At Raytheon, the foundation of everything we do is rooted in our values and a higher calling – to help our nation and allies defend freedoms and deter aggression. We bring the strength of more than 100 years of experience and renowned engineering expertise to meet the needs of today's mission and stay ahead of tomorrow's threat. Our team solves tough, meaningful problems that create a safer, more secure world.

The Advanced Effector Guidance Systems Team provides Electrical Systems Engineering to develop Guidance Electronics solutions for products across the Raytheon portfolio. We partner with several Electrical Product Team departments that provide the detailed design of our electrical products as well as missile level systems teams. Our core electrical engineering responsibilities include architecture, requirements, integration, and test, utilizing technologies such as RF/RADAR, Navigation/IMU/GPS, Digital, and Power.

About the Role

The Advanced Effector Guidance Systems Team is searching for a Principal Subsystem Engineer with experience as an Integrated Product Team Lead (IPTL).
