Defense and Space Manufacturing Chantilly, Virginia 201–500 employees Founded 2005 Privately Held

FTS International provides systems engineering, mission operations, and intelligence analysis services to the U.S. federal sector, with deep expertise in satellite and space systems. The tech stack—SysML, MATLAB, Simulink, STK, Python, and PostgreSQL—reflects a modeling and simulation-first approach typical of aerospace systems integrators. Active hiring is engineering-heavy (25 roles) with senior-level concentration (18 senior, 10 mid), and the project mix shows acute focus on satellite resilience, MBSE workflows, and government acquisition support—areas where contract performance monitoring and cross-system integration are persistent friction points.
