Not for a six-month appointment. Not for a system to catch up. But that’s exactly how healthcare works today. You wait, until you can’t.\nAlan exists to end the wait.\nHealth is a universal right, and we believe this right can only become real when it’s coupled with prevention. We need to stop treating health as something we repair and start treating it as something we build, every day. It’s not solely a question of willpower. It’s the healthcare system itself that needs to work for everyone, in a sustainable way.\nSo we are building thenew standard in prevention insurance. Alan is the first company that integrates insurance, prevention, and care into a single, acclaimed user experience.\nWe are on an incredible journey to build a global leading company, with aunique culture. We already partner with 40K+ companies of all sizes, serving more than 1M+ members, and have reached €800M+ in ARR.\nPrevention as the new norm. That's what we're building with our team of 1000+ people. If it speaks to you: we're hiring across France, Spain, Belgium, and Canada. And beyond.\nWhat you'll build and who you'll work with\nEvery Alan product, in every country, runs on the same backend: events, queues, cache, data shared between components, transactions. More than 200 engineers build on it every day. It carries more than 1 million members today. It must carry 10 million, in more countries, with more regulated health data.\nYou would join Backend Platform, a new team in our engineering organisation. Our job is to rethink the backend of a fully grown company, while it keeps running. Today almost everything runs in one Python monolith on one database. We are moving it towards big services that scale on their own, one pilot at a time. We build the tools that make this possible, and we set the rules for how Alan builds backends.\nThis is a rare kind of project. The codebase serves real members and customers every day, and we have the mandate to change how it is built. What we decide now will shape how hundreds of engineers work for years. You will learn a lot, and your work will have a real impact.\nThe team is small and growing: 3 engineers today, 6 next year. Its mission:\nOwn the backend building blocks every Alan product depends on, and make them simple enough that product teams use them without needing us.\nYour scope\nThe events pipeline. How our components and services talk to each other asynchronously: a Postgres outbox, Redis Streams, an S3 archive. It is in production for about 20 components. You make it a product that teams use on their own.\n\nData replication between services. A service publishes read-only tables. Other services keep a local, fresh copy and join on it. This replaces slow joins across components.\n\nTowards big services. The tools to take capabilities out of the monolith: a service template, APIs between services, traces across services, dependency management. We start with a pilot and turn it into a playbook.\n\nThe shared runtime. Queues, cache, the transaction layer. Their limits, their SLOs, their headroom.\n\nThe backend direction. The rules for how we build backends at Alan, written with the other engineering teams.\n\nThe stack\nPython, Flask, SQLAlchemy, PostgreSQL, Redis, RQ, Datadog, all in a monorepo. New services are async-first. We deploy daily and believe in distributed ownership: you build it, you own it. You don't need prior Python experience.\n⭐ Is it you we're looking for?\nExperience we value\n5+ years of backend engineering, with code other teams depend on: libraries, frameworks, pipelines, internal platforms. You ran it in production and owned it.\n\nDistributed systems as a daily tool: events and messaging (delivery guarantees, ordering, idempotence, retries), data replication, consistency, transactions.\n\nPostgreSQL in depth: transactions, locks, replication, query plans.\n\nYou have split a monolith or built services, step by step, while production kept running.\n\nYou measure before you optimise, and you set SLOs and alerts for what you own.\n\nEnglish working proficiency. French is not required.\n\nMindset we value\nProduct mindset. Product teams are your customers. Adoption is how you measure success.\n\nEnabler. You build things others use on their own, instead of doing the work for them.\n\nYou write to think and align. Short framing docs and decision records are how this team works with the rest of engineering.\n\nInfluence without authority. You get other teams to change how they build, with no reporting line.\n\nIncremental. One pilot first, then the playbook. No big-bang rewrites.\n\nStrong plus: you worked in a platform team that served product teams · event-driven architecture at scale · CDC or logical replication · async Python (asyncio, FastAPI) · multi-region or data residency · health, payments or other regulated data.\nNot required: frontend · Kubernetes and cluster operations · database administration · LLM or AI expertise. Other teams own those.\nMission alignment\nHealthcare technology excites you.\n\nLeveraging AI to redefine our roles and unlock scalability.\n\nFor this opportunity, we are aiming to hire at D level or above. These are senior individual-contributor seats. Your leverage comes from technical depth and from how many teams use what you build.\nBut above all, we are looking for high potential and curiosity: make sure to show us this when you apply! Everything else is a bonus.\nHow we work\nLocation: You must be legally eligible to work in France, Belgium, or Spain.\n\nRemote work: We offer remote work flexibility, but we value in-person collaboration.\n\nImportant note: we hire people, not roles.\nIf you're excited about this opportunity but don't check every box, we'd love to hear from you. Everyone, no matter how underrepresented, should feel free to apply, as it can only bring learnings or success.\nIf you identify yourself as a woman: Did you know that research shows women often apply only when meeting 100% of requirements?\nRemember, this is just a guide, not a checklist.\nWe'll be thrilled to receive your application!\n Check out our About Alan and Career pages, as well as our Medium, blog and Glassdoor page for more info.\nYou want to know more about Alan?\nPerks & Benefits: Alaners are provided with a stimulating environment and perks ensuring they are happy, efficient and spend only high-quality time with co-workers.\n\nA strong culture : People joining Alan are often surprised and delighted by our innovative working method. We have a set of cultural values that guide our approach to work.","description_format":"text","description_chars":6561,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"All levels","optional":false}]},"benefits":[],"hiring_locations":[{"name":"France","iso":"FR","kind":"country"},{"name":"Belgium","iso":"BE","kind":"country"},{"name":"Spain","iso":"ES","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Health Insurance & Benefits","InsurTech"],"lifecycle":[{"event":"open","at":"2026-10-29T19:45:18Z"}],"visa":[],"liveness":{"score":63,"band":"ok","label":"Likely open","p_open":1,"p_active":0.632,"p_room":1,"age_days":2,"expected_fill_days":16,"reasons":["conf:2","stale_co","velocity","win:early"],"computed_at":"2026-11-01T06:10:25Z"},"pay":null,"html_url":"https://alion.io/job/alan-senior-platform-engineer-xfm-backend-platform","json_url":"https://alion.io/job/alan-senior-platform-engineer-xfm-backend-platform.json","meta":{"generated_at":"2026-11-01T22:47:48Z","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":34656,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-02T00:00:00Z"}},"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":4773},"rest":"https://alion.io/mcp/rest/get_company?id=4773"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Falan-senior-platform-engineer-xfm-backend-platform"},{"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%2Falan-senior-platform-engineer-xfm-backend-platform"},{"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%2Falan-senior-platform-engineer-xfm-backend-platform"},{"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/alan-senior-platform-engineer-xfm-backend-platform\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Falan-senior-platform-engineer-xfm-backend-platform"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3479392}},{"tool":"search_jobs","arguments":{"company":"alan.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3479392},"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.
