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 testing real products with real users, and preparing to scale fast.

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: 700,000+ members, 32,000+ client companies, €500M+ ARR, a talented team of 600+ 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, their Shareholder Letters (2025-Q1, 2024-Q4) 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 AI Research And Clinical Application. 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
Build internal medical models — You’ll develop and evaluate foundation models and fine-tuned architectures for structured clinical reasoning. This includes working with curated datasets (e.g. clinical cases, EMRs, guidelines), building doctor-like reasoning agents, and iterating closely with medical experts.
Inject knowledge in clinical workflows — You’ll augment generation with structured clinical knowledge (e.g. drug databases, guidelines) using retrieval pipelines and hallucination-mitigation strategies.
Push the frontier of voice-based agents for healthcare — You’ll research and deploy streaming speech recognition and context-aware state switching — enabling Mo to handle real-time dialogue like a human clinician would.
Develop eval frameworks for clinical AI —You’ll design and run evals, by hand and programmatically, to understand where our agents fail and improve them.
Build lifelong memory and personalization infrastructure — You’ll explore architectures for dynamic memory and personalized reasoning, enabling Mo to be a personal, relevant health companion
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 Research Scientists with 3+ years of experience (or equivalent research track record) 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 tackle open-ended, high-risk research problems that demand rigor, creativity, and speed.
You’ll work at the intersection of AI research and healthcare products, collaborating daily with doctors, engineers, and designers.
You’ll have significant influence on research directions, system architecture, and evaluation methodology.
You’ll mentor engineers and scientists, contribute to our research 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 machine learning, deep learning, and/or large-scale model training
Experience with LLMs, RLHF, multi-agent systems, retrieval-augmented generation, or speech processing is a big plus
Product-minded: you want your research to be used, not just written about
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.
