Mobile Software Engineer (x/f/m) - AI Health Companion

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: our Leadership Principles 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. 🐼 Who we are We’re building Mo — a health companion for everyone. We’re a small team within Alan, on a mission to redefine the future of care by democratizing access to medical expertise . We are building Mo, an intelligent, empathetic, multimodal LLM-based conversational AI assistant able to prescribe, triage, and proactively follow up on care. Imagine giving every person in the world instant, 24/7 access to personalised medical expertise - through chat, voice, or video. That’s what we are building 🤖. We kicked off the project in 2023. After a strong R&D phase, we’re now scaling Mo to our entire French portfolio (1M members), and then our other countries. 🐼 Powered by Alan ♥️ You. Better. With Alan. We’re part of Alan, a leading European health insurance and healthcare company. That gives us access to world-class resources: 1M+ members , 32,000+ client companies , €780M+ ARR , a talented team of 700+ people , strong positioning in AI (co-founded Mistral AI) We benefit from Alan’s platform , infrastructure, distribution, and health expertise — but operate with the speed and focus of a startup. If you’re curious about Alan’s broader vision, our Shareholder Letters are worth a read. 🚀 What keeps us up at night We’re building a medical agent that works — reliably, safely, and at scale . You’ll work at the intersection of product engineering, ML engineering, and medical expertise . Our mission is to build the most accurate and reliable medical agent in the world , while delivering an outstanding conversational experience . Things we’re working on: 💬 Deliver the most memorable chatting experience — You’ll work on making Mo the obvious choice when it comes to asking a health question. It means having a world-class snappy and delightful chatting experience, blazing fast time to answer, and rich content shared. 🚀 Scaling our systems to serve 100x more users — You’ll work on preparing Mo for unprecedented scale, going up to a few millions of members to serve early in 2026. You’ll work on our latency, error rate, and error recovery, as any bug makes us lose members that would have used Mo on weekly basis otherwise. 🧱 Integrate Mo with all Alan services — You’ll work on integrating Mo with our other services (digital chat with HP, map of physical location of HPs, tailored prevention programs, …) to increase the value we deliver to our members. ➕ Extend our architecture to support the next chapters of Mo — You’ll work on our architecture, and agentic framework, to support Mo’s next needs (get more context, use new skills, be accessible in other countries we operate in) If you’re excited by the idea of building the future of healthcare, this is the team for you - we're at the start of the journey.
