  • Maintain Azure networking — VNets, NSGs, Azure Firewall, Private Endpoints
  • Configure management groups, subscriptions, policies, RBAC, and tagging
  • Deploy monitoring/alerting via Azure Monitor, Log Analytics, and Microsoft Sentinel
  • Execute cloud migrations (Azure Migrate, rehosting, re-platforming)
  • Implement hybrid connectivity (ExpressRoute, Site-to-Site VPN, Azure Arc)

Automation & Documentation

  • Maintain PowerShell automation/scripting to support repeatable delivery
  • Build and reuse infrastructure-as-code templates
  • Produce accurate as-built documentation and knowledge transfer material

Team Contribution

  • Share knowledge and contribute to the technical capability of the team
  • Mentor junior engineers on build and deployment activities

Experience & Skills Required

  • 5+ years' hands-on experience building, deploying, and migrating IT infrastructure across on-premises and cloud environments
  • Deep expertise in Windows Server (2016/2019/2022) — AD DS, DNS, DHCP, Group Policy, server roles
  • Demonstrated experience deploying Azure Landing Zones and resources aligned to CAF/WAF
  • Hands-on Microsoft 365 deployment/migration experience (Exchange Online, Teams, SharePoint, Entra ID)
  • Experience with hybrid identity (Entra Cloud Sync / Azure AD Connect)

  • Experience with enterprise server hardware (Dell EMC, HPE, Lenovo, Cisco UCS)
  • Experience with storage hardware/platforms (SAN, NAS, iSCSI/Fibre Channel)
  • Experience with backup, replication, and disaster recovery technologies
  • Data centre experience — racking, cabling, hardware commissioning
  • Tertiary qualification in Computer Science, Information Technology, or a related field

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
