Lead Infrastructure Engineer

Lead Infrastructure Engineer (OpenStack)

Location: UK (Remote)

Department: Infrastructure

Reporting to: Head of Infrastructure

NexGen Cloud is the company behind Hyperstack, a full-stack AI cloud serving tens of thousands of customers from AI researchers to enterprises running the world's most compute-intensive workloads. We deliver on-demand and private GPU infrastructure to teams who treat performance as a requirement, not a feature.

We're a tight-knit, fast-moving team working at the cutting edge of AI cloud infrastructure. We practice what we preach, equipping our people with AI at every level so we can solve harder problems, ship faster, and keep raising the bar for what enterprise GPU infrastructure looks like.

This role exists because we are scaling Hyperstack rapidly to meet global demand for GPU-powered infrastructure across AI, ML, and HPC workloads. As our OpenStack and Kubernetes environments grow in complexity, we need strong technical leadership to keep everything stable, scalable, and moving forward. You'll have direct ownership over the performance, reliability, and evolution of our OpenStack and Kubernetes platforms in-region, while leading a small, high-calibre team of engineers.

This is a role for someone who leads from the front — hands-on when needed, but equally comfortable setting direction, making decisions, and holding the bar high.

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

• Own and drive the design, deployment, and operation of OpenStack and Kubernetes clusters optimised for GPU workloads
• Lead and develop a team of 4–5 infrastructure engineers, setting clear direction and standards
• Build and improve infrastructure through automation — IaC, GitOps, and CI/CD pipelines
• Ensure platform reliability through strong monitoring, observability, and incident management practices
• Collaborate closely with DevOps, Product, and Support teams to align infrastructure with real-world customer needs
• Take ownership of operational governance including incident, problem, and change management
• Identify opportunities to simplify, standardise, and scale systems as the platform grows
• Communicate clearly with leadership on platform performance, risks, and improvements

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

• Strong hands-on experience operating OpenStack in production environments
• Experience running production-grade Kubernetes clusters — ideally bare-metal or private cloud
• Solid Linux, networking, and storage fundamentals with a pragmatic troubleshooting approach
• Experience with infrastructure automation, CI/CD, and Git-based workflows
• Proven leadership or mentoring experience within infrastructure or platform teams
• Experience managing incidents and coordinating response during critical service events
• Strong communication skills, particularly translating technical issues for non-technical stakeholders

• Experience integrating Kubernetes with OpenStack
• Exposure to GPU infrastructure, HPC, or large-scale compute platforms
• Familiarity with advanced networking or cloud-native ecosystems
• Contributions to open-source or cloud-native communities

• Competitive salary and annual discretionary bonus scheme
• Employee wellbeing benefits
• 25 days of holiday, plus public holidays
• Flexible working arrangements (remote or hybrid, depending on role and location)
• Real ownership and autonomy, with the trust to take initiative and experiment
• The opportunity to make a visible, meaningful impact as we scale
• Clear career progression and growth opportunities in a fast-growing company
• A collaborative, international culture built on trust, transparency, and ownership
• The chance to help shape NexGen Cloud's team, culture, and future alongside ambitious, mission-driven colleagues
