The Information System Security Engineer (ISSE) will provide support to system owners for all assigned systems throughout their entire lifecycle following FIPS-199 and NIST SP 800-53.

• Direct the selection, tailoring, and documentation of security controls aligned with system categorizations, Agency risk appetite, and compliance requirements.
• Oversee the implementation of technical, operational, and management controls throughout system and application lifecycles, with a particular focus on quality and completeness of all deliverables.
• Ensure comprehensive security control assessments are planned, executed, and documented to validate the effectiveness of implemented safeguards.
• Prepare risk management documentation for system authorization and executive decision-making.
• Direct ongoing monitoring and continuous assessment activities, collecting metrics to adjust security strategies and ensure sustained compliance.
• Serve as a principal technical advisor on cybersecurity, bringing subject-matter expertise to risk analysis, incident response, system remediation, and audit support efforts.
• Foster a culture of security awareness, providing technical guidance and training to both team members and stakeholders.
• Track, report, and communicate status, risks, and improvement opportunities related to security engineering activities to leadership and stakeholders.
• Maintain up-to-date knowledge of RMF, NIST guidance, and industry best practices in support of continuous process improvement.

• Advisory and security design role in planned future IT solutions
• Close integration with system technical personnel to build required security configurations (centralized logging, MFA, vulnerability remediation)
• Emphasis on achieving new system ATO in a timely fashion
• Emphasis on closing technical security gaps
