## Description

As a Systems Engineer within TSE, you will collaborate with cross-functional engineering teams to design, model, integrate, and validate subsystem-level test solutions that support all phases of the product lifecycle, including early demonstrations, engineering tests, design verification, production, and sustainment. This is a hands-on role involving Model-Based Systems Engineering (MBSE), requirements development, test architecture, problem-solving, and coordination with technical subject matter experts., * Develop and implement subsystem models using Model-Based Systems Engineering tools and methods.

 * Collaborate with multidisciplinary teams to define capabilities, derive requirements, and establish interfaces, behaviors, and architecture.

 * Communicate test equipment needs, requirements, and constraints to Test Equipment designers.

 * Manage and maintain requirements and traceability throughout the product lifecycle.

 * Leverage reusable models, architectures, and test environment requirements to improve development efficiency.

 * Support integration, verification, and validation activities for both hardware and software-based test systems.

 * Interact with SMEs to fully understand system behaviors, resolve issues, and support engineering trade studies.

 * Participate in design reviews, technical discussions, and cross-functional coordination.

 * Support problem-solving, debugging, and continuous improvement efforts.

 * (As experience increases) Mentor junior engineers and contribute to team development.
