Description du poste

🐼 Who we are

You. Better. With Alan.

Alan's vision is to make prevention the new norm of care for all. Our mission is to help people live in good health to 100 while helping employers feel proud, turning health benefits from a cost center into their most valuable investment.

We're building a vertically integrated health partner that seamlessly unites insurance and smart healthcare delivery into one system.

By connecting all aspects of care - private, public, and direct to consumer - we create the most member-centric healthcare experience. Through deep engagement, we empower everyone to overcome day-to-day health obstacles and live healthier lives.

We partner with 35K+ companies of all sizes, serving more than 950+ members, and have reached 680M+ in ARR.

Our team of 700 people (still growing) operates across France🇫🇷, Spain🇪🇸, Belgium🇧🇪, and Canada🇨🇦.

🤖 Mo Team ♥️

The Mo team is on a mission to redefine the future of care by building Mo, your health companion. Mo is 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 the Mo team is building 🤖.

We kicked off the project in 2023. After a strong R&D phase, we’re now testing real products with real users, and about to scale fast.

🚀 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. If you’re curious, here is a paper we published recently.

🎯 Is it you we’re looking for?

We’re looking for Product engineers with 3+ years of experience who get excited about building state-of-the-art AI systems and applying them to real-world, high-stakes problems in healthcare.

• You’ll work at the frontier of LLMs, multi-agent architectures, and human-in-the-loop learning — and see your work deployed in production, helping real people.
• You’ll implement new capabilities for Mo, working across engineering, data, and medical expertise
• You’ll work on making our systems and product scale, going from thousands to millions of active members in a short timeframe.
• You’ll have significant influence on system architecture and code quality
• You’ll mentor engineers, contribute to our product & engineering culture, and help build the team (including participating in hiring, shaping our interview loops, etc.).

You would be a good fit at Alan if most of this sounds like you:

• Strong background in software engineering, systems architecture, with a spike in back-end engineering.
• Experience with traditional ML, or LLMs, or ML dev ops is a big plus
• Product-minded: you want your solutions to be used, and impactful
• Self-directed and pragmatic
• Humble and still willing to grow (no matter your seniority!)
• Collaborative, enthusiastic about teamwork, learning, and teaching
• Fluent in English (no need to speak French!)

But above all, we are looking for high potential and curiosity: make sure to show us this when you apply! Everything else is a bonus.

For this opportunity, we are aiming to hire within the D-F level range.
