Drive proactive and intelligent capacity management using forecasting, reservations, workload prioritization, and automated response to demand and failure scenarios. Partner with compute, traffic, networking, storage, and application leaders to enable safe zone evacuation, regional failover, and surge readiness. Observability, Testing & Reliability Intelligence Partner with Observability and TestOps leaders to integrate logs, metrics, traces, continuous profiling, testing, and incident intelligence into one reliability feedback loop. Ensure every critical service has actionable telemetry, meaningful SLOs, release-quality signals, and production-readiness evidence. Use production incidents and operational patterns to drive targeted integration, load, resilience, and regression testing. Establish executive reliability dashboards that provide trusted views of service health, risk, capacity, and operational effectiveness.

Escalation Handling: Act as the first point of escalation for complex cases. Support agents in making "tough calls" regarding inventory deactivation or seller rejections. Process Feedback Loop: Identify recurring operational bottlenecks and provide feedback to the L5 Manager and Policy teams to refine Standard Operating Procedures (SOPs). Essential Qualifications Experience: Minimum 2–3 years of experience in people management or team leadership within a contact center, shared service, or high-volume operations environment.
