About the role

Key responsibilities & impact

Analyze emerging threats, campaigns, intrusion data, and malware execution telemetry to identify detectable behaviors and coverage gaps
Author and optimize behavioral detection rules (Indicators of Attack) targeting adversary techniques observed on Windows endpoints
Query and analyze endpoint telemetry (process execution, file system, registry, memory, authentication events) to validate detection hypotheses and assess coverage
Monitor detection precision metrics, investigate false positives, and tune detections to maintain high signal-to-noise ratios
Manage detections through a structured lifecycle: development, validation, staged deployment, and production monitoring
Collaborate with threat intelligence and incident response teams to prioritize detection development based on active threat campaigns
