Scenario Thread Development — Support development of mission and operational scenario threads to inform system design and performance requirements.
Digital Engineering Integration — Apply MBSE and Digital Engineering best practices to define the to‑be system design, including mission, cyber, interoperability, and environmental requirements.
Lifecycle Engineering Support — Contribute to system baseline development across the program’s three-phase contract: requirements definition, baseline establishment, and deployment of the modernized solution.
Bachelor’s degree in Systems Engineering, Information Systems, Computer Science, or related field and 8+ years of relevant experience (additional experience, training, or certifications may substitute for degree).

Demonstrated experience with Model-Based Systems Engineering (MBSE), Digital Engineering, Cameo, scenario thread development, system integration, configuration management, cybersecurity, test support, and CI/CD.
Strong written and verbal communication skills with the ability to engage both technical and non‑technical stakeholders.
Master’s degree in a related field with 6+ years of relevant experience.
Professional certifications such as DoD IAT Level II (e.g., Security+).
Experience supporting DoD, MDA, U.S. Space Force, Air Force, or Intelligence Community programs.
Experience with Integrated Tactical Warning / Attack Assessment (ITW/AA) systems or radar systems.
Experience with missile and space on‑orbit events, cybersecurity, classified networks, cloud solutions, operational acceptance governance, and system lifecycle management.
