Fullstack Software Engineer (x/f/m) - Backend Platform

Not for symptoms to get worse. 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.

Alan exists to end the wait.

Health 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.

So we are building the new standard in prevention insurance. Alan is the first company that integrates insurance, prevention, and care into a single, acclaimed user experience.

We are on an incredible journey to build a global leading company, with a unique culture. We already partner with 40K+ companies of all sizes, serving more than 1M+ members, and have reached €800M+ in ARR.

Prevention 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.

Every 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.

You 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.

This 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.

The team is small and growing: 3 engineers today, 6 next year. Its mission:

Own the backend building blocks every Alan product depends on, and make them simple enough that product teams use them without needing us.

• 5+ years of backend engineering, with code other teams depend on: libraries, frameworks, pipelines, internal platforms. You ran it in production and owned it.

• Distributed systems as a daily tool: events and messaging (delivery guarantees, ordering, idempotence, retries), data replication, consistency, transactions.

• PostgreSQL in depth: transactions, locks, replication, query plans.

• You have split a monolith or built services, step by step, while production kept running.

• You measure before you optimise, and you set SLOs and alerts for what you own.

• English working proficiency. French is not required.

• • You think in terms of platform as a product: other engineers are your customers

  • You simplify complexity with clear abstractions and long-term ownership

  • You are collaborative, humble, and motivated by enabling others

  • You leverage AI to redefine our roles and unlock scalability

  • Healthcare technology excites you

  • You are fluent in English (no French required)

• 3+ years in backend, platform, or infrastructure-oriented engineering roles

• Experience designing and maintaining internal services, APIs, or SDKs

• You love turning complex problems into elegant solutions

• You care about the "why" behind what you build, not just the "how"

We'll be thrilled to receive your application!
