Health can't wait . But that's exactly how healthcare works today. 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 integral leading company, with a unique culture.

If it speaks to you: we're hiring across France, Spain, Belgium, and Canada.

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. 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.

Own the backend building blocks every Alan product depends on, and make them simple enough that product teams use them without needing us. 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. Data replication between services. Other services keep a local, fresh copy and join on it. We start with a pilot and turn it into a playbook. The backend direction.

Python, Flask, SQLAlchemy, PostgreSQL, Redis, RQ, Datadog, all in a monorepo. We deploy daily and believe in distributed ownership: you build it, you own it. You don't need prior Python experience. Is it you we're looking for? 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. English working proficiency. French is not required. async Python (asyncio, Fast #
