Description
About Mistral AI ------------------- Mistral AI is an AI technology company that develops high-performance, optimized, open-source and cutting-edge models, products and solutions.
Role Summary – Software Engineering track --------------------------------------- As a Research Engineer on the software side, you will design and harden the codebase, tools and distributed services that let our scientists train and ship frontier-scale models. You do not need prior ML experience; what matters is writing clean, reliable code that scales. You will join our Platform REs team to build and maintain shared dev-tools, evaluation & data pipelines, training framework, cluster tooling and CI/CD.
Responsibilities ---------------
- Accelerate researchers by owning the complex parts of large-scale pipelines and delivering robust internal tooling.
- Interface research with product: expose clean APIs, automate model pushes, surface live metrics.
- Write efficient, well-tested Python and systems code; enforce code review, CI, and observability.
- Design and optimise distributed services (Kubernetes / SLURM, thousands-of-GPU jobs).
- Prototype utilities (CLI, dashboards) and carry them through to stable, shared libraries.
About the Research Engineering team --------------------------------- Based in Paris and London, our REs move fluidly along the research ↔ production spectrum. Engineers can rotate between Platform and Embedded tracks as their interests evolve.
About you ----------
- Master’s in Computer Science (or equivalent experience).
- 4 + years building and operating large-scale or distributed systems.
- Strong software-design instincts: modular code, tests, CI/CD, observability.
- Fluency in Python plus one systems language (C++, Rust, Go or Java).
- Hands-on with container orchestration and schedulers (Kubernetes / K8s, SLURM, or similar).
- Comfortable profiling performance, optimising I/O, and automating workflows.
- Self-starter, low-ego, collaborative, high-energy.
