IT Systems Administrator Location: South Africa (Hybrid/On-site as required) Type: Permanent Remuneration: Market-related Keep platforms stable. Automate, secure, and scale. About the Role Own core enterprise systems virtualisation, identity, collaboration, cloud, networking and backups. Blend 3rd-line administration with project delivery to improve reliability, security and cost efficiency. Who the Client Is A modern, cloud-forward enterprise with a mixed on-prem/Azure footprint, focused on uptime, security-by-default and pragmatic automation. What You’ll Do Administer and optimise VMware clusters (performance, capacity, patching). Manage Active Directory/Entra ID (users, GPOs, DNS/DHCP, hybrid identity, PKI). Operate Microsoft 365 (Exchange Online, SharePoint, Teams) and hybrid Exchange. Build/support Azure (VMs, storage, networking); enforce security and cost guardrails. Run Veeam backups/replication; test recoveries to agreed RPO/RTO. Oversee Cloudflare (DNS/WAF/CDN) and core network dependencies. Automate with PowerShell ; maintain CMDB and clean documentation. Perform health checks, patching and upgrades; follow ITIL for incidents/changes. Provide 3rd-line support and deliver improvement projects with peers. What You Bring 5–7 years’ systems admin experience across Windows/VMware/M365/Azure. Solid networking (TCP/IP, VLANs, VPNs), security basics and PKI. Proven PowerShell automation; scripting for scale and repeatability. Experience with Veeam (or similar) and DR testing. Clear communicator; structured, detail-driven and service-oriented. Relevant certs advantageous (e.g., VCP, AZ-104/305, MS-102). What Success Looks Like Stable, well-patched platforms with clear observability and low incident rates. Fast, reliable restores; DR tests passed to target RPO/RTO. Automated routines reducing toil and mean-time-to-resolve. Predictable costs across Azure/M365 with usage and savings tracked. Up-to-date runbooks and a knowledge-enabled support team. Realistic Preview: You’ll juggle BAU and projects in a live environment—after-hours maintenance windows and urgent escalations happen. The upside: visible impact on uptime, security and developer velocity. hiring edge kestria
