Freelance Integration Software Engineer Jobs in Virginia

Everforth ECS is seeking a Junior Software Engineer to work in the National Capital Region covering the Pentagon, Falls Church, and Fairfax. Please Note: This position is contingent upon contract award.
The War Data Platform (WDP) is a key initiative within the U.S. Department of War's (DoW) AI-First strategy introduced in early 2026. The WDP separates business and financial data from operational warfighting data, aiming to accelerate the deployment of artificial intelligence (AI) on the battlefield. The WDP extends to Unclassified, Secret, and Top Secret environments, and supports collaboration between Combatant Commands, Joint Staff directorates, Senior Executive Service leaders, and operational analysts.
The Junior Software Engineer contributes to WDP Core Integration software development by implementing assigned features, fixes, and configuration updates across development, test, integration, and staging environments spanning NIPRNet, SIPRNet, and JWICS under the guidance of senior software engineers. This is an entry-level role offering meaningful hands-on exposure to full-lifecycle, mission-critical government software engineering within a high-tempo DevSecOps delivery environment where code quality and security compliance directly impact warfighter outcomes.
