Are you ready to explore the world of aerospace and defense? Do you want to learn from and collaborate with some of the greatest minds in the industry? At RTX, our internships, co‑ops and full‑time careers provide an exceptional foundation to work on complex problems, advance your skills and create a safer, more connected world. Discover opportunities to make a difference at RTX.

The Test Equipment Engineering (TEE) organization includes all of the engineering disciplines responsible for systems design & test of all Raytheon products. Our engineers are responsible for all elements of the development lifecycle for test including: test requirements, test system design, advanced engineering prototyping technology, flight operations, environmental testing, and environmental characterization. We are hands‑on, designing with the latest technology and tools, and integrate state of the art test solutions with the most advanced engineering systems in the world.

As a Test Systems Engineer II, you will work with multiple engineering teams to define, design, and document Test Environment capabilities and requirements. You must be a systems thinker, able to see the “big picture”, and be open to growth to understand how prime hardware should be tested at every (from component to All‑Up‑Round) to ensure robustness and efficiency.

What You Will Do

• You will apply your knowledge of the subsystem and collaborate with other Engineering disciplines to develop and implement the subsystem model using Model Based System Engineering tools and methods.

• Detail capabilities and derive requirements.

• Communicate test equipment needs and requirements to Test Equipment designers.

• Manage requirements and traceability.

• Leverage and apply reuse of Test Environment requirements and models to promote efficiency in test design and development.

• You will develop subsystem requirements, interfaces, behaviors, and architecture.

• You will interact with Technical SMEs as necessary to fully understand the subsystem including identifying and resolving issues and supporting related subsystem trades or analysis.

Qualifications You Must Have

• Master’s in Science, Technology, Engineering, or Mathematics (STEM)

• Systems Engineering experience in test requirements development, test planning, test techniques, test methodologies, embedded functional test, and integration, verification, and validation for test
