About Mistral

At Mistral, we are on a mission to democratize AI, producing frontier intelligence for everyone. We develop models for the enterprise and for consumers, focusing on delivering systems which can really change the way in which businesses operate and which can integrate into our daily lives.

What will you do?

  • Research and develop novel methods to push the frontier of large language models
  • Work across use cases (e.g reasoning, code, agents) and modalities (e.g text, image and speech)
  • Build tooling and infrastructure to allow training, evaluation and analysis of AI models at scale
  • Work cross-functionally with other scientists, engineers and product teams to ship AI systems which have a real-world impact

About you

  • You are a highly proficient software engineer in at least one programming language (Python or other, e.g. Rust, Go, Java)
  • You have hands-on experience with AI frameworks (e.g. PyTorch, JAX) or distributed systems (e.g. Ray, Kubernetes)
  • You have high engineering competence. This means being able to design complex software and make it usable in production

Now, it would be ideal if
