Software that heals itself. Software that adapts to the user and the business. Software that learns and gets better as it’s used.\nOur starting point is finance. Companies including Legora, Lovable, and Fuse Energy already run on Light. We’re building towards a platform that understands how each business operates and evolves with it.\nAs an AI Engineering Intern, you’ll help make that happen: building systems that identify mistakes, improve their own behaviour, and prove those improvements work. You’ll work on the agents, models, and infrastructure that turn organic software into something customers can rely on.\nWho this is for\nYou must meet both of these requirements:\nCurrently studying at University of Oxford, or University of Cambridge.\n\nA silver medal or higher at the International Mathematical Olympiad (IMO) or International Olympiad in Informatics (IOI), or an equivalent level of achievement in another highly competitive endeavour.\n\nIf you’re applying with an equivalent achievement, explain the competition or field, your result, and the standard required to achieve it. If you’re at Oxford/Cambridge and you don’t have an equivalent level of achievement we encourage you to not apply.\nOur bar for internships at Light is high. You will need the curiosity to explore unfamiliar areas, the willingness to go the extra mile to get things right, the discipline to test your assumptions, and the persistence to keep going when your first approach does not work.\nWhat you’ll work on\nYou’ll have access to our repositories, real engineering problems, and an internal coding agent that already opens pull requests against production code. Your work will help make these systems more capable and reliable.\nHelp agents learn from their work. Our agent reviews merged pull requests and corrections to update its repository-specific instructions. You’ll shape that process, catch misleading lessons, and test whether new instructions improve its performance.\n\nTrain and deploy LLM and ML models. Fine-tune SoA LLM models. Run experiments, compare results against the existing pipeline, and establish whether a model is ready for production. Leverage ML tools to enhance the ability of our Agents via e.g. K-means, t-sne, PCA, random forest trees etc. etc.\n\nBuild Agents. Take full end to end ownership of an agent. Agent do pre-emptive support for the self-healing pipeline; they fix; they communicate with customers; etc.\n\nBuild evaluations and review tools. Define what a correct answer looks like, create tests that expose failures, and help catch poor output before it reaches customers.\n\nOwn projects through delivery. Scope the problem, build the solution, debug regressions, and follow through until the customer can rely on what you’ve shipped.\n\nYou’ll work alongside exceptional colleagues.\nWhat else we’re looking for\nStrong programming ability.\n\nSomething you’ve built beyond coursework or tutorials: a model, agent, tool, or application that does useful work.\n\nHands-on experience with AI tooling, such as LLM APIs, agent frameworks, model fine-tuning, or automated workflows.\n\nA habit of investigating why a system failed and testing whether your fix addresses the cause.\n\nClear thinking and the ability to explain your decisions, including what you tried and why it didn’t work.\n\nOpen-source contributions, deployed models, and experience building evaluation pipelines are a plus.\nHow we’ll measure success\nYour work should produce measurable improvements: more correct agent-generated changes, better model accuracy, fewer failures reaching users, or tools the team continues to use. You’ll help define those measures and use them to assess what you build.\nWhat you’ll get\nInternship compensation above the standard market rate.\n\nA role based in our London office, working alongside the product and engineering team.\n\nOwnership from your first day, with a path to shipping work into production.\n\nHow to apply\nSend your CV.\nInclude a link to something you’ve shipped. Tell us what it does, which parts you built yourself, where it failed, and how you fixed it. Then explain why you want to work on organic software at Light.\nWe want to understand how you think, what you can build, and what you’re ready to take on next.\nLight is an equal opportunity employer.","description_format":"text","description_chars":4403,"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":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Autonomous Driving","Computer Vision","Machine Vision & 3D Cameras"],"lifecycle":[{"event":"open","at":"2026-09-13T11:46:44Z"}],"visa":[],"liveness":{"score":65,"band":"ok","label":"Likely open","p_open":1,"p_active":0.897,"p_room":0.72,"age_days":47,"expected_fill_days":102,"reasons":["conf:1","velocity","win:mid","crowd:junior"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/light-ai-engineering-intern","json_url":"https://alion.io/job/light-ai-engineering-intern.json","meta":{"generated_at":"2026-10-31T06:24:38Z","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":9451,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"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":7310},"rest":"https://alion.io/mcp/rest/get_company?id=7310"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Flight-ai-engineering-intern"},{"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%2Flight-ai-engineering-intern"},{"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%2Flight-ai-engineering-intern"},{"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/light-ai-engineering-intern\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Flight-ai-engineering-intern"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":863674}},{"tool":"search_jobs","arguments":{"company":"light.co","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":863674},"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.
