• Monitor platform health, capacity and performance.
• Provide L2/L3 support for complex infrastructure incidents and lead root cause analysis.
• Maintain operational documentation, runbooks and technical procedures.

ABOUT YOU

• Strong hands‑on Linux/Unix server administration experience within enterprise or managed services environments.
• Deep expertise in Red Hat Enterprise Linux (RHEL) or Oracle Linux.
• Experience with at least one additional Unix platform such as AIX, Solaris or HP-UX.
• Strong understanding of TCP/IP networking, DNS, DHCP, NFS and enterprise storage technologies.
• Scripting and automation capability using Bash, Python or Perl.
• Experience with enterprise virtualisation platforms such as VMware vSphere, KVM or OVM.
• Familiarity with ITIL‑aligned incident, change and problem management processes.
• Strong analytical and troubleshooting capability.
• Excellent communication skills and confidence working directly with clients.

Experience with Oracle Cloud Infrastructure across Compute, Networking, Storage and IAM will be highly regarded. Exposure to Oracle Engineered Systems such as Exadata, Oracle Database Appliance or SPARC SuperCluster, as well as Terraform and Ansible, would also be advantageous.

Relevant Oracle Cloud, Red Hat, Oracle Linux or ITIL certifications will also be viewed favourably.
