  • Proactively identify and assess vulnerabilities in infrastructure and code, working with development and other cross functional teams to address issues.
  • Contribute to the end-to-end detection lifecycle: model attacker behaviors (MITRE ATT&CK), write and test detections as code across security programs and tooling (SentinelOne, Wiz, Okta, AWS CloudTrail), and continuously enrich to reduce false positives and improve MTTD. Support data quality and telemetry onboarding, maintain response playbooks, and provide threat validation assistance across the business.

  • Correlate endpoint and infrastructure telemetry to identify emerging threats. Curate and operationalize intelligence (IOCs, TTPs) into detections and response playbooks, and maintain vetted intelligence feeds.
  • Assist GRC initiatives by mapping controls to internal policies and frameworks (e.g., SOC 2, NIST CSF, NYC DFS 500), identifying gaps, supporting audits and evidence collection, tracking remediation, and maintaining policies and control documentation.
  • Work with engineering and business teams to champion security best practices, communic
