Role Summary 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 Research Software Engineering team to build and maintain shared dev-tools, evaluation 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 and 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.
Nice-to-haves Exposure to ML workloads or data-processing pipelines.
Experience with GPU clusters or CUDA.
Open-source contributions or widely used internal tools.
Location and Remote This role is primarily based at one of our European offices (Paris, Warsaw, Zurich and London).
We will prioritize candidates who either reside there or are open to relocating.
We strongly believe in the value of in-person collaboration to foster strong relationships and seamless communication within our team.
In certain specific situations, we will also consider remote candidates based in France
