About The Role

The Tier 4 IT Support / NOC Engineer is the final and highest level of technical escalation within the organization, positioned above Tier 3. This role owns the resolution of the most complex, highest-impact, and highest-visibility cases, including escalations from VIP accounts, Brand Managers, and client executives. Tier 4 acts as the technical authority and mentor across the support organization, providing real-time assistance to Tier 2 agents when Tier 3 is unable to resolve an issue, and to Tier 3 Engineers and the Brand Management team on an ongoing basis.

Beyond reactive escalation handling, this role carries strategic responsibility for special projects (site planning, design, and deployment), brand relationship coordination, and deep technical analysis of infrastructure health using SNMP data, application logs, and syslogs. Tier 4 partners closely with Network Engineering, ERT, Installs, Logistics, and equipment vendors to ensure new technologies are integrated smoothly into the production network.
