• Commission new server rooms, including racks, hardware population and structured cabling
• Manage Dell servers, Windows Server and virtualisation (Hyper-V/VMware) across both environments
• Configure and maintain QNAP NAS storage
• Own backup and restore using Veeam - monitoring jobs, performing restores, and supporting active migrations
• Configure and troubleshoot Cisco Meraki networking (MX/MS/MR), including firewalls, VLANs and segmentation

• Mentor and upskill junior members of the in-house IT team, ensuring knowledge transfer ahead of handover

• Proven, senior-level experience as an Infrastructure Engineer within a mid-to-large, established organisation with complex, bespoke, or “grown organically” legacy environments
• Experience in a regulated sector (e.g. financial services, healthcare, life sciences or defence) with a solid understanding of handling sensitive data securely, particularly during data transfers
• Strong hands-on experience with Dell servers, Windows Server, Hyper-V/VMware, QNAP NAS and Cisco Meraki
• Solid networking fundamentals (TCP/IP, DNS, DHCP, routing, ACLs)
• Proven track record of physical infrastructure work: racking, cabling, and site relocations
• Experience with SaaS tenancy migrations and identity platforms (AD/Entra ID)
• Prior involvement in M&A, infrastructure transformation, or large-scale integration programmes is highly desirable
• A natural mentor - comfortable leading and upskilling less experienced colleagues without steamrolling them
• Calm, structured and professional under pressure - a safe pair of hands rather than a firefighter
