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 Advanced Effectors Guidance Systems department is seeking a Sr Principal Radar / RF-focused Electrical Subsystems Engineer with deep experience in RF subsystem design, radar development, and RF seeker integration. This role emphasizes the architecture, modeling, design, and integration of advanced radar-based guidance subsystems and supporting RF front-end and back-end components. You will drive subsystem requirements, conduct performance modeling, and decompose radar and RF functional needs into implementable hardware architectures.

What You Will Do

• Develop and architect radar and RF subsystem solutions, including front-end RF chains, antennas, high-speed digitizing paths, and signal-processing-critical interfaces.

• Perform modeling, analysis, and simulation of RF and radar subsystem performance, including ultra-wideband (UWB) and high-power-density architectures.

• Evaluate hardware designs, subsystems, and components for radar seekers and related RF systems.

• Generate and document subsystem-level requirements, interface definitions, test plans, and verification artifacts.

• Conduct technical peer reviews and serve as subject matter expert for radar/RF integration topics.

• Support lab testing, field test events, and root-cause failure analysis for radar and RF subsystems.

• Mentor junior engineers and contribute to technical excellence across the organization.

• Collaborate regularly with program leadership, functional management, suppliers, and customers.

• May support multiple programs simultaneously and travel domestically and internationally as required.

• Build and leverage cross-functional networks to solve complex technical challenges.

Qualifications You Must Have

• Typically requires a Bachelor’s degree in Science, Technology, Engineering, Mathematics (STEM) and 10 years of prior relevant experience (advanced degrees substitute per policy).

• Experience with electrical hardware development.

• Experience in developing RF electrical subsystems, radar hardware, or RF seeker architectures.

• Experience in subsystem or systems engineering, requirement development, and validation.

• RF Modeling experience in HFSS and/or CST.

• Experience with high-power-density RF architectures and thermal/electrical trade-space management.

• Experience with high-speed digitizing and high-bandwidth memory systems.

Qualifications We Prefer

• Hands-on experience with missile radar or RF seeker subsystems.

• Background in detailed design, troubleshooting, and integration of radar/RF components.

• Experience or knowledge of adaptive radar resolution-improvement techniques.

• Deep understanding of S-parameters and impedance-matching techniques.

• Experience with systems engineering and architecture.

• Experience working with missile systems or high-reliability products.

• Knowledge of mixed-signal electronics.

• Familiarity with ultra-wide-bandwidth microwave components and design approaches.

• Ability to manage cross-functional teams and drive suppliers.

• Strong understanding of thermal, electrical, and microwave physics dependencies.

• Knowledge of DoD/DoW hardware development processes.

• Experience with Model-Based Systems Engineering (MBSE).
