Senior Infrastructure Engineer (OpenStack) – Australia
Location: Australia (Remote) Department: Infrastructure Reports to: Head of Infrastructure
About NexGen Cloud & Hyperstack
We are building next-generation GPU cloud infrastructure.
NexGen 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.
The Role
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.
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.
Platform Ownership
Own the design, deployment and operation of OpenStack and Kubernetes environments
Ensure platform performance, scalability and resilience for GPU workloads
Infrastructure & Automation
Build and improve infrastructure using infrastructure-as-code and GitOps practices
Drive automation across provisioning, deployment and operational workflows
Performance & Reliability
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
Security & Architecture
Maintain strong security controls across infrastructure and container layers
Implement RBAC, network policies and tenant isolation
Cross-Functional Collaboration
Work closely with Platform, DevOps, AI, Product and Support teams
Align infrastructure capabilities with customer and platform requirements
Core Experience
Strong hands-on experience running OpenStack 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
Capabilities
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
Nice to Have (Not Essential)
Experience integrating Kubernetes with OpenStack
Exposure to GPU infrastructure, HPC or large-scale compute environments
Familiarity with advanced networking or cloud-native ecosystems
Contributions to open-source projects
What You’ll Get
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
Why NexGen Cloud
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.
This is a role where:
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
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.
