• Active Directory, Group Policy, and core infrastructure services
• Networking fundamentals (TCP/IP, DNS, DHCP, VLANs, VPNs)
• Firewalls, switches, and general networking devices
• Virtualisation (VMware, Hyper-V, or similar)
• Microsoft Azure, including Azure Virtual Desktop (AVD/WVD)
• Citrix environments

Desirable

• Exposure to security tools or security-focused troubleshooting
• Scripting, automation, or Infrastructure as Code experience
• Experience mentoring or supporting junior engineers

What's in It for You

• Hybrid working - 3 - 4days per week in Solihull
• 25 days annual leave, increasing to 28 with service
• A strong healthcare and wellbeing package, including private medical cover, discounted health plans, and virtual GP access
• A comprehensive benefits package designed to support your health, wellbeing, and work-life balance
• Employee assistance programme and wellbeing support
• Real opportunities for career progression and technical development
• A collaborative environment where you can make a genuine impact

Why Apply?

This is a great opportunity for a seasoned 3rd Line Engineer who wants to:

• Work on complex, meaningful technical challenges
• Move beyond ticket resolution into true problem ownership
• Influence service delivery and continuous improvement
• Be part of a forward-thinking, supportive technical team
