We deliver solutions that help our nation and allies defend freedoms and deter aggression, creating a safer, more secure world. Join us and help shape the future of aerospace and defense.

Join Systems Engineering and Test Capabilities (SE&TC), a cross-disciplinary engineering team solving complex systems challenges across some of Raytheon’s most advanced guided, autonomous and sensor‑integrated technologies. If you’ve engineered complex vehicles, robotics platforms, automated machinery, aerospace systems or embedded technologies, many of the systems engineering skills you’ve developed can translate directly to this work. Based in Tucson, Arizona, SE&TC supports technologies spanning the seabed to space, including ship‑launched systems such as Standard Missile® and Tomahawk®, surface‑launched systems including Javelin® and Coyote®, air‑launched systems such as AMRAAM® and Storm Breaker®, and emerging technologies including hypersonics and space solutions.

As a Systems Engineer, you’ll apply that experience across the full Systems Engineering V lifecycle, shaping architecture, requirements, integration and verification for complex systems that must perform reliably under demanding conditions. You’ll collaborate across software, hardware, modeling, controls, navigation, sensors and test to bring these systems from concept through field performance. This role is 100% on‑site at our Tucson, AZ campus with the possibility of occasional travel.
