Research Scientist - Mo Team

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.
