Promote and apply reusable modeling practices, standards, and MBSE starter models to increase consistency and modeling efficiency.
Mentor Systems Engineers and Modelers, sharing best practices and enabling teams to effectively adopt MBSE workflows.
Communicate technical progress, risks, and recommendations to program leadership, presenting model insights to support engineering decisions.

Experience with engineering design or analysis tools used across the product development lifecycle
Familiarity with digital thread concepts, digital twin workflows, and integration of MBSE tools within Digital Engineering environments
