Technical Architect

&lt;p&gt;&lt;strong&gt;ABOUT NEXGEN CLOUD&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;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.&lt;/p&gt; &lt;p&gt;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.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;THE ROLE: Technical Architect&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;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.&lt;/p&gt; &lt;p&gt;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.&lt;/p&gt; &lt;p&gt;&lt;strong&gt;WHAT YOU’LL BE DOING&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;Rather than a checklist, here’s what success in this role actually looks like:&lt;/p&gt; &lt;ul&gt; &lt;li&gt;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&lt;/li&gt; &lt;li&gt;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&lt;/li&gt; &lt;li&gt;Design the InfiniBand and Ethernet fabric, power, direct liquid cooling and containment to fit the real constraints of each data centre&lt;/li&gt; &lt;li&gt;Validate every BOM before it goes to procurement, and make part substitution calls knowing exactly what breaks when a line changes&lt;/li&gt; &lt;li&gt;Hold OEMs and integrators (NVIDIA, Dell, Lenovo, Supermicro and others) to their technical commitments, from FAT witness through to on-site issue resolution&lt;/li&gt; &lt;li&gt;Build the reference designs and building blocks that mean each new deployment starts from a known-good baseline rather than a blank page&lt;/li&gt; &lt;/ul&gt; &lt;p&gt;&lt;strong&gt;ABOUT YOU&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;We care more about how you think and work than a perfect CV. You’ll likely bring a combination of the following:&lt;/p&gt; &lt;p&gt;&lt;em&gt;Essential:&lt;/em&gt;&lt;/p&gt; &lt;ul&gt; &lt;li&gt;You’ve designed and delivered large-scale GPU or HPC clusters into live data centres, and you were on site for the build&lt;/li&gt; &lt;li&gt;Deep, practical knowledge of NVIDIA platforms (GB200/GB300 rack-scale and HGX H200/B200) and what each one demands of a facility&lt;/li&gt; &lt;li&gt;Cluster-scale InfiniBand and Ethernet fabric design: topology, rail optimisation, oversubscription, and cable and optic selection&lt;/li&gt; &lt;li&gt;Physical infrastructure design across power and redundancy, direct liquid cooling and CDUs, containment and achievable cable lengths&lt;/li&gt; &lt;li&gt;You know part numbers, what’s optional and what isn’t, and you can hold an OEM to account when their commitments slip&lt;/li&gt; &lt;/ul&gt; &lt;p&gt;&lt;em&gt;Nice to Have:&lt;/em&gt;&lt;/p&gt; &lt;ul&gt; &lt;li&gt;Factory integration and FAT experience, including holding a dispatch gate&lt;/li&gt; &lt;li&gt;Storage design for AI workloads (WEKA, VAST, DDN, Ceph or similar)&lt;/li&gt; &lt;li&gt;Deployments across multiple geographies and data centre operators, including sites requiring fit-out&lt;/li&gt; &lt;li&gt;Neocloud or hyperscale experience on compressed schedules&lt;/li&gt; &lt;/ul&gt; &lt;p&gt;&lt;strong&gt;WHAT WE OFFER&lt;/strong&gt;&lt;/p&gt; &lt;ul&gt; &lt;li&gt;Competitive salary and annual discretionary bonus scheme&lt;/li&gt; &lt;li&gt;Employee wellbeing benefits&lt;/li&gt; &lt;li&gt;25 days holiday, plus public holidays&lt;/li&gt; &lt;li&gt;Private Medical Insurance&lt;/li&gt; &lt;li&gt;Enhanced Pension Scheme&lt;/li&gt; &lt;li&gt;Flexible working arrangements (remote or hybrid, depending on role and location)&lt;/li&gt; &lt;li&gt;Real ownership and autonomy — the trust to take initiative and experiment&lt;/li&gt; &lt;li&gt;Visible, meaningful impact as we scale&lt;/li&gt; &lt;li&gt;Clear career progression in a high-growth company&lt;/li&gt; &lt;li&gt;A collaborative, international culture built on trust, transparency, and ownership&lt;/li&gt; &lt;li&gt;The chance to help shape NexGen Cloud’s team, culture, and future&lt;/li&gt; &lt;/ul&gt; &lt;p&gt;&lt;strong&gt;WHY APPLY&lt;/strong&gt;&lt;/p&gt; &lt;p&gt;We welcome applications from all backgrounds.
