Description du poste

You. Better. With Alan. Alan is building a vertically integrated health partner that unites insurance and smart healthcare delivery into one seamless system. Our vision is to make prevention the new norm of care for all.

You. Better. With Alan. Alan is building a vertically integrated health partner that unites insurance and smart healthcare delivery into one seamless system. Our vision is to make prevention the new norm of care for all.

Our mission: Help people live in good health to 100 while helping employers feel proud, turning health benefits from a cost centre into their most valuable investment.

By connecting all aspects of care (private, public, and direct to consumer) we create the most member‑centric healthcare experience, reducing claims costs while generating new monetization opportunities.

We partner with tens of thousands of companies across France, Spain, Belgium, and Canada, serving over a million members.

How we work: our Leadership Principles

• Mission is the Boss — We think long‑term and are methodical optimists who take risks, seeking our mission's success above all else.
• Distributed Ownership — Accountable enlightened despots: everyone owns their decisions and results.
• Radical Transparency — All information is accessible and written‑first, so everyone can make the best decisions asynchronously.
• Always Growing — Direct, positive, and caring feedback, combined with self‑growth ownership.

Build the AI‑native company, for real.

Alan has spent 10 years developing a distinctive way of working: radical transparency, written culture, distributed decision‑making, no managers, no meetings by default. This wasn’t just philosophy. It was a deliberate architectural choice, and it made Alan one of the most productive companies in European tech.

Now, agentic AI empowers us to make it much more personalized. The principles that made Alan productive become the foundation for a much more ambitious journey: a company where AI agents handle organizational complexity, surface the right context instantly, and let every person focus on the work that matters.

As a Software Engineer on this team, you will:

• Build the AI‑powered internal platform that every Alaner uses daily to navigate the company, find context, and take action.
• Design and ship intelligent agents that automate real organizational workflows: onboarding, knowledge retrieval, performance alignment, decision support.
• Push LLMs into production for structured reasoning, agentic task execution, and deep integration with internal tools.
• Define the primitives and abstractions of AI‑native work, the patterns that scale across every team and every country Alan operates in.
• Replace generic tools (HRIS, performance reviews, IAM) with opinionated, Alan‑native software that compounds with our culture.
• Build and scale our Identity & Access Management (IAM), Privileged Access Management (PAM), and user lifecycle across 25+ systems.
• Collaborate with product, design, security and leadership to turn Alan's cultural principles into software that amplifies them.

Why this role is special

• Alan's written, transparent, async culture generates an extraordinary volume of structured organizational knowledge. Most companies can’t feed AI agents with high‑quality internal data. Alan already can.
• The team is building a full AI‑native operational layer from scratch, not adding copilots to legacy tools.
• Every Alaner uses what you ship, every day. The feedback loop between building and impact is immediate.
• The work sits at the frontier of applied AI: agents, retrieval‑augmented generation, structured outputs, tool use, human‑in‑the‑loop design.
• The ambition goes beyond Alan. The patterns you build here could define how high‑performance companies operate in the AI era.

Your playground

• Stack: Python/Flask, React, PostgreSQL, plus deep integration with LLM APIs and internal AI infrastructure.
• What you'll do: design and ship AI‑native tools that power how Alan works. automated workflows, organizational navigation, agentic assistants.
• Impact: your work shapes the daily experience of every Alaner and builds the playbook for the AI‑native company.

Who we're looking for

• Software engineers of all experience levels, ideally with backend or full‑stack experience.
• Genuinely excited about AI and eager to explore what LLMs, agents, and retrieval systems can do inside a real product.
• Comfortable building in fast‑moving territory where the right abstractions don't exist yet.
• Well‑versed in OOP languages (Python, Java, C#) and modern web technologies.
• Fluent in English (French is a plus but not required).
• Curious, self‑starting, humble, collaborative, and eager to grow.

Perks & benefits

• Fair rewards & equity packages.
• Flexible office & remote options.
• Top‑tier equipment: MacBook Pro, monitor, noise‑canceling headphones.
• Flexible vacation & hours.
• Comprehensive healthcare for you, children, and partners.
• Transport support and coaching for personal growth.
• Training budget for conferences, courses, books.
• Extended parental leave for all parents.

Recruitment note

We hire people, not roles. Don't worry if you don't check every box. High potential and curiosity matter most. We may even suggest another team if we see a better fit.
