About the Role:

The Senior NOC Engineer III (Contact Center) is a senior individual contributor and final technical escalation for complex incidents and chronic problems, executing advanced diagnostics across network, server, cloud, and backup platforms, and driving root cause analysis and problem management in client environments. They implement approved standards or emergency changes during maintenance windows in alignment with ITIL/CAB processes and ServiceNow workflows and use LogicMonitor to validate and refine alerting effectiveness.

The Senior Engineer mentors lower tiers, advances automation, and authors/maintains SOPs, runbooks, and knowledge articles while engaging directly with clients as needed to communicate status and ensure SLA and MTTR objectives are met within a 24x7 operations model. 

What You'll Do:

• Act as the final technical escalation for P1/P2 incidents, run the technical bridge to stabilize service, define targeted workarounds, and deliver complete postincident remediation plans. 
• Lead deepdive diagnostics across network, server, storage, virtualization, cloud, and/or backup platforms, correlating logs, traces, packet captures, and platform telemetry to isolate root cause with high confidence. 
• Own problem management for chronic issues, producing RCAs and known error records, defining preventative actions, and tracking systemic fixes to closure in ServiceNow. 
• Engineer and execute complex/highrisk changes, including risk/impact analysis, MOP authoring, pre/post validation, and backout plans; improve change success by templating repeatable patterns aligned to CAB policy. 
• Elevate monitoring/observability, assist with designing monitoring thresholds, event correlation, custom metrics, and dashboards that reduce alert noise and improve time to detect for critical services. 
• Build and harden operational automation (PowerShell/Python/Bash and platform APIs) to accelerate diagnostics, remediation, compliance checks, and recurring maintenance, and package it for safe use by lower tiers. 
• Serve as a subjectmatter expert and vendor/TAC coordinator, unblocking complex technical issues and integrating vendor guidance into durable, documented fixes. 
• Raise the quality bar for operational content, authoring, and reviewing Tier 1/2ready SOPs, runbooks, and KBs; ensure artifacts are updated after incidents and changes and remain auditready in the central repository. 
• Uphold ITIL discipline in ServiceNow, maintaining exemplary ticket hygiene, CI relationships, clientfacing communications, and complete Incident/Change/Problem/Knowledge records within a 24x7 model. 
• Support 24x7 operation through oncall participation and afterhours maintenance/emergency changes to ensure continuity of care.
