OEMs have decade-long backlogs, new manufacturers are racing to market, and the industry is hundreds of thousands of technicians short.\nThe world needs more aerospace capacity, but the systems used to maintain and manufacture aircraft are slow, manual, and barely changed in decades. Fleetcraft is the full system to operate and manage aircraft maintenance. Our agents already work alongside technicians and controllers in 10+ maintenance organisations across 4 continents. They capture the repair as it happens and turn expertise into intelligence the whole operation can use.\nOur seed was led by Susa Ventures, alongside Liquid 2 VC, early backers of Anduril and Stoke Space. You'll work with a team that has helped launch airlines and put satellites into orbit, and with an aviation advisory board whose members have run major aircraft OEMs, led airworthiness at Gulfstream, and overseen training facilities that educate a quarter of all aircraft mechanics in the US.\nWhat you'll do\nYou'll build and scale the core systems aircraft technicians and planners use every day: deciding the architecture, writing the code, and sitting in the hangar watching people use it.\nBuild and scale the core systems that aircraft MROs rely on every day.\n\nBuild AI agent systems end-to-end, from voice interfaces on the hangar floor to workflow orchestration across maintenance operations.\n\nOwn projects from architecture to deployment, with autonomy over technical decisions.\n\nOwn reliability: infrastructure, observability, and evals for AI in a regulated industry.\n\nTurn aerospace data into trusted pipelines, from maintenance manuals and work orders to airworthiness directives and parts catalogues.\n\nStay at the frontier by adopting new model capabilities and improving the team's tooling.\n\nTalk to technicians, maintenance managers, and regulators, then turn what you learn into product decisions.\n\nWhat you'll need\n3+ years of full-stack experience.\n\nAbility to build high-quality software fast.\n\nA co-owner mindset. We'll give you the customer context and the autonomy to find the best path forward, and expect you to own the outcome.\n\nYou learn fast. Aerospace experience isn't required.\n\nYou're pragmatic and structured.\n\nStrong plus: Early-stage experience, competitive programming, trading, building agents.\nTech stack: FastAPI · Pydantic · TypeScript · React · OpenAI / Anthropic · PostgreSQL · Turbopuffer · Promptfoo · Azure\nWhat we offer\n£90k-£120k salary plus meaningful early-stage equity.\nModern tools, real-world impact in a regulated industry, and the chance to define how AI transforms aerospace from the ground up.\nWe are a small, high-trust team where your decisions move the whole company forward. If you're energised by building production AI systems that solve hard, real-world problems - and you want the ownership and pace that only comes from being early at something important, we'd love to talk.\nInterview process\nInitial screening interview with a co-founder (30 min)\n\nTechnical interview (75 min)\n\nIn-person interview and technical assessment (3 hrs)\n\nAfter the in-person meeting we check references and then make an offer.\nWe're unable to offer visa sponsorship for this role.\nFleetcraft is an equal opportunities employer.","description_format":"text","description_chars":3370,"description_truncated":false,"requirements":{"experience_years_min":3,"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":false,"industries":["AI Agents","Maintenance, Repair & Operations (MRO)","Industrial AI"],"lifecycle":[{"event":"open","at":"2026-11-09T14:53:26Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"adverts_offering_sponsorship_24m":0,"sanctioned_now":false,"evidence":"Licensed UK visa sponsor (Skilled Worker)","filings_12m":null,"filings_prev_12m":null,"green_card_filings_12m":null,"median_offered_wage_usd":null,"route":"Skilled Worker","cap_exempt":false,"checked_at":"2026-11-09T07:32:21+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":30,"reasons":["conf:1","win:early"],"computed_at":"2026-11-09T16:43:47Z"},"pay":{"stated_usd_annual":160283,"is_top_pay":false},"html_url":"https://alion.io/job/fleetcraft-software-engineer","json_url":"https://alion.io/job/fleetcraft-software-engineer.json","meta":{"generated_at":"2026-11-09T16:43:47Z","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":24534,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-10T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"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":676063},"rest":"https://alion.io/mcp/rest/get_company?id=676063"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Ffleetcraft-software-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":2,"usd":0.2},"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%2Ffleetcraft-software-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"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%2Ffleetcraft-software-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/fleetcraft-software-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Ffleetcraft-software-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3967656}},{"tool":"search_jobs","arguments":{"company":"fleetcraft.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3967656},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
