NexGen Cloud

Architect

• 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

HPC Cluster Architect

Infrastructure Engineer

• Own the design, deployment, and operation of OpenStack and Kubernetes environments — ensuring platform performance, scalability, and resilience for GPU workloads
• Build and improve infrastructure using infrastructure-as-code and GitOps practices, driving automation across provisioning, deployment, and operational workflows
• Optimise GPU workload scheduling using Kubernetes and NVIDIA tooling, and implement monitoring, logging, and alerting to ensure platform stability
• Lead incident response and drive continuous improvement of reliability across the platform
• Maintain strong security controls across infrastructure and container layers — RBAC, network policies, and tenant isolation
• Work closely with Platform, DevOps, AI, Product, and Support teams to align infrastructure capabilities with customer and platform requirements
