• Troubleshoot complex storage, backup and connectivity issues across Linux, Windows and virtualised environments.
• Manage storage provisioning, migrations, upgrades, replication, backup, restore and disaster-recovery activities.
• Develop scripts and automation to improve operational efficiency, consistency and platform reliability.
• Maintain technical documentation and collaborate with infrastructure, application and vendor teams on projects and incidents.

What we’re looking for

Experience

• Strong hands-on experience administering both Storage Area Network (SAN) and Network Attached Storage (NAS) platforms within enterprise production environments.
• Experience administering Commvault or a comparable enterprise backup and recovery platform.
• Good working knowledge of Fibre Channel, iSCSI, NFS, SMB and storage integration with Linux and Windows.
• Experience supporting storage platforms within Openstack, VMware, Hyper‑V, Citrix or comparable virtualised environments.
• Strong systems‑engineering knowledge, including TCP/IP, DNS, high availability, disaster recovery and production incident management.
• Experience with technologies such as Netapp, Pure Storage, Dell Technologies or VAST Data, alongside SAN fabric administration, Fibre Channel switching, scripting or automation tools.

What We're Looking For

• A proactive approach to operational ownership, service improvement and risk reduction.
• Clear communication skills and the ability to work effectively across technical teams.
