Job Description

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 (AEGS) Department within Raytheon Hardware Engineering provides Electrical Systems Engineering to develop Electronic Systems solutions for products across the Raytheon portfolio. Our core electrical engineering responsibilities include architecture, requirements, integration, and test.

Our core electrical engineering technologies include RF/RADAR, Navigation/IMU/GPS, Data Link/Communication, Digital, and Power. We partner with several Electrical Product Team departments that provide the detailed design of our electrical products as well as systems teams.

The AEGS Department is searching for an Electrical Subsystems Digital Senior Principal Engineer with experience leading a multi-disciplinary system design and integration team. The role of the Principal Engineer will be to lead or support digital design efforts, digital subsystem architecture design or initial integration efforts of development guidance systems.

This role may include Control Account Management (CAM) responsibilities so Earned Value (EV) certification is preferred.
