Engineering & Design

Amentum provides full-lifecycle engineering and design across civil, mechanical, electrical, structural, and systems disciplines. Our engineers support facility design and construction, systems integration, technical baseline development, and engineering change management for defense, government, and commercial clients. We apply model-based systems engineering (MBSE) and digital engineering tools to improve design quality, reduce rework, and accelerate delivery. From initial concept development through detailed design, construction oversight, and commissioning, Amentum’s engineers bring technical excellence and mission focus to every project.
