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.

• A bachelor’s degree in science, Technology, Engineering, or Mathematics (STEM) and 2-10+ years of relevant engineering experience (higher experience levels also acceptable; equivalent master’s degree combinations recognized).

• Systems Engineering experience involving test requirements development, test planning, test methodologies, embedded functional test, integration, verification, and validation.

• Experience developing and managing system requirements across the engineering lifecycle.

• Experience with Model-Based Engineering tools and languages such as:

• Rhapsody, IBM Rational Model Manager

• Cameo Systems Modeler / Enterprise Architect

• Teamwork Cloud

• SysML and/or UML

• Experience with test-related activities across design, production, or sustainment environments.

• Ability to obtain and maintain a U.S. security clearance prior to start; U.S. citizenship required.

Preferred Qualifications:

• Experience with Agile development processes and tools.

• Experience with DOORS or other requirements management tools.

• Experience in development, environmental testing, qualification testing, production, or manufacturing test environments.

• Experience with design-for-test, embedded test techniques, and margin analysis.

• Strong troubleshooting and debugging skills.

• Ability to identify process improvements or customer needs and communicate them effectively.

• Experience leading or mentoring engineers (for higher levels).

• Experience with EVMS, program planning, EAC development, or cross-functional task coordination (plus for senior candidates).

• Demonstrated adaptability, urgency, risk-informed decision making, and strong communication skills.
