Direct experience within the Department of War (formerly the Department of Defense) or its components: combatant commands, services, or defense agencies, including familiarity with DoW network architectures, RMF/ATO processes, and mission-owner requirements at the tactical and enterprise level. A career that spans at least two of these three worlds (IC, DoW, federal civilian) is strongly preferred - this role requires someone who can speak credibly and specifically to each community''s distinct network architectures, compliance regimes, and unwritten norms, not a generalist who has only sold or supported them from the outside.
