Technical Lead – Systems & Storage, Managed Services

Responsibilities:

Incident Resolution & Escalation

• Act as the L3 escalation point for system and storage incidents that L2 engineers cannot resolve, and own them through to closure within SLA.

• Lead P1/P2 incidents end-to-end: run the technical bridge, make sound service-restoration decisions (workaround, failover, rollback) and keep clients and management updated at agreed intervals.

• Troubleshoot complex issues across the full stack: server hardware, storage arrays, SAN fabric, hypervisor, operating system, Active Directory / Microsoft workloads, Microsoft 365, backup and DR, Cloud infrastructure

Problem Management & Continuous Improvement

• Produce clear, client-ready Root Cause Analysis (RCA) reports for P1/P2 incidents, covering timeline, root cause, impact and preventive actions.

• Analyse ticket trends to find recurring incidents, then drive permanent fixes through configuration, firmware, design or monitoring changes.

• Review high-risk changes performed by the team (firmware upgrades, storage migrations, DR tests) and ensure each has proper testing and rollback plans.

• Improve monitoring and alerting so that issues are detected before clients raise them.

Technical Leadership

• Mentor and coach L2 engineers: guide them through live incidents, review their troubleshooting and raise team capability against our skills matrix.
