If you enjoy hands-on infrastructure work where you're trusted to solve the tougher problems, this is a brilliant opportunity. Our client is hiring for a reputed client to join a secure IT team on a full-time, fully onsite basis. You'll bring strong expertise across Windows, Linux, virtualisation, storage, backup, monitoring and Microsoft Active Directory-helping keep critical systems stable, secure and moving forward to newer technology.

What you'll be doing:

• Act as a third-line escalation point for complex infrastructure and Active Directory incidents, driving cases through to resolution
• Support both second-line incidents and requests when needed, with a structured troubleshooting approach
• Administer and maintain on-premises Active Directory, including Group Policy, DNS, DHCP, replication, trusts, authentication, plus Windows PKI and privileged access with health checks and remediation
• Deliver lifecycle work: builds, patching/upgrades, vulnerability remediation, and addressing ageing/out-of-support platforms
• Support modernisation and obsolescence projects, including moves towards newer Windows Server and RHEL/virtualisation/HCI-related platforms
• Lead root cause analysis for recurring or high-impact faults across connected layers
• Plan and deliver change/project work: testing, implementation, back-out planning and service transition
• Maintain documentation and records within ITIL Incident, Problem, Change and Configuration Management processes
• Contribute to out-of-hours support when required

What you'll bring:

• Experience supporting infrastructure at third-line level in a medium/large enterprise, with comfort stepping into second-line when required
• Strong depth either in core infrastructure or Active Directory, with genuine hands-on ability in the other
• Hands-on working knowledge across Windows Server 2016 onwards, VMware vSphere and/or Hyper-V, clustering/HCI, and SAN/NAS storage, backup and disaster recovery
• Familiarity with SCCM, WSUS and monitoring (including capacity, resilience and DR)
• Working knowledge of RHEL (or similar) for routine administration/patching/troubleshooting, plus networking basics (TCP/IP, DNS, firewalls, ports and routing)
• A UK citizen holding current Q2 clearance (essential)-no consideration without it
• Clear communication and documentation skills, with a calm, controlled approach in secure IT environments
