Johannesburg, Gauteng, South Africa Edge Executives Full time R850 000 - R1 350 000 per year

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.
