HPC/ GPU Cluster Architect

HPC/ GPU Cluster Architect LocationSan Francisco, CAEmployment TypeFull timeDepartmentEngineeringCompensation$220K – $300K • Offers EquityWe're building the company which will de-risk the largest infrastructure build-out in history.When people finance GPU clusters, the datacenters housing them, and the infrastructure powering them, they need "offtake" - meaning someone has signed a contract to lease the cluster for a period of time before its even built.Financing a GPU cluster is inherently risky, since margins are thin and volumes are huge. Lenders don't want to take on the risk that cluster developers can't repay their loan, and cluster developers really don't want to risk not selling their cluster. As a result, risk is offloaded to the customer using fixed-price long-term contracts.If you don't mitigate this customer risk, there's a bubble. This isn't SaaS anymore - application layer companies sign multi-year contracts for computer and inference, but sell to customers on monthly subscriptions. If you mess up a purchase, it's game over: a minor shift in your revenue growth rate might mean the difference between profit or bankruptcy. But what if companies could exit their contract by selling it back to the market?Otherwise, as AI scales, compute only becomes available to folks who can effectively take on that risk. A 2-person startup in a San Francisco Victorian can't realistically sign a 5-year take or pay contract on $100m supercomputers. But they may be able to buy the month of liquidity that someone else sold back.So that's what we make: a liquid market for GPU offtake.About the RoleGPU 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.About YouYou 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 powerYou’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-codeYou appreciate, value, and generate strong operational documentation and runbooksYou have the ability and willingness to mentor junior engineers and contribute to team cultureYou’re open to coming in to our San Francisco office 3–4 days per weekYou’re open to domestic travel when requiredSome Nice to HavesFamiliarity with data center operations including power, cooling, and colo/vendor engagementsStrong Linux systems administration experience, including kernel drivers, RDMA stack tuning, and performance analysisExperience with schedulers and orchestration systems such as Slurm and KubernetesExposure to virtualization technologies (KVM, QEMU, libvirt)Experience utilizing telemetry pipelines for predictive hardware failure detectionExperience troubleshooting high-speed fabrics such as InfiniBand and/or RoCEv2 EthernetBenefitsGenerous equity grantTeam members are offered a competitive salary along with equity in the companyVisa SponsorshipsYes, we sponsor visas and work permitsRetirement matchingWe match 401(k) plans up to 4%Medical, dental & visionWe offer competitive medical, dental, vision insurance for employees and dependents and cover 100% of premiumsTime offWe offer unlimited paid time off as well as 10+ observed...
