About the role

Key responsibilities & impact

Tune EDR, SIEM, and XDR detections to reduce false positives and improve alert quality.
Build and maintain detection rules, correlation searches, dashboards, watchlists, and response workflows.
Translate Red Team, Purple Team, incident, and Threat Intelligence findings into repeatable defensive checks.
Validate that EDR policies, prevention rules, logging, sensor health, and response actions work as expected.
Review noisy alerts and tune thresholds, exclusions, lookups, entity context, and suppression logic.
Support SOC analysts with clear alert descriptions, triage steps, severity logic, and escalation guidance.
Improve log coverage, parsing, field normalization, enrichment, and data quality.
