<p><strong>ABOUT NEXGEN CLOUD</strong></p> <p>NexGen Cloud is a fast-growing GPU cloud and AI infrastructure business. We’re the company behind Hyperstack — a self-serve, on-demand cloud platform built for high-performance AI, HPC, and compute-heavy workloads. Powered by 100% renewable energy and NVIDIA architecture, Hyperstack gives teams from AI startups to enterprise the compute they need, without the cost or complexity of legacy cloud.</p> <p>We move fast, solve hard problems, and build things that matter. If you want ownership, real impact, and a front-row seat to one of the most consequential infrastructure shifts of the decade — this is the place.</p> <p><strong>THE ROLE: Technical Architect</strong></p> <p>We’re deploying large-scale NVIDIA GPU clusters, including GB200 and GB300 rack-scale systems, into live data centres on tight customer commit dates. On those schedules, a design error found on site costs weeks and real money. We need one architect per deployment who takes the high-level design and turns it into something that can actually be built, then stays with it until the customer signs off.</p> <p>This is a role for someone who would rather find the problem on paper than on the data hall floor. It suits someone who will push back on an inherited design or a customer requirement that won’t perform, and who carries authority through owning the design rather than managing people.</p> <p><strong>WHAT YOU’LL BE DOING</strong></p> <p>Rather than a checklist, here’s what success in this role actually looks like:</p> <ul> <li>Take each cluster from CTO handover to customer acceptance as its single design authority, so nothing is ordered or installed against a design you haven’t validated</li> <li>Turn high-level designs and initial BOMs into build-ready low-level designs, hall layouts, rack elevations, P2P maps and cable schedules that site teams can build from without having to call you</li> <li>Design the InfiniBand and Ethernet fabric, power, direct liquid cooling and containment to fit the real constraints of each data centre</li> <li>Validate every BOM before it goes to procurement, and make part substitution calls knowing exactly what breaks when a line changes</li> <li>Hold OEMs and integrators (NVIDIA, Dell, Lenovo, Supermicro and others) to their technical commitments, from FAT witness through to on-site issue resolution</li> <li>Build the reference designs and building blocks that mean each new deployment starts from a known-good baseline rather than a blank page</li> </ul> <p><strong>ABOUT YOU</strong></p> <p>We care more about how you think and work than a perfect CV. You’ll likely bring a combination of the following:</p> <p><em>Essential:</em></p> <ul> <li>You’ve designed and delivered large-scale GPU or HPC clusters into live data centres, and you were on site for the build</li> <li>Deep, practical knowledge of NVIDIA platforms (GB200/GB300 rack-scale and HGX H200/B200) and what each one demands of a facility</li> <li>Cluster-scale InfiniBand and Ethernet fabric design: topology, rail optimisation, oversubscription, and cable and optic selection</li> <li>Physical infrastructure design across power and redundancy, direct liquid cooling and CDUs, containment and achievable cable lengths</li> <li>You know part numbers, what’s optional and what isn’t, and you can hold an OEM to account when their commitments slip</li> </ul> <p><em>Nice to Have:</em></p> <ul> <li>Factory integration and FAT experience, including holding a dispatch gate</li> <li>Storage design for AI workloads (WEKA, VAST, DDN, Ceph or similar)</li> <li>Deployments across multiple geographies and data centre operators, including sites requiring fit-out</li> <li>Neocloud or hyperscale experience on compressed schedules</li> </ul> <p><strong>WHAT WE OFFER</strong></p> <ul> <li>Competitive salary and annual discretionary bonus scheme</li> <li>Employee wellbeing benefits</li> <li>25 days holiday, plus public holidays</li> <li>Private Medical Insurance</li> <li>Enhanced Pension Scheme</li> <li>Flexible working arrangements (remote or hybrid, depending on role and location)</li> <li>Real ownership and autonomy — the trust to take initiative and experiment</li> <li>Visible, meaningful impact as we scale</li> <li>Clear career progression in a high-growth company</li> <li>A collaborative, international culture built on trust, transparency, and ownership</li> <li>The chance to help shape NexGen Cloud’s team, culture, and future</li> </ul> <p><strong>WHY APPLY</strong></p> <p>We welcome applications from all backgrounds. If you enjoy solving complex infrastructure problems and want to build something meaningful at scale, we’d like to hear from you.</p> <p><strong>MORE INFORMATION</strong></p> <p>Visit our <a href="https://www.nexgencloud.com/careers">careers page</a> to learn more about us or follow us on <a href="https://www.linkedin.com/company/nexgen-cloud">LinkedIn</a> and <a href="https://x.com/CloudNexgen">X</a> to learn more about our journey and keep up with our latest news and releases.</p>
