We are seeking a seasoned security professional to serve as the Classified Information Security Lead at our Arlington campus. This role is responsible for managing and safeguarding classified information at the Secret and Top Secret levels, ensuring institutional and contractual compliance across a broad range of government-sponsored research programs — including environments with non-standard computing requirements.

The engineer will establish and maintain organizational security policies and procedures, ensure compliance across both classified systems and Controlled Unclassified Information (CUI) environments, and collaborate on the design and implementation of cybersecurity measures protecting digital assets and research data.

Unclassified Systems (NIPR)

The position involves coordinating with sponsors to create and manage unclassified DoD enterprise accounts (e.g., A365) and enforcing DoD-level security protocols across applied, transitioned, and classified research activities.

Classified Systems

Responsibilities include installing, operating, maintaining, and troubleshooting classified IT systems and infrastructure; installing and maintaining classified network connections in approved facilities; and coordinating with sponsors to establish and maintain classified user accounts.

Infrastructure Management

As a member of the CIS Operations Team, the engineer will support day-to-day management of Arlington campus infrastructure, including servers, networks, email, and data centers.
