Are you passionate about building resilient infrastructure, solving complex technical challenges, and shaping the future of technology platforms? Join an engineering-focused organisation where your ideas matter, your expertise is valued, and your work has a direct impact on educators, learners, and researchers nationwide.

We’re looking for a Senior Systems Administrator to join one of our key clients, to play a key role in designing, operating and improving our mission-critical virtualisation platforms and systems.

• Managing and enhancing virtual and physical infrastructure across the datacentres.
• Leading VMware and NSX deployment, optimisation, and improvements.
• Implementing automation to ensure our environments are scalable, efficient and secure.

• Enhancing tools and services used by other internal teams.

• Helping deliver large-scale services such as identity and access management, Wi-Fi roaming, high-capacity file transfers and rich media streaming.
• Ensuring these services are performant, secure, and built on modern, reliable infrastructure.
• You’ll also guide colleagues, influence architectural decisions, document systems, participate in on-call rotations, and help maintain high-quality operational standards.

• Proven experience building and maintaining VMware ecosystems (including stretched clusters and NSX).
• Strong understanding of network protocols and infrastructure, especially BGP and VXLAN.
• Deep Linux systems administration expertise (HA, LAMP, scripting, configuration).
• Solid knowledge of firewalls, routing, and load balancers.
• Comfortable with automation and configuration management tools.
• Collaborative team mindset and a desire to share knowledge.
• Willingness to join the on-call rotation (with additional compensation).

• Kubernetes or Rancher experience.
• Percona/MySQL database administration.
• Cloud platform experience (Azure, AWS).
