[Hiring] Senior Infrastructure Engineer @NexGen Cloud

Role Description

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

Qualifications

• 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

Requirements

• 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

Benefits

• 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

• And you’ll be trusted to make decisions, not wait for them
