Cssmerge Staff HPC Network Engineer responsible for designing, optimizing, and scaling the high-performance network fabric connecting GPU and CPU compute. Leads network projects end to end and collaborates across infrastructure teams.
Responsibilities
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.
