This is a deeply hands-on engineering role, not a project management or people management position: you'll work across Mechanical Engineering, Electronics, Embedded Software and Flight Test to ensure complete UAV systems are integrated, debugged, validated and ready for flight, combining practical engineering with technical leadership of prototype execution.\nThe day-to-day\nOwn the transition from subsystem designs to complete, flight-ready prototypes.\nLead prototype integration, hardware bring-up and multidisciplinary debugging - catching integration issues before they become flight test problems.\nStay hands-on across disciplines: PCB modifications, interface boards and wiring harnesses; mechanical prototype components and fixtures; hardware debugging, assembly, rework and rapid prototyping; and embedded bring-up and validation where required.\nAct as the primary Hardware Engineering interface to Flight Test - preparing aircraft for testing, making sure tests answer the right engineering questions, supporting investigation of hardware issues, and driving engineering improvements from the results.\nBuild tools and methods that improve hardware development, including board validation firmware, test automation, manufacturing and EOL test solutions, and engineering utilities and instrumentation.\nOwn the technical execution of integrating mechanical, electronics, embedded and systems work into validated, flight-ready hardware, so specialist engineers can stay focused on their own disciplines.\nYou should apply if you\nHave hands-on experience integrating mechanical, electronics and embedded subsystems into working hardware - in aerospace, robotics, automotive or another hardware-intensive field.\nAre comfortable debugging across disciplines, from PCB and wiring issues to mechanical fit and embedded bring-up, rather than staying within a single specialism.\nHave experience preparing hardware for test (bench, flight or field) and turning test results into concrete engineering fixes.\nCan build your own tools and test infrastructure - firmware, automation, fixtures - rather than relying on others to provide them.\nWant a deeply hands-on engineering role, not a project or people management position.\nCommunicate well across engineering disciplines and can work effectively with specialist teams without owning their subsystem designs.\nNice to haves\nPrior experience integrating hardware for UAVs or other flight-critical systems.\nExperience building test automation, board validation firmware, or end-of-line (EOL) test tooling.\nComfortable acting as the bridge between mechanical and electrical engineering - translating between the two disciplines and driving that collaboration through to a working prototype.\nWhat we offer\nReal impact & ownership:Shape high-tech defense systems and take responsibility from day one.\nMission-driven environment: Work on technologies that matter for European security and sovereignty.\nCompetitive package:Competitive salary, EGYM Wellpass, corporate benefits, and equity options aligned with role and level.\nDeep tech environment:Get hands-on experience with cutting-edge drone technology and real operational use cases.\nGrow fast: Steep learning curve for juniors, strategic influence and leadership opportunities for seniors.\nStartup mindset meets defence innovation:flat hierarchies, fast decisions, and space for your ideas.\nFlexibility:Flexible hours, remote options, and relocation support.\nStrong team:International, driven colleagues and a culture built on exchange, trust, and shared success.","description_format":"text","description_chars":3831,"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":["Equity"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":true,"industries":[],"lifecycle":[{"event":"open","at":"2026-10-04T21:30:22Z"}],"visa":[],"liveness":{"score":7,"band":"cold","label":"Long shot","p_open":1,"p_active":0.204,"p_room":0.35,"age_days":51,"expected_fill_days":6,"reasons":["conf:1","win:tail"],"computed_at":"2026-10-23T05:54:15Z"},"pay":null,"html_url":"https://alion.io/job/twentyfour-industries-senior-hardware-integration-engineer","json_url":"https://alion.io/job/twentyfour-industries-senior-hardware-integration-engineer.json","meta":{"generated_at":"2026-10-23T17:16:08Z","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":26222,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-24T00:00:00Z"}},"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":3894744},"rest":"https://alion.io/mcp/rest/get_company?id=3894744"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ftwentyfour-industries-senior-hardware-integration-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%2Ftwentyfour-industries-senior-hardware-integration-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%2Ftwentyfour-industries-senior-hardware-integration-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/twentyfour-industries-senior-hardware-integration-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ftwentyfour-industries-senior-hardware-integration-engineer"}]}
