• Support the full RMF A&A lifecycle to achieve and maintain the system Authority to Operate (ATO) with DOD. • Develop, author, and maintain all core A&A documentation (e.g., SSP, system diagrams, ConMon plans) within the system’s eMASS record, ensuring all controls, artifacts, and package details are accurate. • Coordinate with key stakeholders, including Information System Owners, ISSMs, external assessors, and the Authorizing Official Designated Representative (AODR), providing strategic guidance and responding to data requests to ensure the success of all Authorization to Operate (ATO) processes. • Conduct security assessments, including vulnerability scans, DISA STIG validation, and security control testing. Work with engineering and support teams to facilitate the remediation of identified vulnerabilities and Plans of Action and Milestones (POAMs). In all phases of the RMF process, work to eliminate manual processes with automation. • Perform continuous monitoring and incident response by leveraging SIEM tools (e.g., Splunk) for log analysis and dashboard creation, conducting vulnerability scans, proactively investigating potential threats, and updating all compliance documentation. • Administer and maintain enterprise security tools and platforms (e.g., SIEM, EDR, vulnerability scanners), ensuring operational integrity, scalability, and alignment with organizational security policies. • Provide technical and procedural guidance to engineering and operations staff to ensure secure system design, operation and automation tooling. • Prepare for and support government cybersecurity audits by staying current on all evolving DoD policies, including DFARS, CMMC, and NIST guidance. • Executed end-to-end incident response (IR) for cyber events, from initial detection and containment to eradication and recovery.
