Head of Infrastructure

We are building next‑generation GPU cloud infrastructure. Nex Gen Cloud is the company behind Hyperstack, a high‑performance cloud platform designed for compute‑intensive workloads. Our customers include AI‑native companies, research teams and enterprises running complex, large‑scale models. Hyperstack powers everything from on‑demand GPU compute to private cloud environments — built for speed, control and reliability.

We’re a scale‑up by design — solving complex infrastructure challenges at pace, with real‑world impact.

This role exists because our platform is scaling quickly — and complexity comes with it.

As we expand our Open Stack and Kubernetes environments globally, we need engineers who can take real ownership of how the platform is designed, operated and improved. This is not a maintenance role.

You’ll be working on business‑critical infrastructure that directly impacts performance, reliability and customer experience. If you like solving hard problems, owning systems end‑to‑end, and seeing the impact of your work immediately — you’ll enjoy this.

• Own the design, deployment and operation of Open Stack and Kubernetes environments
• Ensure platform performance, scalability and resilience for GPU workloads

• Build and improve infrastructure using infrastructure‑as‑code and Git Ops practices
• Drive automation across provisioning, deployment and operational workflows

• Optimise GPU workload scheduling using Kubernetes and NVIDIA tooling
• Implement monitoring, logging and alerting to ensure platform stability
• Lead incident response and continuous improvement of reliability

• Maintain strong security controls across infrastructure and container layers
• Implement RBAC, network policies and tenant isolation

• Work closely with Platform, Dev Ops, AI, Product and Support teams
• Align infrastructure capabilities with customer and platform requirements

• Strong hands‑on experience running Open Stack in production environments
• Proven experience operating Kubernetes at scale (ideally bare‑metal or private cloud)
• Solid understanding of Linux, networking and storage systems
• Experience with infrastructure automation, CI/CD and Git‑based workflows

• Ability to troubleshoot complex infrastructure and performance issues
• Strong ownership mindset — comfortable operating without heavy oversight
• Ability to simplify and scale systems in a fast‑moving environment

• Experience integrating Kubernetes with Open Stack
• Exposure to GPU infrastructure, HPC or large‑scale compute environments
• Familiarity with advanced networking or cloud‑native ecosystems
• Contributions to open‑source projects

• Competitive salary + discretionary bonus
• 25 days holiday + public holidays
• Fully remote working (Australia‑based)
• High ownership and autonomy
• The chance to work on genuinely complex, high‑performance infrastructure
• Clear progression as the business scales

We’re not running standard cloud infrastructure.

We’re solving for performance, scale and efficiency in AI workloads — where the margin for error is small and the technical bar is high.

• Your work directly impacts customers
• You’ll own real systems, not just tickets
• And you’ll be trusted to make decisions, not wait for them
