At RTX, the world's largest aerospace and defense company, 185,000 great minds are united by purpose and inspired to make a difference solving the world's most complex problems. With our three market leading businesses, world-class operations and investments in research and development, we offer capabilities and opportunity no one else can. Together, we push the boundaries of known science and find new ways to connect and protect our world.

Collins Aerospace is a leader in technologically advanced, intelligent solutions that help redefine the aerospace and defense industry. With a comprehensive portfolio and deep technical expertise, we help customers meet the demands of the global market. Join us and help shape the future of aerospace and defense.

The Collins Test Solutions Engineering team within Mission Systems seeks a Software Engineer with the desire to learn, grow, and lead a talented team of engineers. The Software Engineer engages in all phases of a program life cycle, from pursuit, bidding, and program planning, to execution, delivery, and project close-out. Throughout a program, the Software Engineer performs the roles of customer and/or engineering advocate, internal/external point of contact, technical leader, cost account manager, schedule planner, risk and opportunity facilitator, and program reporter.

Our Test Engineering team designs, builds, and deploys sophisticated testing solutions for product engineering, manufacturing, and repair depots, both internal to Collins and to external domestic and international customers. We work with a vast array of complex products so designing a multi-rack test solution blends creativity with technology to ensure end-product integrity before customer delivery. Testing these products can require leading edge equipment with high-speed connectivity for rapid, efficient, complete, and automated test execution. Every type of engineering that goes into end products applies to test engineering development.

What You Will Do:

• Design, create, and integrate the software components of hardware test stations for factory and engineering labs which include:
• Work hands on, with test hardware equipment to develop software which tests military communication hardware products during the build and manufacturing process
• Analyze and understand requirements to ensure testability
• Develop clear and concise test objectives that guide the testing process and ensure comprehensive coverage
• Write software for both manual and automated test cases, with an objective to detect manufacturing defects, improve product quality and increase manufacturing yields
• Analyze test results for failures and discrepancies
• Work closely with other test engineers and product developers to verify product hardware is built correctly
• Coordinate and collaborate with Systems, Electrical and Mechanical engineering disciplines

Qualifications You Must Have:

• Active and transferable Secret U.S. government issued security clearance is required prior to start date.
• Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 5 years prior relevant experience or an Advanced Degree in a related field and minimum 3 years of experience
• Experience programming in C# and Python languages
• Experience in validation, verification, testing, and requirements analysis
• Experience with manual use or automation of test equipment such as oscilloscopes, network analyzers, and other equipment

Qualifications We Prefer:
