lunch, and snacks in-office.\n\nWork at the frontier: collaborate daily with world-class engineers, researchers, and product experts building the next generation of AI and humanoid robotics.\n\nReal ownership - direct access to founding leadership, meaningful input on product direction, and the ability to drive key initiatives from day one.","description_format":"text","description_chars":3472,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Annual leave","Equity","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Robotics AI","Logistics & Warehouse Robotics","Industrial Robotics","Humanoid Robots"],"lifecycle":[{"event":"open","at":"2026-09-05T10:34:46Z"}],"visa":[],"liveness":{"score":31,"band":"fade","label":"Fading","p_open":1,"p_active":0.57,"p_room":0.55,"age_days":60,"expected_fill_days":58,"reasons":["conf:0","stale_co","velocity","win:tail"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/humanoid-senior-prototype-engineer","json_url":"https://alion.io/job/humanoid-senior-prototype-engineer.json","meta":{"generated_at":"2026-10-17T06:41:33Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":9115,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":35230},"rest":"https://alion.io/mcp/rest/get_company?id=35230"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fhumanoid-senior-prototype-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fhumanoid-senior-prototype-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fhumanoid-senior-prototype-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/humanoid-senior-prototype-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhumanoid-senior-prototype-engineer"}]}
