Summary:

Trading and research at the firm run around the clock and across the globe, and they run on infrastructure this team designs, builds, and operates.

As part of R&D, you will join the engineers responsible for the compute, storage, operating systems, and automation behind that work at serious scale: hundreds of petabytes of storage and large CPU and GPU clusters spanning thousands of nodes.

The role is broad by design. One week you might be shaping the architecture of a new AI cluster, the next profiling a training job that will not scale, the next writing automation that keeps the whole fleet healthy with minimal human intervention.

Responsibilities:

• Design, deploy, and scale distributed GPU clusters, from hardware selection and network topology through to production operation.
• Track down performance bottlenecks across the full stack: compute, storage, network, and the seams between them.
• Partner with researchers to profile and benchmark GPU workloads, then turn the findings into measurable speedups.
• Build the automation that lets a small team operate thousands of nodes: provisioning, monitoring, diagnostics, and self-healing.
• Own infrastructure projects end to end, from scope and design through implementation and long-term support.
