Top Secret ISSO/Systems Security Engineer

Insight Global is seeking an ISSO / Systems Security Engineer based in Dahlgren, Virginia, to apply expert knowledge of the Risk Management Framework (RMF) and ensure the security and compliance of classified DoD information systems. This role requires an IT‑related bachelor’s degree, an active Top Secret clearance, and an IAM Level II certification, along with 5+ years of experience as an ISSO supporting RMF and cybersecurity compliance within a classified DoD environment. The position includes oversight of authorized systems operating in Continuous Monitoring (ConMon) and support for a limited number of new systems through the RMF lifecycle from assessment through authorization.
The ISSO conducts detailed analysis of vulnerability and compliance scan results to identify risk trends, reviews STIG checklists and security artifacts prepared by ISSEs, and coordinates vulnerability scanning and compliance reporting through approved government tools and workflows such as eMASS. The role maintains and reviews RMF documentation, including System Security Plans (SSPs), Security Assessment results, and Plans of Action and Milestones (POA&Ms), ensuring findings are accurately risk‑rated, clearly documented, tracked through remediation, and defensible for government review. The ISSO collaborates closely with ISSEs, fellow ISSOs, and government stakeholders to ensure RMF artifacts are complete, consistent, and submission‑ready. The salary for this role ranges from $135,000–$145,000, based on experience.
