This is a hands-on operational role focused on implementing network changes, upgrades and patching during planned overnight maintenance windows.

Key Responsibilities

• Execute network patching, upgrades and vulnerability remediation activities.
• Implement approved infrastructure changes during overnight maintenance windows.
• Perform pre- and post-change checks and validation testing.
• Troubleshoot issues arising from patching and upgrades.
• Maintain change records and handover documentation.

• Strong enterprise networking experience, particularly Cisco routing and switching.
• Hands-on experience with Cisco IOS-XE, Cisco Nexus and Cisco UCS.
• Proven experience implementing changes and upgrades in live production environments.
• Understanding of ITIL change management and rollback procedures.
• Strong troubleshooting and documentation skills.

Experience within utilities, energy or critical infrastructure environments would be advantageous, as would Cisco certifications.
