Senior Model Based Systems Engineer

MTSI is seeking a Senior Model-Based Systems Engineering (MBSE) Architect to serve as a technical leader supporting mission engineering, digital transformation, and enterprise architecture development for defense customers.

In this role, you will lead complex system-of-systems architecture efforts, guide teams of engineers, and drive the development and implementation of digital engineering ecosystems.

You will construct and analyze enterprise-level architectures and kill‑web/effects‑web constructs, support mission engineering studies, develop digital workflows, and ensure high‑quality technical deliverables across government programs.

This position requires deep experience in MBSE methodologies, SysML/UAF/DoDAF modeling, mission thread development, complex systems analysis, and coordination with senior defense stakeholders.

• Lead medium‑to‑large technical engineering efforts applying advanced analytical and systems engineering principles to mission‑critical challenges.
• Identify technical approaches, plan system architecture development, and assign engineering resources to execute MBSE solutions.
• Provide senior-level technical leadership ensuring alignment of digital engineering products to customer requirements and program objectives.
• Develop, update, and maintain enterprise‑scale MBSE architectures including mission threads, METs/MTs, kill chains, and kill-web/effects-web models.
• Lead the creation of system CONOPS, requirements documents, preliminary design reviews, segment-level specification reviews, and technical deliverables.
• Drive adoption of digital engineering tools, environments, and hybrid cloud ecosystems to support mission engineering activities at scale.
• Support mission engineering analyses by integrating modeling and simulation tools and digital artifacts into a unified environment (e.g., AFSIM).
• Mentor junior and mid‑level MBSE practitioners, providing technical direction, trade study leadership, and methodological guidance.
• Coordinate directly with senior government stakeholders, Joint Staff, Service Components, and Mission Integration teams to align engineering outputs with operational needs.
