Description du poste

Health can’t wait.

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 800+ people. If it speaks to you: we're hiring across France, Spain, Belgium, and Canada. And beyond.

The Engineering team

In our engineering team, we build the infrastructure, interfaces, and applications to provide first-class service to our members, health professionals, and even ourselves!

Being an engineer at Alan means joining a team of talented, committed and passionate engineers, with a lot of product interaction.

We move fast, with a lot of ownership, and are proud to tackle big problems!

Our process is very simple: those who make product decisions are the same ones who build them.

The Stack

Python/Flask, React, React Native, PostgreSQL in a monorepo. We deploy daily and believe in distributed ownership - you build it, you own it.

The Everyone Can Build crew — within Tech Foundations area

Mission:

• Tech Foundations enables product crews and creates the environment to thrive—combining world‑class infrastructure, intuitive developer experience, exquisite operational excellence, and built‑in security to make shipping exceptional products effortless.
• Everyone Can Build is one of its crews. Its mission: propel Alan into the AI‑native engineering era, by building the tools, agents, and infrastructure that let both engineers and non‑engineers contribute confidently and sustainably at scale.

Scope:

1. Hopper — Alan's own background coding agent: agent orchestration, parallel agent pools, web dashboard for builders
2. AI‑native engineering enablement — Harness integration, agentic workflows, …
3. Autonomous testing infrastructure — agents that validate their own work before shipping
4. Sandboxed development environments — removing brittle local setups so everyone can contribute safely
5. CI/CD and quality guardrails — auto‑fix, complexity scoring, automated checks and new PR review experiences that enable confident reviewing
6. Non‑engineer contribution tooling — flows and interfaces that make Designers, PMs and Ops autonomous contributors

Focus for 2026:

In 2026, we're moving from "AI tools you monitor" to "AI agents you trust." That means scaling Hopper — Alan's own background coding agent — alongside the infrastructure that makes it reliable: managed agent pools, sandboxed environments, autonomous testing, and CI auto‑fix. Engineers will routinely offload tasks to agents. Non‑engineers will open pull requests after having easily tested their changes. Agents will validate their own work before it ships.

Is it you we’re looking for?

Experience we value

• 3+ years in full‑stack software engineering roles
• Experience building internal platforms, frameworks, CLIs, or libraries that improve developer workflows
• Experience with LLM APIs, agent orchestration frameworks, or AI‑assisted coding tools is a strong plus
• You care about creating delightful experiences, whether building UIs or APIs

Mindset we value

• You think in terms of platform experience: engineers are your primary customers, and you care about making AI‑native workflows reliable for everyone
• You are collaborative, humble, and motivated by enabling others
• You simplify complexity with elegant abstractions and maintainable code
• You're excited about AI changing who gets to build — and want to be the one building that infrastructure
• You are fluent in English (no French required)
• But above all, we are looking for high potential and curiosity: make sure to show us this when you apply! Everything else is a bonus.

How we work

• Location: You must be legally eligible to work in France, Belgium, or Spain.
• Remote work: We offer remote work flexibility, but we value in‑person collaboration

We welcome all applicants, including those who don't meet every requirement. Everyone, no matter how underrepresented, should feel free to apply, as it can only bring learnings or success.

If you identify yourself as a woman: Did you know that research shows women often apply only when meeting 100% of requirements?

Remember, this is just a guide, not a checklist.

We'll be thrilled to receive your application!
