  • Strong experience with Splunk ITSI (service trees, KPIs, adaptive/time-based thresholds, NEAP tuning, Service Analyzer configuration)
  • Proven OpenShift/Kubernetes observability experience across control-plane metrics, events, logs, workload correlation, and capacity management
  • Hands-on experience with telemetry pipelines (OpenTelemetry/OTLP, Prometheus exporters, Fluentd/Fluent Bit/Vector, Kafka with TLS, HEC/UF/DS onboarding)
  • Strong understanding of reliability engineering principles (golden signals, SLO design, namespace/application KPI mapping)
  • Experience optimising performance and licensing costs using workload rules, DMA, and summary indexing
  • Solid security and compliance knowledge (TLS/mTLS, certificate/token hygiene, PII controls, auditability, role/index mapping)
