Location: New York, San Francisco, Austin
Workplace: Onsite
Employment Type: Full time
Job Function: Cybersecurity

Key Responsibilities

  • •Track nation-state and advanced criminal actors, translating their tooling, infrastructure patterns, and tradecraft into intelligence that changes what the program detects and hunts for.
  • •Build and run pipelines that collect, enrich, and correlate indicators, then deliver them into detection and agentic triage systems for operational use.
  • •Drive intelligence-led hunts across enterprise, cloud, identity, data center IT, and OT telemetry, converting findings into high-fidelity detections authored as code.
  • •Perform hands-on malware, phishing-infrastructure, and attacker-tooling analysis to extract indicators, TTPs, and attribution signals feeding detection engineering and incident response.
  • •Curate inbound intelligence from commercial feeds, open source, government, and peer relationships; prioritize what matters for the program’s threat model and build intelligence-sharing relationships.
