About The Position

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.

Requirements

• 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.

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.
