<p class="font-claude-response-body break-words whitespace-normal leading-[1.7]"><strong>Senior Infrastructure Engineer (OpenStack)</strong></p> <p class="font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]">Location: UK (Remote)</p> <p class="font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]">Department: Infrastructure</p> <p class="font-claude-response-body break-words whitespace-pre-wrap leading-[1.7]">Reporting to: Head of Infrastructure</p> <h4 class="text-text-100 mt-2 -mb-1 text-base font-bold">ABOUT NEXGEN CLOUD:</h4> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">NexGen Cloud is the company behind Hyperstack, a full-stack AI cloud serving tens of thousands of customers from AI researchers to enterprises running the world's most compute-intensive workloads. We deliver on-demand and private GPU infrastructure to teams who treat performance as a requirement, not a feature.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">We're a tight-knit, fast-moving team working at the cutting edge of AI cloud infrastructure. We practice what we preach, equipping our people with AI at every level so we can solve harder problems, ship faster, and keep raising the bar for what enterprise GPU infrastructure looks like.</p> <h4 class="text-text-100 mt-2 -mb-1 text-base font-bold">THE ROLE: Senior Infrastructure Engineer (OpenStack)</h4> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">This role exists because our platform is scaling quickly — and complexity comes with it. As we expand our OpenStack and Kubernetes environments globally, we need engineers who can take real ownership of how the platform is designed, operated, and improved. You'll have direct ownership over business-critical infrastructure that impacts performance, reliability, and customer experience.</p> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">This is not a maintenance role. If you like solving hard problems, owning systems end-to-end, and seeing the impact of your work immediately — you'll enjoy this.</p> <h4 class="text-text-100 mt-2 -mb-1 text-base font-bold">WHAT YOU'LL BE DOING:</h4> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">Rather than a long checklist, here's what success in this role looks like:</p> <ul class="[li_&amp;]:mb-0 [li_&amp;]:mt-1 [li_&amp;]:gap-1 [&amp;:not(:last-child)_ul]:pb-1 [&amp;:not(:last-child)_ol]:pb-1 list-disc flex flex-col gap-1 pl-8 mb-3"> <li class="whitespace-normal break-words pl-2">Own the design, deployment, and operation of OpenStack and Kubernetes environments — ensuring platform performance, scalability, and resilience for GPU workloads</li> <li class="whitespace-normal break-words pl-2">Build and improve infrastructure using infrastructure-as-code and GitOps practices, driving automation across provisioning, deployment, and operational workflows</li> <li class="whitespace-normal break-words pl-2">Optimise GPU workload scheduling using Kubernetes and NVIDIA tooling, and implement monitoring, logging, and alerting to ensure platform stability</li> <li class="whitespace-normal break-words pl-2">Lead incident response and drive continuous improvement of reliability across the platform</li> <li class="whitespace-normal break-words pl-2">Maintain strong security controls across infrastructure and container layers — RBAC, network policies, and tenant isolation</li> <li class="whitespace-normal break-words pl-2">Work closely with Platform, DevOps, AI, Product, and Support teams to align infrastructure capabilities with customer and platform requirements</li> </ul> <h4 class="text-text-100 mt-2 -mb-1 text-base font-bold">ABOUT YOU:</h4> <p class="font-claude-response-body break-words whitespace-normal leading-[1.7]">We're more interested in <strong>how you think and work</strong> than in a perfect CV.
