AI Scientist

As an AI Scientist, you will push the boundaries of AI by developing and scaling cutting-edge models. This role exists to advance Mistral’s mission of democratizing frontier intelligence, enabling businesses and consumers to benefit from open, high-impact AI systems. You will collaborate with a global, cross-functional team to design, build, and deploy models that solve real-world problems across reasoning, code, and multimodal applications. Your work will directly shape how AI integrates into daily life and enterprise operations.

Responsibilities

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

Requirements

Highly proficient software engineer in at least one programming language (Python or other, e.g. Rust, Go, Java); hands-on experience with AI frameworks (e.g. PyTorch, JAX) or distributed systems (e.g. Ray, Kubernetes); high engineering competence - able to design complex software and make it usable in production; self-starter, autonomous and team player

Nice to have

Hands-on experience with training large transformer models in a distributed fashion; able to navigate the full MLOps stack, for instance, fine-tuning, evaluation and deployment; strong publication record in a relevant scientific domain

Benefits

healthcare coverage; parental leave; retirement plans; relocation support; wellness programs; meal and transportation allowances; location-specific perks
