L2 Service Desk Engineer

The Role

The L2 Service Desk Engineer is accountable for resolving complex incidents that exceed L1 scope and for restoring service where deeper technical analysis is required. The role exists to diagnose root causes, apply advanced troubleshooting, and stabilise client environments while maintaining clear communication and accurate technical records.

The role strengthens the service system by mentoring L1 engineers, improving resolution approaches, and building high-quality knowledge that reduces repeat incidents and unnecessary escalation. Decisions made at L2 directly influence service stability, team capability, and client confidence.
