We are seeking an experienced and versatile Senior IT Engineer to provide on-site support and management of our IT systems during a short coverage period. This role will ensure the continued stability and security of our infrastructure while key team members are on leave.
The successful candidate will be a technically strong generalist with hands-on experience across servers, networking, desktop support, and IT security.

* Monitor and maintain IT security practices, including access control, antivirus, and vulnerability management.
* Support system upgrades, minor changes, and ensure all IT processes are documented accurately.
* Escalate and manage critical incidents where required to minimise business disruption.
Requirements
* Proven experience in a senior IT engineering or infrastructure support role.
* Strong working knowledge of Windows Server environments and virtualisation platforms.
* Proficiency in desktop support and troubleshooting across Windows environments.
* Sound understanding of networking fundamentals (TCP/IP, VLANs, VPNs, firewalls).
* Experience implementing and maintaining IT security controls.
* Excellent problem-solving and communication skills, with the ability to work autonomously.
* Available to work on-site in Croydon daily from 14th – 21st November 2025.
