Expert Security Engineer

Purpose and Impact

As the Security Subject Matter Expert, you will serve as the critical bridge between high-level security policies and their technical implementation, driving the Risk Management Framework (RMF) and Assessment & Authorization (A&A) lifecycle across multiple applications. Your primary purpose is to ensure that system designs inherently meet rigorous security objectives by evaluating IT architectures, guiding development teams, and enforcing compliance with NIST SP 800-53 and enterprise standards from concept to deployment.

In this role, your work directly safeguards mission-critical systems and reduces organizational risk. By proactively identifying, tracking, and mitigating vulnerabilities through continuous monitoring, STIG enforcement, and POA&M management, you ensure the resilience of enterprise capabilities. Your leadership in disaster recovery planning and IAVA compliance empowers engineers and developers to securely deliver operations, ultimately protecting the integrity and availability of our technological infrastructure.

Work hours are 9am – 5pm, Monday thru Friday.
