## Description

We're seeking a HPC Network Engineer to join our founding team who will design and run the high-performance network that connects our GPU compute - building a fast, reliable fabric today and the architecture to scale it as our cluster grows.

 * Design, optimize, and scale the high-performance network fabric that interconnects our GPU and CPU compute.
 * Build the low-latency networking that keeps our training and simulation workloads fed and fast.
 * Own capacity planning and lead network projects end to end, from design through deployment.
 * Partner with vendors to select and engineer switches that set us up for the next stage of compute growth.
 * Develop scripts and processes that automate network operations and increase efficiency.
 * Collaborate across the infrastructure team to solve cross-discipline problems with immediate operational impact.
