  • City of London - Onsite 2/3 days a week
  • 6 month contract
  • Inside of IR35
  • £650 - £750 per day

We're seeking an experienced VDI Platform Engineer to support a medium-sized enterprise Omnissa (VMware) Horizon environment in a critical, high-impact setting.

This is a hands-on engineering role focused on the operation, stability, and continuous improvement of the VDI platform. You'll be working across core Horizon infrastructure and desktop delivery - not a helpdesk role, though some targeted user support may be required where issues relate directly to the platform.

What You'll Be Doing

  • Run and maintain the Horizon platform (pods, pools, brokers, gateways)
  • Manage VDI infrastructure in collaboration with platform teams (vSphere, storage, networking)
  • Monitor performance and capacity, troubleshooting issues end-to-end
  • Support incidents, problem management, and change activity
  • Manage desktop pools, golden images, and provisioning workflows
  • Support application delivery (App Volumes or similar) and user profile management (DEM or equivalent)
  • Troubleshoot Windows and Linux VDI session and performance issues
  • Support core Windows Server services (AD, DNS, authentication)
  • Contribute to patching, upgrades, and ongoing platform enhancements.

What We're Looking For

  • Strong hands-on experience with VMware / Omnissa Horizon
  • Live SC Clearance
  • Proven experience operating VDI in enterprise environments
  • Solid understanding of:
    • Horizon architecture (Connection Servers, UAG, pools, images)
    • vSphere (vCenter, ESXi)
    • VDI performance optimisation and troubleshooting
  • Strong Windows Server knowledge (AD, GPO, DNS, identity integration)
  • Experience supporting Windows and/or Linux VDI desktops
  • Excellent troubleshooting across platform, OS, and user experience
