About the Role

The Falcon Complete Detection Engineering (FCDE) team builds and maintains the NG-SIEM detection ruleset that powers CrowdStrike's managed detection and response capability. The team develops high-fidelity detections driven by threat intelligence and real-world observations, including rapid response to zero-days and emerging threats, filling detection gaps across a broad range of third-party data sources where adversaries increasingly operate. FCDE also builds and refines AI-powered tooling to maximize the speed and fidelity of detection development at scale. Engineers collaborate across the full pipeline, from ingestion and parsing to response and automation, to improve triage efficiency and accelerate threat disruption.
