A model that works in a notebook is not a feature that works for hundreds of millions of players, or a tool a game team trusts with their daily work. Help us Close that gap: the evaluation that tells you it's actually good, the latency and cost envelope that makes it viable, the failure modes you find before players do, and the plumbing that makes it boring to operate. We're not looking for someone who wants to train a frontier model. We're looking for someone who gets unreasonable results out of the ones that exist.\nWe are looking for someone to build and ship: AI features in live games, and the internal tools that give superpowers to Supercellians. Some of that work will take you inside a game or central team for a while, close enough to their craft to build the right thing with them.\nIn our team, you'll work closely with our AI Platform Engineers, AI/ML engineers, Clients Programmers, Cloud Engineers. You’ll also collaborate with other teams including Data, QA, Engine and game teams.\nWhat You'll Be Doing\nBuild and ship AI features and systems end to end into live games and internal tools, at production quality and under real deadlines.\n\nDo the applied engineering that makes AI work in practice.\n\nOwn evaluation as a first-class deliverable. Write and maintain the benchmarks, evals, and regression suites that tell you whether something is genuinely good, across the modalities you're working in.\n\nFine-tune, adapt, and distill models where it pays off, and have the judgment to know when a better prompt, better retrieval, or a smaller model beats training anything.\n\nMake sound trade-offs on inference, including on-device where it matters, against real parameter, latency, and battery targets, without losing the feel players expect.\n\nTake on the harder applied problems, such as making autonomous agents reliable and accurate enough to trust with real work.\n\nWork close to game and central teams, sometimes embedded with them for a stretch, and build things that stay in use after you move on.\n\nMentor our more junior AI/ML engineers through code review, pairing, and design discussion, and raise the technical bar around you.\n\nStay at the frontier by reading the literature and following the major conferences, and bring back what is genuinely useful.\n\nWhat You Have\nStrong, current command of modern generative methods at the applied level: you know what today's models are actually good at, where they break, and how to build reliably on top of them.\n\nA track record of shipping LLM or generative AI applications that real users used, in production, not prototypes. We value this far above a publication record.\n\nReal software engineering depth. You write code others can maintain, and you own things in production rather than handing them off.\n\nHands-on experience writing and maintaining benchmarks and evaluation frameworks, ideally across more than one modality.\n\nPractical fine-tuning and model adaptation experience, and the judgment to know when not to reach for it.\n\nSound judgment on inference trade-offs under tight compute, latency, and cost constraints, including local or on-device deployment.\n\nThe ability to work from broadly defined goals, set your own objectives, and drive work forward without waiting to be handed a spec.\n\nHigh EQ and credibility with makers. You can sit inside a protective, high-craft team and earn their trust fast.\n\nA generous mentor to less experienced engineers, with high ownership, comfort taking risks and learning from failure, and the humility to do excellent work with kindness.\n\nWould Be Nice if You Also Have\nExperience with agent frameworks, orchestration, or evaluation tooling at production scale.\n\nGame industry experience, or a real appreciation for mobile.\n\nExperience working alongside a platform or infrastructure team as an internal customer.\n\nWhere You'll Be\nThe role requires close collaboration with the other central teams and game teams, so ideally, you'd be based in Helsinki.\nThat's it about the role! Below, we've gathered some things we feel are important for you to know. Totally optional, but a highly recommended read. \nOnce you're ready to apply, just send us your application through the form on the bottom of the page. \n---\nAbout Supercell\nSupercell is a games company from Helsinki, Finland, with offices also in San Francisco, Seoul, Shanghai, and London. You might know us as the makers of Hay Day, Clash of Clans, Boom Beach, Clash Royale, and Brawl Stars. Our mission is to create great games that as many people as possible play for years and that are remembered forever.\nSo, how do we make great games? By putting together the best teams and giving them the freedom and independence to succeed. And by taking risks, failing, sharing learnings, and killing lots of projects.\nHey, You Might Love It Here!\nIndependent cells and trust are at the core of our culture. But it takes more than that to make great games. We take good care of our people, providing them with the compensation, work environment, and resources they need to succeed while having fun along the way.\nYou Are Not Your Job Title ™\nHere, you won’t need to focus on chasing titles or climbing ladders. Internally, our job titles don’t include prefixes like Senior, Junior, Principal, or Director. Recognition isn’t tied to your title, as it doesn't define the impact you can have around here.\nBenefits and Compensation\nLuring you in with glitter, glamour, and gems isn't what we're about. We want you to enjoy your time here fully, so we structure our compensation and benefits with that in mind. It starts with perceiving you as a human being, not a resource.\nRelocation? Yes!\nNo matter where you’re moving from, our dedicated mobility team and partners will support you throughout your move. We’ll ensure the process is as smooth as possible for you and anyone joining you - whether they’re family members of the human or animal kind!\nNot Sure if You Should Apply?\nMany candidates with great skills and experience second-guess themselves. The bar is high, but if this role excites you, apply! We’re here to help you succeed. Also, we're happy to learn about any specific accommodations you may need to fully engage in our recruitment process.\nWishing you all the best,\nThe Supercell Recruitment team","description_format":"text","description_chars":6587,"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":true,"industries":["Mobile Games"],"lifecycle":[{"event":"open","at":"2026-10-14T09:22:39Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":2,"expected_fill_days":104,"reasons":["conf:3","velocity","win:early"],"computed_at":"2026-10-16T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/supercell-aiml-engineer","json_url":"https://alion.io/job/supercell-aiml-engineer.json","meta":{"generated_at":"2026-10-16T23:35:51Z","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":5585,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-17T00:00:00Z"}},"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":52311},"rest":"https://alion.io/mcp/rest/get_company?id=52311"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fsupercell-aiml-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%2Fsupercell-aiml-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%2Fsupercell-aiml-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/supercell-aiml-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fsupercell-aiml-engineer"}]}
