h3bHealth can’t wait /b. /h3 /brpNot 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. /p /brpAlan exists to end the wait. /p /brpHealth 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. /p /brpSo 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. /p /brpWe 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. /p /brpPrevention 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. /p /brh3bThe Engineering team /b /h3 /brpIn our engineering team, we build the infrastructure, interfaces, and applications to provide first-class service to our members, health professionals, and even ourselves /p /brpBeing an engineer at Alan means joining a team of talented, committed and passionate engineers, with a lot of product interaction. /p /brpWe move fast, with a lot of ownership, and are proud to tackle big problems /p /brpOur process is very simple: those who make product decisions are the same ones who build them. /p /brh3bThe Stack /b /h3 /brpPython/Flask, React, React Native, PostgreSQL in a monorepo. We deploy daily and believe in distributed ownership
- you build it, you own it. /p /brh3bThe Hopper crew /b /h3 /brpbMission: /b /p /brul /brliHopper is Alan's internal agentic AI platform and every Alaner's AI companion: one unified productivity tool for coding, data, automation, research, and everyday work. /li /brliIt is a platform with a product on top. The product is the first and most demanding user of reusable components for agent orchestration, isolated execution, skills, connectors, permissions, audit, and evaluations. /li /br /ul /brpIt started as a coding agent. Watch how we built its first version and enabled anyone at Alan to ship code. Coding remains its most mature use case and the foundation we are expanding from. /p /brpbScope: /b /p /brol /brlibProduct experience /b
- durable AI sessions available from the web, Slack, Linear, and GitHub for coding, data analysis, automation, and general work /li /brlibAgent runtime and orchestration /b
- control plane, harness, model routing, long-running execution, recovery, and isolated sandboxes /li /brlibSecure connectors /b
- an MCP Gateway that manages identity, credentials, permissions, confirmations, sensitivity, and audit /li /brlibSkills, automations, and artifacts /b
- reusable workflows, scheduled or event-driven work, dashboards, and hosted tools /li /brlibTrust and review /b
- evaluations and product experiences that expose tests, screenshots, previews, queries, sources, and tool actions /li /br /ol /brpbFocus for 2026: /b /p /brpCoding proved that Alaners want to delegate meaningful work to agents. Our 2026 focus is to make it the AI companion every Alaner can rely on: faster and more durable sessions, safe access to company tools and data, HDS-compatible infrastructure for sensitive workloads, stronger evaluations, and results people can inspect before acting on them. /p /brpbFocus for 2026: /b /p /brpIn 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. /p /brh3bIs it you we’re looking for? /b /h3 /brh3bExperience we value /b /h3 /brul /brli3+ years in full-stack software engineering roles /li /brliExperience building products, internal platforms, frameworks, or infrastructure used by other people /li /brliDepth in at least one relevant area: AI agents and evaluations, developer platforms, high-quality product UX, distributed systems and runtimes or security and authorization /li /brliAbility to own work end to end, from a React interaction or API contract to reliability in production /li /brliExperience with LLM APIs, agent harnesses, MCP, or AI-assisted coding tools is a strong plus /li /br /ul /brh3bMindset we value /b /h3 /brul /brliYou think in terms of both product and platform
