Full-stack Software Engineer (x/f/m) - AI Developer Tools

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

• 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.

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.

Everyone Can Build crew — within Tech Foundations area

Mission: 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

• Hopper — Alan's own background coding agent: agent orchestration, parallel agent pools, web dashboard for builders
• AI-native engineering enablement — Harness integration, agentic workflows, ...
• Autonomous testing infrastructure — agents that validate their own work before shipping
• Sandboxed development environments — removing brittle local setups so everyone can contribute safely
• CI/CD and quality guardrails — auto-fix, complexity scoring, automated checks and new PR review experiences that enable confident reviewing
• 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?

• 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.

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.

Important note: we hire people, not roles.

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

Perks & Benefits

Alaners are provided with a stimulating environment and perks ensuring they are happy, efficient and spend only high-quality time with co-workers. A strong culture: People joining Alan are often surprised and delighted by our innovative working method. We have a set of cultural values that guide our approach to work.

A quick note about the process

Note: While you're applying for a specific area, you may join a different engineering team based on where we think you'll have the most impact.
