We're already delivering large-scale autonomous inspection programmes for National Grid and gaining traction with major grid operators internationally.\nWe're venture-backed and supported by Boeing, with a founding team whose backgrounds include Apple, CERN and McLaren F1.\nWe've solved some exceptionally hard problems in autonomy, aviation and regulation.\nNow we're solving the problems that come with scale, which creates some fascinating software challenges.\nHow do you turn autonomous flight into something that can operate at large scale?\nHow do you plan and manage increasing numbers of missions? How do you give operators the right information at the right moment? How do you handle the imagery, telemetry and flight records generated by every mission? And how do you turn all of that into structured information that infrastructure companies can actually use?\nThat's what our Cloud team is building.\nWe're looking for aSenior Full Stack Engineerto take ownership of significant parts of that platform.\nThe opportunity\nYou'll work across the stack, from the APIs, services and data models behind the platform, through to the interfaces used to plan and manage operations, review missions and work with the data captured in flight.\nYou'll be solving problems such as:\nDesign, build and ship full stack features in React and FastAPI, owning them from problem statement through to production and the feedback that comes back from operations.\n\nBuild the control room and customer-facing interfaces: mission planning, live operational views, post-process, review and sign-off of captured data.\n\nDevelop the services behind them: APIs, data pipelines and storage for large volumes of imagery, telemetry and flight records.\n\nMake the platform scale to continuous, concurrent operations across a national and international asset base.\n\nWork directly with flight operations, autonomy and customer teams to turn real operational problems into the simplest thing that solves them.\n\nRaise the engineering bar: testing, observability, CI/CD, code review, and the pragmatic architectural decisions that keep a small team fast.\n\nMake the best use of AI tooling, both for code development, review, but also in agentic data workflows\n\nWe're looking for someone who is genuinely comfortable across the stack rather than strongly front-end or back-end with limited experience on the other side.\nYou'll work directly with flight operations, autonomy engineers, inspection teams and customers. If you want to understand a problem, you can talk to the person experiencing it.\nBecause we're a relatively small engineering team, you'll also have real influence over what gets built, how it gets built and the technical decisions we make as we scale.\nWhat we're looking for\nYou'll have substantial commercial full-stack engineering experience and a track record of building high-quality production software.\nYou'll bring:\nStrong React and modern TypeScript\n\nStrong Python, ideally FastAPI\n\nGood API design and relational data modelling\n\nExperience with asynchronous systems\n\nExperience with cloud infrastructure, containers, CI/CD and monitoring\n\nExperience building systems that have scaled\n\nGood engineering judgement - knowing where rigour matters and where it's better to ship, learn and iterate\n\nAn ability to take an ambiguous problem, understand what users actually need and own the solution\n\nYou'll also be comfortable working with people who aren't software engineers. Here, that could mean pilots, aviation specialists, autonomy engineers and asset engineers.\nExperience with robotics, aviation, IoT, geospatial systems, real-time telemetry, large image or sensor datasets, AI/ML pipelines or safety-critical technologywould be useful, but isn't essential.\nWhy sees.ai?\nCompetitive salary and share options, you'll own a piece of what you build.\n\nA serious technical problem with a real-world result, in a company that has already proved the hard regulatory part.\n\nA small, senior team where your work is visible and your opinion counts\n\nWe offer competitive salary and share options, hybrid working across our London office and HQ near Chichester, and support for training, conferences and professional development.\nHow we hire\nAn introductory conversation about the role, sees.ai and what you're looking for.\n\nA technical conversation with the Cloud team about systems you've built and the decisions behind them.\n\nA practical exercise close to the actual work, discussed together rather than marked in isolation.\n\nA final conversation with the wider team and leadership.\n\nInterested?\nClick the “I’m interested” button to apply, or email our careers team on  if you would like a discussion before applying.","description_format":"text","description_chars":4975,"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":["Hybrid work","Professional development","Stock options"],"hiring_locations":[{"name":"United Kingdom","iso":"GB","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Drones & UAVs"],"lifecycle":[{"event":"open","at":"2026-10-07T11:52:20Z"}],"visa":[{"country":"GB","licensed_sponsor":true,"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":"2026-10-10T06:21:00+00:00","sources":["UK Home Office: register of licensed sponsors (workers)"],"filings_for_role_12m":0}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":30,"reasons":["conf:2","velocity","win:early"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/sees-senior-full-stack-engineer","json_url":"https://alion.io/job/sees-senior-full-stack-engineer.json","meta":{"generated_at":"2026-10-11T01:21:23Z","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","counted_by":"address","units_charged":1,"used_today":1999,"day_limit":5000,"remaining_today":3001,"minute_limit":60,"resets_at":"2026-10-12T00:00:00Z"}},"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":2293139},"rest":"https://alion.io/mcp/rest/get_company?id=2293139"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsees-senior-full-stack-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%2Fsees-senior-full-stack-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%2Fsees-senior-full-stack-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/sees-senior-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsees-senior-full-stack-engineer"}]}
