CGI Federal is hiring an SME‑level Information System Security Officer (ISSO) for FIPS 199 moderate‑ to high‑impact cloud systems (IaaS, PaaS, or SaaS) to work with a skilled and motivated team of professionals on a high‑visibility Department of Homeland Security (DHS) Cybersecurity and Infrastructure Security Agency (CISA) cybersecurity program.

• Participate in Change Control Boards (CCB) and provide analysis and recommendations based on changes affecting the system’s security posture.
