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.\n⭐ The Engineering team ⭐\nIn our engineering team, we build the infrastructure, interfaces, and applications to provide first-class service to our members, health professionals, and even ourselves!\nBeing an engineer at Alan means joining a team of talented, committed and passionate engineers, with a lot of product interaction.\nWe move fast, with a lot of ownership, and are proud to tackle big problems!\nOur process is very simple: those who make product decisions are the same ones who build them.\nWant to know more? Read this article if you want to discover how life as an Engineer at Alan and this article on our Engineering career pat\nThe stack\nPython services on FastAPI, async SQLAlchemy and PydanticAI, Temporal for durable execution, PostgreSQL, MCP, Daytona sandboxes, various LLM model providers, Terraform on AWS, React with Vite. Our main backend is a Flask monolith. We deploy daily and believe in distributed ownership: you build it, you own it.\nThe Agentic Platform area\nIn 2027, we expect to run more AI agents than we have employees.\nAgents already do real work at Alan. They answer members' health questions, resolve support requests, read medical documents, detect fraud, automate operational tasks, and write a large share of our code.\nBut every team building an agent ends up solving the same hard problems again: how to call models safely with health data, how to give an agent tools and the right permissions, how to know whether a prompt change made it better or worse, how to debug what it did. The result: several agent frameworks and evaluation stacks, each with its own security and compliance story.\nThe Agentic Platform area was created to fix that. Our mission: make it cheap, fast and safe for every Alaner or crew to build, run and improve agentic products and workflows.\nWe own the environment agents run in (infrastructure, runtime, evaluation, observability, skills lifecycle), with security, privacy and compliance by design, and the generalist products on top: Hopper and the Agent Studio. Product teams and all Alaners own their agents, skills, and their outcomes. We give them the paved road.\nTwo crews, one team:\nHopper is every Alaner's AI companion. Five months after it started, 80% of Alaners use it, 3k sessions are created each day, and about 30% of our pull requests are opened from it (watch how we built it).\n\nAI Product Platform builds the shared blocks every AI product at Alan runs on. For instance, our ops teams now build agents autonomously on our Ops AI Platform (read how, watch the talk).\n\nProblems you'll only find here\nRun agents at scale\nOne runtime for every AI product. A shared agent framework, from a single model call to multi-agent workflows with live streaming, and one gateway to every model: routing, failover across providers, quotas and cost per use case built in.\n\nAgent sessions that last for hours. Durable sessions, started from the web, Slack, Linear or GitHub, that survive pod restarts and deploys, and pick up exactly where they left off.\n\nSandboxes at scale. An isolated environment for every agent session and every evaluation, on an infrastructure compliant with sensitive data, with negligible boot overhead.\n\nMake agents trustworthy and proactive\nOne tool gateway to the whole company. An MCP gateway that connects agents to internal tools and data, external services, computer use, managing identity and credentials.\n\nAgents safely acting on critical data. We give each agent no more than the access it needs. Every tool call goes through identity, permissions, confirmations and audit. No sensitive data leaks.\n\nEvals you can replay in time. Re-run an agent or skill against production as it was at a past point in time, on real data, safely isolated. Anyone can ship knowing their change is an improvement rather than a regression.\n\nAgents and skills that proactively fix themselves. Every run is traced, and every human correction, failed tool call or escalation becomes a prioritized fix that Hopper can apply.\n\nPut agents in everyone's hands\nSkills as a product. A registry where Alaners and teams publish, share and version their skills, so that nothing needs to be repeated twice.\n\nAI that non-engineers can own. Alaners who ship code through Hopper, Operators or Sales who build their own agents or skills in our Studio and operate them from their day-to-day tools.\n\nAutomations and artifacts. Agents that run on a schedule or on an event, and build the dashboards and hosted sites that become the go-to places for collaboration.\n\n⭐ Is it you we’re looking for?\nWhat you'll do\nOwn some of the problems above end to end, from design to production, with significant influence on architecture and code quality\n\nWork closely with the people who use what you build: Alaners, product teams, ops\n\nOwn reliability, cost and security in production\n\nMentor engineers, contribute to our product and engineering culture, and help build the team\n\nExperience we value\n3+ years in software engineering, with solid backend fundamentals\n\nPlatform-leaning or product-leaning: both are welcome. Depth in at least one of: distributed systems and runtimes, evaluation and data quality, security and authorization, product UX\n\nA good sense of user and developer experience, whatever you build\n\nYou built products, platforms or infrastructure used by other people\n\nExperience with LLM APIs, agent frameworks, evals or MCP is a strong plus; ML or MLOps experience is a plus\n\nMindset we value\nYou measure success by adoption, not by what is available\n\nYou make concrete tradeoffs between speed, reliability, cost, security and user experience\n\nYou simplify complexity with clear abstractions and maintainable code\n\nYou care about whether people can understand and verify what an AI system did\n\nYou keep up with the latest AI technology and know the open-source AI ecosystem\n\nSelf-directed, pragmatic, humble, collaborative, enthusiastic about learning and teaching\n\nExcited about AI changing who can build, investigate and automate work\n\nAbove all, we look for high potential and curiosity: make sure to show us this when you apply. Everything else is a bonus.\nYou should be fluent in English (no French required).\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\nPerks & Benefits\nAt Alan, we believe that being in good health is a basic need, and it starts with our employees.
