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

Overview

We build prevention insurance by integrating insurance, prevention and care into a single user experience. We are looking for an engineer to join our engineering team and help build the infrastructure, interfaces and applications that deliver first‑class service to members, health professionals and internal stakeholders.

Scope

• Hopper – build background coding agent orchestration, parallel agent pools and a web dashboard for builders.
• AI‑native engineering enablement – harness integration, agentic workflows and related tooling.
• Autonomous testing infrastructure – agents that validate their own work before shipping.
• Sandboxed development environments – removing brittle local setups to enable safe contribution.
• CI/CD and quality guardrails – auto‑fix, complexity scoring, automated checks and improved PR review experiences.
• Non‑engineer contribution tooling – flows and interfaces that empower Designers, PMs and Ops to contribute autonomously.

Qualifications

• 3+ years of full‑stack software engineering experience.
• 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.
• Proficiency in Python and front‑end frameworks such as React.
• Strong sense of developer experience and ability to design intuitive APIs and UIs.
• Fluency in English.
• Legal eligibility to work in France, Belgium or Spain.

Desired Mindset

• Think of platform experience with engineers as primary customers.
• Collaborative, humble and motivated by enabling others.
• Simplify complexity with elegant abstractions and maintainable code.
• Excited about AI changing who gets to build.
• High potential and curiosity.
