HPC/ GPU Cluster Architect

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, deploy new environments, 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 5+ years of experience with hands-on designing, architecting and scaling at least one HPC or GPU compute cluster in production (ideally >1,000 GPUs, but not required)

• You deeply understand server hardware fundamentals, including GPUs, NICs, PCIe, memory, thermals, and power

• You’re comfortable debugging performance and reliability issues across hardware, OS, drivers, and networking layers; full-stack.

• The idea of automating fleet operations (provisioning, monitoring, remediation) excites you — you embrace infrastructure-as-code

• You appreciate, value, and generate strong operational documentation and runbooks

• You have the ability and willingness to mentor junior engineers and contribute to team culture

• You’re open to domestic travel when required

• Familiarity with data center operations including power, cooling, and colo/vendor engagements

• Strong Linux systems administration experience, including kernel drivers, RDMA stack tuning, and performance analysis

• Experience with schedulers and orchestration systems such as Slurm and Kubernetes

• Exposure to virtualization technologies (KVM, QEMU, libvirt)

• Experience utilizing telemetry pipelines for predictive hardware failure detection

• Experience troubleshooting high-speed fabrics such as InfiniBand and/or RoCEv2 Ethernet
