The Senior Systems Engineer will design, architect, and integrate complex DoD software systems, lead test execution efforts in the field, interface directly with senior warfighters and government sponsors, and drive resolution of complex integration and operational issues during test events. This role is hands-on and requires strong judgment, adaptability, and technical leadership in high-visibility environments.
