Help Desk Technician Tier II

The Help Desk Tier II Technician is a mid-level technical role responsible for resolving more complex end-user and system issues, supporting assigned primary clients, and serving as a key escalation point for Help Desk Tier I.

This role is focused on deeper technical troubleshooting, ownership of client environments, and delivering consistent, high-quality support across a wide range of technologies. The Help Desk Tier II Technician operates with a higher level of autonomy, judgment, and technical capability, ensuring issues are resolved efficiently while maintaining strong communication with clients and internal teams.

Tier II Technicians are not primarily responsible for live answer phone support; however, they may assist as needed during periods of high volume or team coverage gaps. Their primary focus remains on ticket-based work, escalations, and proactive engagement with their assigned clients to ensure stability and a strong overall service experience.
