About The Position

Tetrad Digital Integrity (TDI) is a leading-edge cybersecurity firm with a mission to safeguard and protect our customers from increasing threats and vulnerabilities in this digital age. TDI is seeking Risk Management Framework (RMF) subject matter experts as Information Systems Security Managers to support cloud-based and Artificial Intelligence (AI) integrated systems. We are looking for candidates who have demonstrated experience building and maintaining RMF packages from development and through sustainment, are technically sharp, and ready to work in a fast-paced environment on some of the nations most advanced systems.
