# HPC Engineer

ABOUT NEXGEN CLOUD 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. 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. THE ROLE: HPC ENGINEER We’re deploying more and more large-scale NVIDIA GPU clusters connected by InfiniBand, and the gap between a cluster that’s built and one that delivers its expected training performance is where customer experience is won or lost. We’re hiring an HPC Engineer to close that gap: validating and tuning clusters before handover, then owning the HPC layer in production. This is a role for someone who follows a problem across GPUs, fabric, storage and software until it’s fixed rather than handing it off, who won’t sign off a cluster that isn’t read
