Principal/Staff HPC Network Engineer

San Francisco Compute (SFC) exists to give ambitious teams large scale supercomputers without taking on a catastrophic balance sheet risk. We are building the next generation of AI infrastructure, making large-scale GPU computing more accessible, flexible, and financially sustainable.

Unlike traditional GPU cloud providers, SFC combines supercomputer development and operations with an innovative compute marketplace, giving customers the flexibility to scale without the risks of rigid, long-term contracts.

We are a fast-growing team of ambitious, technically driven people working to shape the future of AI infrastructure. Our leadership team brings deep experience from Lambda, Crusoe, AWS, DigitalOcean, Hut 8, and Voltage Park, with a track record of deploying 8GW of data center capacity and hundreds of thousands of GPUs.

There has never been a more critical moment in history, and it is up to us to shape it on behalf of those who come after us. If you're excited by complex challenges, bold ideas, and meaningful impact, we'd love to meet you.

GPU clusters are some of the most performant computers on the planet. Even smaller clusters by today’s standards would have ranked in the TOP500 five years ago. Our infrastructure team is responsible for architecting and deploying new clusters around the world and keeping them running smoothly. You’ll participate in on-call rotation, fix issues when they arise, and lean into automation to enable deployments at scale. We’re a small but ambitious team so you’ll be an early contributor helping to shape culture, mentor junior engineers, and learn from our customers.

• You will have 10+ years of experience with hands-on management or architecture with network for at least one GPU cluster in the past (ideally a cluster with >1k GPU’s but not required)

• You deeply understand the fundamentals of Ethernet (RoCEv2) and/or InfiniBand networks in CLOS/fat-tree topologies

• You have built HPC network architectures (eBGP, fat-tree, VXLAN, MCLAG, etc.)

• The idea of implementing zero-touch provisioning for a large multi-layer network excites you (you embrace automation)
