Linux Engineer - Linux SME at Hedge Fund

Join a high‑performance platform engineering team at a fast‑moving, tech‑driven fund where you’ll own the Linux estate that powers low‑latency trading and cutting‑edge LLM workloads.

You’ll design and run global infrastructure across data centres and co‑lo sites, tuning Linux kernels for raw speed and rock‑solid stability while pushing efficiency through Infrastructure as Code with Ansible, Python and Terraform.

You’ll be hands‑on with RHEL in production, GPU‑enabled Linux servers, storage and networking, building and automating everything from standardised builds to CI/CD pipelines and observability for mission‑critical systems. Expect to lead continuous improvement, ripping out toil and automating wherever you can to boost scalability, resilience and developer velocity.

This is a 250‑person, fintech‑style environment: limited red tape, direct impact, and engineers truly empowered to make decisions and ship change quickly.

It’s a role for engineers who think in milliseconds, care about kernel flags and NUMA layouts, and love building platforms that scale.
