The posting

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: Network Engineer

We're deploying GPU infrastructure across multiple sites at increasing speed, and every deployment needs a complete network design from customer requirement through to physical build and handover. Right now that work sits with a small number of senior staff, which caps how many deployments can move at once — we need someone who can own that lifecycle end-to-end and run five or more of them at a time.

This is a role for someone who's comfortable owning a design from a customer's first requirement through to a validated handover, who can coordinate a build they're not physically present for, and who'd rather pick the right vendor for the problem than default to one stack.

WHAT YOU'LL BE DOING

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

  • Own network design end-to-end for GPU deployments, from customer requirements to handover
  • Turn customer requirements — BGP, IP addressing, firewalls, connectivity — into buildable cable and rack plans
  • Coordinate third-party deployment partners on physical build and validate their work remotely before sign-off
  • Run five or more concurrent deployments at once, each on its own timeline
  • Resolve network issues that surface post-deployment, through to full customer handover
  • Pick the right vendor and technology for each deployment instead of forcing one stack everywhere

ABOUT YOU

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

Essential:

  • Broad, multi-vendor network engineering experience, including Cisco — not single-vendor depth alone
  • Has taken network projects from customer requirement through design, build coordination, and handover, with hands-on implementation experience
  • Strong customer-facing technical communication — able to gather requirements and translate them into actionable designs
  • Proven ability to run multiple concurrent deployments remotely, coordinating third-party build partners without being on site
  • EVPN
  • VXLAN

Nice to Have:

  • Exposure to NVIDIA, Arista, FortiGate, or Juniper — Arista in particular
  • OpenStack Neutron networking background
  • Experience at an MSP, ISP, colocation or cloud provider, or systems integrator delivering end-to-end network deployments

WHAT WE OFFER

  • Competitive salary and annual discretionary bonus scheme
  • Employee wellbeing benefits
  • 25 days holiday, plus public holidays
  • 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.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
