Sentar is seeking an Action Officer in Charleston, SC!

This role is embedded within the Naval Information Warfare Center (NIWC) Atlantic's Defensive Cyberspace Operations (DCO) Integrated Product Team (IPT), which is tasked with safeguarding DHA’s global infrastructure against cyber threats, unauthorized access, and emerging vulnerabilities.

As part of the CyOC team, the Action Officer serves as a key operational resource, working directly with DHA subscribers to receive, triage, and respond to Requests for Information (RFIs) related to cybersecurity threats and incidents. This includes performing detailed threat analysis, coordinating with cross-functional intelligence teams, and delivering actionable intelligence reports to bolster the defense posture of supported entities.

Analysts in this role serve on the front lines of cyber defense, translating raw threat data and subscriber inquiries into strategic insights. By supporting frontline military medical operations and critical DoD health IT systems, the RFI Analyst plays a direct role in ensuring mission continuity, data protection, and the safety of warfighters and beneficiaries alike.

  • Collaborate with internal CyOC analysts, incident responders, and threat intelligence teams to ensure comprehensive RFI responses.
  • 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.
