Senior 3rd Line Support Engineer
Solihull (Hybrid – 3 to 4 days onsite)
The Role
We’re looking for an experienced Senior 3rd Line Support Engineer to join a high-performing technical team based in Solihull.
This is a true 3rd line position, where you’ll act as the final escalation point for complex technical issues. You’ll take ownership of incidents end-to-end, focusing on deep technical investigation, root cause analysis, and delivering long-term solutions—not just quick fixes.
Working across modern on-prem, virtualised, and cloud environments, you’ll support a wide variety of technologies while also contributing to continuous improvement and mentoring junior engineers.
What You’ll Be Doing
- Acting as the technical escalation point for 1st and 2nd Line teams
- Owning and resolving complex incidents and problems through to completion
- Performing in-depth troubleshooting across infrastructure, cloud, and EUC environments
- Conducting root cause analysis and implementing permanent fixes
- Supporting users via tickets, phone, email, and remote sessions
- Managing and prioritising workload in line with SLAs
- Monitoring and responding to alerts from RMM tools
- Maintaining clear and accurate documentation and knowledge articles
- Identifying trends and driving service improvements
- Supporting internal initiatives to improve tools, processes, and standards
- Communicating effectively, translating technical detail into clear, business-friendly language
