  • Manage server infrastructure (physical and virtual) including provisioning, patching, performance tuning, and decommissioning.
  • Administer cloud infrastructure across GCP, AWS, or Azure: compute, storage, networking, and IAM configurations.
  • 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.
  • Maintain infrastructure documentation: network diagrams, runbooks, configuration baselines, and change records.
  • Support IT security audits and contribute infrastructure evidence to compliance programmes (ISO 27001, SOC 2, PCI-DSS).
