## Description

The Senior Systems Engineer - Digital Engineering / MBSE Innovator will play a key role in advancing digital engineering practices across RTX programs. As a Senior Systems Engineer and MBSE subject matter expert, you will take technical ownership of modeling activities, guide program teams in the application of MBSE methods, and help evolve our Digital Engineering Ecosystem. You will lead the development of system models, shape modeling approaches, and ensure model-based artifacts effectively support design, analysis, verification, and program decision-making. You will collaborate across multi-disciplinary engineering teams, influence technical direction, and provide mentorship to early-career engineers. This is an onsite role located in El Segundo, CA or Fullerton, CA.

What You Will Do

 * Lead development of SysML models that capture stakeholder needs, requirements, behavior, architecture, and interfaces.
 * Guide MBSE implementation on programs, ensuring modeling approaches align to systems engineering processes, program objectives, and customer expectations.
 * Use system models to generate specifications, perform trade studies, support interface definition, and assess technical performance.
 * Drive integration of MBSE models into digital threads, linking requirements, design, and analysis across engineering tools and environments.
 * 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.
