  • Maintain situational awareness of current and emerging cyber threats, vulnerabilities, and attack techniques.
  • Support the development, documentation, and refinement of RFI processing workflows and standard operating procedures (SOPs).
  • Provide technical guidance to subscribers regarding cyber threat mitigation and security best practices.
  • Track RFI status, metrics, and trends to support operational reporting and performance improvement.
  • Coordinate with NIWC Atlantic and DHA stakeholders to ensure mission alignment and timely response to critical intelligence needs.
  • Operate in a high-tempo environment with competing priorities and rapidly evolving threat landscapes.

  • Proficiency in analyzing cyber threats across the MITRE ATT&CK framework, including TTPs and IOCs
  • Experience with threat intelligence platforms (TIPs), SIEM tools (e.g., Splunk, ELK, QRadar), and open-source intelligence (OSINT) research tools
  • Familiarity with malware analysis, DDoS patterns, phishing campaign forensics, and adversarial behavior
  • Strong written and verbal communication skills, including the ability to draft and present technical intelligence reports to varied audience.
  • Ability to manage and prioritize multiple concurrent RFIs in a high-tempo operations environment
  • Working knowledge of network architecture and protocols, including TCP/IP, DNS, HTTP/S, SMTP, and common intrusion methods
