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. ## Description 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 ## Related Videos - [Running Secure Life Science Research at Scale using Hybrid GPU HPC and Kubernetes 🧬](https://www.wearedevelopers.com/videos/100355-running-secure-life-science-research-at-scale-using-hybrid-gpu-hpc-and-kubernetes) - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [Docker Compose: Rediscovered](https://www.wearedevelopers.com/videos/1978-docker-compose-rediscovered) - [Your Next AI Needs 10,000 GPUs.
