Description du poste

Alan is a prevention‑focused insurance company looking to build a global leading company with a unique culture. The Engineering team creates the infrastructure, interfaces, and applications that deliver first‑class service to members, health professionals and internal teams.

Mission

• Tech Foundations enables product crews and creates an environment to thrive—combining world‑class infrastructure, intuitive developer experience, 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

• Hopper – Alan's own background coding agent: agent orchestration, parallel agent pools, web dashboard for builders
• AI‑native engineering enablement – harness integration, agentic workflows, and infrastructure for AI tools
• Autonomous testing infrastructure – agents that validate their own work before shipping
• Sandboxed development environments – remove 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 will move from “AI tools you monitor” to “AI agents you trust.” We will scale Hopper and the supporting infrastructure so that engineers routinely offload tasks to agents, and non‑engineers can open pull requests after easily testing their changes. Agents will validate their own work before it ships.

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
• Passion for creating delightful experiences, whether building UIs or APIs

Mindset we value

• Think in terms of platform experience: engineers are your primary customers, and you care about making AI‑native workflows reliable for everyone
• Collaborative, humble and motivated by enabling others
• Simplify complexity with elegant abstractions and maintainable code
• Excited about AI changing who gets to build – and want to be the one building that infrastructure
• Fluent in English (no French required)
• High potential and curiosity – we want to see this when you apply! Other qualifications are a bonus.

How we work

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

We hire people, not roles. If you’re excited about this opportunity but don’t meet every box, we’d love to hear from you. Everyone, especially those from under‑represented backgrounds, should feel free to apply.

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

Benefits

• Culture: Innovative working methods guided by a set of cultural values
• Perks: Stimulating environment and benefits that help you be happy, efficient and spend high‑quality time with co‑workers
