Information System Security Engineer (ISSO)

The Chief Information Office (CIO) is responsible for planning, maintaining, and sustaining the global CIO enterprise that supports critical national security missions. Through the SITE III multi-award IDIQ contract, the CIO delivers high-impact solutions that strengthen how the Defense Intelligence Agency operates today and prepares it for the future.

SITE III supports warfighters, policymakers, and acquisition leaders across the Defense Intelligence Enterprise (DIE) by delivering a decisive Information and Communications Technology (ICT) advantage. Our teams provide strategic, technical, and program management expertise to modernize enterprise infrastructure, systems, and applications—ensuring they are secure, resilient, and mission-ready.
