Discover opportunities to make a difference at RTX.

The Test Solutions 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.

What You Will Do

As a Systems Engineer, you are accountable to coordinate across all 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 have the in-depth knowledge of development, production, User Operations, and embedded test process and practices. As a Test Systems Engineer, you will define and influence how prime hardware will be tested at every level (from component to All-Up-Round) to ensure robustness and efficiency.

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

• Bachelor's in Science, Technology, Engineering, or Mathematics (STEM) with a minimum of one (1) year of experience directly related engineering experience
