Job Description

As a Senior Support Engineer, you’ll act as the final technical escalation point for complex incidents and problems. This is a true 3rd line role — you’ll be responsible for deep technical investigation, root cause analysis and driving permanent fixes, not just quick workarounds.

You’ll work across modern on‑prem, virtualised and cloud environments, supporting customers with a broad range of technologies. You’ll also play a key role in mentoring colleagues, improving service quality, and helping shape how we deliver support.

This role is based at our Solihull head office.

• Acting as the technical escalation point for 1st and 2nd line engineers
• Owning and resolving complex incidents and problems through to completion
• Providing expert support via tickets, telephone, email and remote access
• Performing in‑depth troubleshooting across infrastructure, cloud and EUC platforms
• Carrying out root cause analysis and recommending long‑term improvements
• Managing and prioritising multiple issues while working within SLA commitments
• Monitoring and responding to alerts generated by remote monitoring tools
• Maintaining accurate documentation, knowledge articles and customer records
• Identifying opportunities to reduce recurring incidents and improve service delivery
• Supporting continuous improvement initiatives across tools, processes and standards

Communicating clearly with customers, translating technical detail into business‑friendly language

Qualifications

You’ll be an experienced support professional with a strong technical background and the confidence to take ownership of challenging issues.

Essential experience includes:

• Proven experience in a senior / 3rd line IT support role, ideally within an MSP environment
• Windows desktop and server operating systems
• Microsoft 365 administration (Exchange Online, Intune, Entra ID/Azure AD)
• Server administration (Active Directory, Group Policy, core infrastructure services)
• Networking fundamentals: TCP/IP, DNS, DHCP, VLANs and VPN technologies
• Firewalls, switches and general network devices
• Virtualisation technologies (VMware, Hyper‑V or similar)
• Microsoft Azure, including virtual desktops (AVD/WVD)
• Citrix environments

Desirable (but not essential):

• Experience with security tooling or security‑focused troubleshooting
• Exposure to automation, scripting or infrastructure‑as‑code concepts
• Mentoring or coaching junior engineers
