About The Job

Mistral AI is seeking an Applied Scientist to drive innovative research and facilitate the adoption of its products among customers, collaborating with them to address complex technical challenges.

The Applied Scientist will be an integral part of our Applied AI Engineering team, which is dedicated to driving the successful deployment of Mistral AI products. They will work hand-in-hand with customers from the pre-sale stage to post-implementation, ensuring our solutions meet and exceed client expectations.

In this role, you’ll manage daily customer relations involving multiple stakeholders (CEO/CTO, data scientists, and software engineers) and function as a key resource in externalizing our research in production settings.

What you will do

  • Run pre-training, post-training and deploy state of the art models on clusters with thousands of GPUs. You don’t panic when you see OOM errors or when NCCL feels like not wanting to talk
  • Generate and curate data for pre-training and post-training, working on evaluations and making sure the model’s performance beats expectations
  • Develop the necessary tools and frameworks to facilitate data generation, model training, evaluation and deployment
  • Collaborate with cross-functional teams to tackle complex use cases using agents and RAG pipelines
  • Manage research projects and communications with client research teams


About You

  • You are fluent in English, and have excellent communication skills. You are at ease explaining complex technical concepts to both technical and non-technical audiences
  • You’re an expert with PyTorch or JAX
  • You’re not afraid of contributing to a big codebase and can find yourself around independently with little guidance
  • You write clean, readable, high-performance, fault-tolerant Python code
  • You don’t need roadmaps: you just do. You don’t need a manager: you just ship
  • Low-ego, collaborative and eager to learn
  • You have a track record of success through personal projects, professional projects or in academia


It would be great if :

  • You hold a PhD / master in a relevant field, however, whatever your background - if you’re an exceptional candidate, you should apply
  • Can bring a variety of research experience (agents, multi-modality, robotics, diffusion, time-series)
  • Have contributed to a large codebase used by many (open source or in the industry)
  • Have a track record of publications in top academic journals or conferences
  • Love improving existing code by fixing typing issues, adding tests and improving CI pipelines
