Job description

Engineering team

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 1000+ people. If it speaks to you: we're hiring across France, Spain, Belgium, and Canada. And beyond.

Tasks

Run agents at scale. One runtime for every AI product. A shared agent framework, from a single model call to multi-agent workflows with live streaming, and one gateway to every model: routing, failover across providers, quotas and cost per use case built in.

Agent sessions that last for hours. Durable sessions, started from the web, Slack, Linear or GitHub, that survive pod restarts and deploys, and pick up exactly where they left off.

Sandboxes at scale. An isolated environment for every agent session and every evaluation, on an infrastructure compliant with sensitive data, with negligible boot overhead.

Make agents trustworthy and proactive. One tool gateway to the whole company. An MCP gateway that connects agents to internal tools and data, external services, computer use, managing identity and credentials.

Agents safely acting on critical data. We give each agent no more than the access it needs. Every tool call goes through identity, permissions, confirmations and audit. No sensitive data leaks.

Evals you can replay in time. Re-run an agent or skill against production as it was at a past point in time, on real data, safely isolated. Anyone can ship knowing their change is an improvement rather than a regression.

Agents and skills that proactively fix themselves. Every run is traced, and every human correction, failed tool call or escalation becomes a prioritized fix that Hopper can apply.

Put agents in everyone's hands. Skills as a product. A registry where Alaners and teams publish, share and version their skills, so that nothing needs to be repeated twice.

AI that non-engineers can own. Alaners who ship code through Hopper, Operators or Sales who build their own agents or skills in our Studio and operate them from their day-to-day tools.

Automations and artifacts. Agents that run on a schedule or on an event, and build the dashboards and hosted sites that become the go-to places for collaboration.

Is it you we’re looking for? Own some of the problems above end to end, from design to production, with significant influence on architecture and code quality. Work closely with the people who use what you build: Alaners, product teams, ops. Own reliability, cost and security in production. Mentor engineers, contribute to our product and engineering culture, and help build the team.

Requirements

• 3+ years in software engineering, with solid backend fundamentals
• Platform-leaning or product-leaning: both are welcome
• Depth in at least one of: distributed systems and runtimes, evaluation and data quality, security and authorization, product UX
• A good sense of user and developer experience, whatever you build
• You built products, platforms or infrastructure used by other people
• Experience with LLM APIs, agent frameworks, evals or MCP is a strong plus; ML or MLOps experience is a plus
• You measure success by adoption, not by what is available
• You make concrete tradeoffs between speed, reliability, cost, security and user experience
• You simplify complexity with clear abstractions and maintainable code
• You care about whether people can understand and verify what an AI system did
• You keep up with the latest AI technology and know the open-source AI ecosystem
• Self-directed, pragmatic, humble, collaborative, enthusiastic about learning and teaching
• Excited about AI changing who can build, investigate and automate work
• Above all, we look for high potential and curiosity: make sure to show us this when you apply. Everything else is a bonus.
• You should be fluent in English (no French required).
