Job description

ABOUT NEXGEN CLOUD:

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.

THE ROLE: Infrastructure Operations Engineer

This role exists because our platform is scaling quickly — and complexity comes with it. As we expand our OpenStack and Kubernetes environments globally, we need engineers who can take real ownership of how the platform is designed, operated, and improved. You'll have direct ownership over business-critical infrastructure that impacts performance, reliability, and customer experience.

This is not a maintenance role. If you like solving hard problems, owning systems end-to-end, and seeing the impact of your work immediately — you'll enjoy this.

WHAT YOU'LL BE DOING:

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

• 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

ABOUT YOU:

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

Essential

• Extensive hands-on Linux systems administration skills and knowledge — genuine depth, not surface-level familiarity
• Strong, proven experience building servers and racks — you've physically assembled, cabled, and commissioned hardware, not just specified or overseen it
• Direct hands-on experience physically working in data centres — you've personally stacked and racked hardware on-site
• A willingness and ability to travel to Quebec sites as required
• A solid understanding of networking and storage systems

Nice to Have

• Experience installing, racking, and configuring GPU hardware specifically, ideally including NVIDIA platforms
• Production experience running OpenStack and/or Kubernetes at scale
• Experience with infrastructure automation, CI/CD, and Git-based workflows
• Broader exposure to HPC or large-scale compute environments
• Contributions to open-source projects

WHAT WE OFFER:

• 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
