About The Position

Athenix Special Missions is seeking a Data Protection Engineer (Trellix), Zero Trust Program (USSOCOM) in MacDill Air Force Base (Tampa), Florida!

Must be a U.S. Citizen
Security Clearance: Active Top-Secret clearance

We are seeking a specialized Data Protection Engineer (Trellix) to join the SIPR and Top-Secret Network Execution Teams for a major Zero Trust transformation at U.S. Special Operations Command (USSOCOM). While other roles focus on cloud-native security, this position is dedicated to securing the "tactical edge" and on-premises endpoints within the Command's classified environments.

As the Senior Trellix Engineer, you will be the technical authority for the design, deployment, and management of the Trellix (formerly McAfee) Data Loss Prevention (DLP) suite. You will be responsible for configuring and tuning the Trellix ePolicy Orchestrator (ePO) to enforce rigorous device control and data protection policies on workstations operating in disconnected and air-gapped environments. Your work will directly prevent the unauthorized exfiltration of classified intelligence via USB drives, printing, and clipboard transfer, ensuring that the Command’s most sensitive networks remain secure against insider threats and accidental data loss.
