Description
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.
Key Responsibilities
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
What We’re Looking For
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.

About this role
NexGen Cloud is scaling its GPU cloud platform globally, and this role exists to handle the infrastructure complexity that comes with that growth. You'd own the design, deployment and operation of OpenStack and Kubernetes environments that power AI workloads for customers ranging from research teams to enterprises. This isn't a support or maintenance position — you'll be working on systems that directly affect platform performance, reliability and customer experience, with real autonomy to make decisions about how infrastructure is designed and improved.
The core of the work involves running production OpenStack and Kubernetes at scale, building automation and infrastructure-as-code to reduce manual work, optimizing GPU workload scheduling, and maintaining security and reliability across the platform. You'd also collaborate across teams to align infrastructure capabilities with what customers and the product need. The role calls for strong hands-on experience operating both OpenStack and Kubernetes in production, solid Linux and networking fundamentals, and comfort troubleshooting complex performance issues. Experience with GPU infrastructure, HPC or integrating Kubernetes with OpenStack would be valuable but isn't required.
This is a fully remote role based in Australia, offering competitive salary, bonus, 25 days holiday, and the kind of ownership that suits engineers who want to see the impact of their work immediately and prefer working on genuinely difficult infrastructure problems rather than standard cloud operations.
