Job description

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: PRESALES ENGINEER

Hyperstack’s go-to-market is scaling across AI infrastructure and HPC, and the deals we’re working on now demand more technical depth: larger clusters, more complex architectures, and more stakeholders who need proof before they commit. You’ll sit between customers, Sales and Engineering, owning technical discovery, solution design and demos. You’ll also shape how pre-sales grows as the team does.

This role suits someone who is as comfortable in a deep architecture discussion as in a boardroom, and who measures themselves on deals won rather than demos delivered.

WHAT YOU’LL BE DOING

Rather than a checklist, here’s what success in this role actually looks like:

• Leading technical discovery and turning customers’ AI workloads into GPU cloud solutions, across training, inference, HPC and managed services
• Giving Sales and BD the technical validation, scoping and proposal input that moves deals forward
• Running demos, technical presentations and architecture workshops for prospects, partners and enterprise customers
• Building and maintaining the technical sales library: solution briefs, battlecards, architecture patterns and FAQs
• Turning competitive insight on hyperscalers and neoclouds into positioning Sales can use, and flagging risks such as capacity overcommitment before anything is promised to a customer
• Keeping Sales and Marketing current through regular enablement, and acting as a credible technical voice at meetups, webinars and events
• Feeding customer insight into Product and Engineering, and handing customers over cleanly into implementation

ABOUT YOU

We care more about how you think and work than a perfect CV. You’ll likely bring a combination of the following:

• 5+ years in presales, solutions engineering or technical consultancy within data centre, cloud or AI/GPU infrastructure
• A solid technical foundation across GPU infrastructure, data centre networking, cloud architecture and container orchestration, applied to AI training and inference at scale
• The ability to engage credibly on GPU cluster sizing, network fabric trade-offs such as InfiniBand vs RoCE, and model serving architecture
• Evidence of commercial impact, such as a contribution to win rates, deal size or conversion, not just demos delivered
• Clear communication with engineers and commercial buyers alike, adjusting depth without losing credibility

Nice to Have:

• Hands-on experience with NVIDIA-based AI solutions such as DGX or HGX, ideally backed by NVIDIA certifications
• Experience in a neocloud or GPU-as-a-Service environment
• Experience building pre-sales collateral from scratch in a scaling business

WHAT WE OFFER

Competitive salary and annual discretionary bonus scheme

• Private Medical Insurance
• Enhanced Pension Scheme
• Flexible working arrangements (remote or hybrid, depending on role and location)
• Real ownership and autonomy — the trust to take initiative and experiment
• Visible, meaningful impact as we scale
• Clear career progression in a high-growth company
• A collaborative, international culture built on trust, transparency, and ownership
• The chance to help shape NexGen Cloud’s team, culture, and future

WHY APPLY

We welcome applications from all backgrounds. If you enjoy solving complex infrastructure problems and want to build something meaningful at scale, we’d like to hear from you.
