Location: UK-based — Customer-Site Travel Required
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.
We’re a tight-knit, fast-moving team working at the cutting edge of AI cloud infrastructure. We practise 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.
This role exists because our pipeline of technically complex, high-value GPU cloud opportunities is growing — and winning them
requires more than a great sales team. The Solutions Architect sits at the intersection of sales, infrastructure, and the
customer, translating complex workload requirements into technically sound, commercially viable solutions on the Hyperstack
platform.
You’ll be the primary technical authority through the sales cycle: engaging directly with prospective and existing customers,
producing detailed solution designs, and ensuring that what is proposed can actually be delivered to the standard committed. This
is a role for someone who is equally comfortable in a customer meeting and a technical design review — someone who earns trust
through depth, not slides.
Rather than a long checklist, here’s what success in this role looks like:
handover — acting as the primary technical authority for GPU cloud solution design.
commercial objectives, producing detailed solution designs including architecture diagrams, network topology, storage
configurations, and GPU resource allocation models.
feasibility before commitments are made to customers.
rendering workloads — accelerating the sales cycle and improving proposal consistency across the team.
scoping, realistic estimates, and honest risk assessments.
provisioning, and margin review.
Hyperstack product roadmap.
We’re more interested in how you think and work than in a perfect CV. You’ll likely come from an HPC, AI infrastructure, or
high-performance cloud background and bring a combination of the following:
configuration (SLURM, PBS, or equivalent), MPI/NCCL tuning, and distributed training frameworks such as PyTorch, JAX, or
DeepSpeed.
AI training and inference workloads reliably in production.
bottleneck identification, and performance tuning at both the application and infrastructure layer.
container-native workload management.
design-to-deployment lifecycle for GPU-accelerated workloads.
board-level audiences.
software and performance trade-offs into clear, actionable decisions.
good looks like across different GPU generations and topologies.
and pipeline orchestration (Kubeflow, Airflow).
engage credibly with network and infrastructure teams on topology and tuning decisions.
technical role.
important opportunities.

HPC CLUSTER ARCHITECT Location: UK (Remote) Department: Infrastructure Reporting to: Head of Infrastructure ABOUT NEXGEN CLOUD: 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. 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. THE ROLE: HPC CLUSTER ARCHITECT This role exists because NexGen Cloud is winning large-scale dedicated GPU cluster contracts and needs someone who can own the full architecture cycle — from first customer conversation to production deployment. You'll have direct ownership over cluster architecture across compute, networking, storage, and physical design — translating customer requirements into production-ready, commercially optimised GPU deployments. This is a senior hands-on role for someone who has lived and breathed HPC cluster design and wants to be the technical authority, not one voice in a committee. You'll own designs end-to-end and see them go live. WHAT YOU'LL BE DOING: Rather than a long checklist, here's what success in this role looks like: * Own end-to-end cluster architecture for large-scale NVIDIA GPU deployments — from customer requirement through rack layouts, BOM, power and cooling design, to production handover * Design high-performance network fabrics across compute (InfiniBand, RDMA, NVLink/NVSwitch), storage, and WAN — defining topology, oversubscription models, and scaling strategies * Engage directly with OEMs and vendors — validating hardware configurations, reviewing quotes, and ensuring designs are both technically sound and commercially optimised * Provide technical oversight during deployment and bring-up — supporting hardware validation, performance testing, and acting as escalation point for complex integration issues * Act as a senior technical leader across Solutions Architecture, Cloud Engineering, and data centre partners — contributing to standardised reference designs and building out the HPC engineering function ABOUT YOU: We're more interested in how you think and work than in a perfect CV. You'll likely bring a combination of the following: * Proven experience in HPC or AI software stack design and delivery at scale — including workload profiling, scheduler configuration (SLURM, PBS, or equivalent), MPI/NCCL tuning, and distributed training frameworks such as PyTorch, JAX, or DeepSpeed. * Deep understanding of GPU software environments: CUDA, cuDNN, NCCL, driver stacks, and the tooling required to run large-scale AI training and inference workloads reliably in production. * Hands-on experience optimising AI and HPC workloads across multi-GPU and multi-node configurations — including profiling, bottleneck identification, and performance tuning at both the application and infrastructure layer. * Strong working knowledge of containerisation and orchestration in HPC/AI contexts: Docker, Kubernetes, NVIDIA GPU Operator, and container-native workload management. * Background in an OEM, hyperscaler, neo-cloud, or enterprise/research HPC environment, with demonstrable exposure to the full design-to-deployment lifecycle for GPU-accelerated workloads. * Ability to produce clear, professional technical documentation and architecture diagrams suitable for both engineering and board-level audiences. * Confident engaging with customers, vendors, and internal engineering teams as a technical authority — able to translate complex software and performance trade-offs into clear, actionable decisions. Nice to Have * Experience with large-scale cluster performance benchmarking — NCCL tests, MLPerf, or equivalent — and familiarity with what good looks like across different GPU generations and topologies. * Exposure to MLOps tooling and AI platform layers: experiment tracking (MLflow, W&B), model serving frameworks (Triton, vLLM), and pipeline orchestration (Kubeflow, Airflow). * Familiarity with InfiniBand and high-performance networking as it relates to distributed training performance — sufficient to engage credibly with network and infrastructure teams on topology and tuning decisions. WHAT WE OFFER: * Competitive salary and annual discretionary bonus scheme * Employee wellbeing benefits * 25 days of holiday, plus public holidays * Flexible working arrangements (remote or hybrid, depending on role and location) * Real ownership and autonomy, with the trust to take initiative and experiment * The opportunity to make a visible, meaningful impact as we scale * Clear career progression and growth opportunities in a fast-growing company * A collaborative, international culture built on trust, transparency, and ownership * The chance to help shape NexGen Cloud's team, culture, and future alongside ambitious, mission-driven colleagues MORE INFORMATION Head over to our NexGen Cloud careers page to view current openings and follow us on LinkedIn and X to learn more about our journey, newest releases and hear exciting news in the neocloud space.
