Job Description:

Leidos has a career opportunity for a Cybersecurity Analyst in Abingdon, MD to support a critical modernization effort of the Advanced Field Artillery Tactical Data System (AFATDS) in order to satisfy the vision of Program Executive Office (PEO) Command Control Communications - Tactical (C3T) and Project Manager Mission Command. The Cybersecurity Analyst will be expected to integrate and collaborate with all technical teams to deliver a fully-functional system.

The AFATDS is a multi-service, automated command, coordination, communication, and computing system that provides automated fire support and coordination to all echelons, from firing unit through theater level, at Army, Marine Corps, Naval Firing Platforms, Navy Command and Amphibious Assault Ships, Air Force Operations Centers, and Joint Command and Control Centers. AFATDS enables the automatic application of the Force Commander’s guidance in the Fires Warfighting Function to plan, execute, and deliver effects at all levels of command within the current and future force. AFATDS can automatically tailor the selection of fire support assets (field artillery, mortars, close air support, naval gunfire, attack helicopters, and offensive electronic warfare assets) based on the Commander’s guidance, thereby enabling maximum effective use of all available fire support assets across the full spectrum of conflict.

This effort is to meet the government’s objective to modernize the underlying AFATDS architecture, redesign the AFATDS front-end to a fully web- and role-based user interface, integrate common services made available through the Army’s Common Operating Environment (COE), and incorporate advanced embedded training technologies to aid in operator-initiated system instruction and refresher training.
