Experience operating a modern detection stack at scale — SIEM/security data lake (e.g., Elastic, Splunk), streaming pipelines (e.g., Kafka, Flink), warehouse-based batch detections, EDR (e.g., CrowdStrike, SentinelOne), CNAPP/CDR (e.g., Wiz), identity providers (e.g., Okta), and SOAR/case management (e.g., Torq).
