• Manage virtualisation platforms (VMware, Hyper-V) and containerisation environments where applicable.


• Implement and maintain backup and disaster recovery solutions; conduct periodic DR tests and document outcomes.


• Monitor infrastructure health using observability tools (e.g. Zabbix, Datadog, Grafana); respond to and resolve infrastructure incidents.


• Enforce infrastructure security controls: patch management, vulnerability remediation, access hardening, and certificate management.


• Manage on-premises and cloud storage solutions, ensuring data integrity, retention compliance, and performance.
