Enterprise Security Architect III

The Enterprise Security Architect III will design, develop, and maintain security architecture and application components supporting an assigned ICAM workstream.

The role combines enterprise security architecture with practical delivery responsibilities, including integration of security controls, security assessment support, Authorization to Operate activities, vulnerability remediation, POA&M management, and participation in application development, integration, and testing.

This position is best suited to a hands-on security architect who can work directly with software engineers, testers, DevSecOps personnel, system owners, and federal security stakeholders.

It is not a governance-only or policy-only architecture role.
