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\nWe're looking for a hands-on Prototype Engineer to build, assemble and maintain hardware prototypes for the end effectors on our robots and the human-worn devices operators use to interface with them. You'll run our prototyping shop, build and maintain test rigs, and support hardware testing and trial sessions - turning CAD files and BOMs into working units, fast. This is a high-paced environment where turnaround is tight and your work directly shapes what the design team builds next.\nWhat You'll Do\nBuild Prototype Hardware: Build, assemble and maintain prototype hardware from CAD/BOM through to working units.\n\nOperate Workshop Equipment: Operate 3D printers, CNC and general workshop tools to produce prototype parts quickly and to spec.\n\nPrototype with MCUs: Quickly wire up and prototype with MCU platforms such as ESP32 and Raspberry Pi to support test rigs and hardware validation.\n\nBuild & Run Test Rigs: Build, set up and run test rigs and validation jigs for durability, calibration and functional testing.\n\nSupport Hardware Testing: Support hardware testing, internal trials and demo sessions, providing hands-on troubleshooting and repair.\n\nTurn Around Fast: Deliver prototype builds within tight timelines to keep pace with rapid design-iteration cycles.\n\nManage the Shop: Maintain an organised prototyping shop and parts inventory, including fasteners, connectors and components.\n\nFeed Back to Design: Document build issues and feed practical build, assembly and serviceability feedback directly into design decisions.\n\nWhat We're Looking For\nBackground in mechanical/mechatronic engineering, technician training, or equivalent hands-on hardware experience, with 2-4 years' experience prototyping physical hardware or robotics products.\n\nPractical skills with 3D printing, hand tools, basic machining, soldering and cable/harness assembly.\n\nAbility to prototype quickly with MCU platforms (e.g. ESP32, Raspberry Pi and similar), plus basic breadboarding and circuit assembly skills.\n\nComfortable reading CAD drawings and BOMs and translating them into a physical build; any level of CAD design capability is a plus.\n\nExperience building test rigs and supporting hardware testing, trials or demos of prototype hardware.\n\nA practical, get-it-working mindset with good organisational habits, comfortable in a high-paced, iterative environment. Nice to have\nAny level of CAD design capability - not just reading drawings, but creating or modifying simple parts/fixtures\n\nBasic electronics debugging skills (multimeter, continuity checks, simple rework)\n\nExperience assembling wearable or compact electromechanical devices\n\nExperience in a robotics or hardware startup lab environment\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":3864,"description_truncated":false,"requirements":{"experience_years_min":2,"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":29,"band":"fade","label":"Fading","p_open":1,"p_active":0.532,"p_room":0.55,"age_days":60,"expected_fill_days":58,"reasons":["conf:0","stale_co","velocity","win:tail","comp:junior"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/humanoid-prototype-engineer","json_url":"https://alion.io/job/humanoid-prototype-engineer.json","meta":{"generated_at":"2026-10-17T13:29:23Z","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":18140,"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-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-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-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-prototype-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fhumanoid-prototype-engineer"}]}
