Job description

U.S. Citizenship and an active DoD Secret clearance are required prior to start date. This onsite position is located at 1151 E Hermans Rd, Tucson, AZ (Building M02).

Advanced Effector Guidance Systems Department

The department provides Electrical Systems Engineering to develop electronic systems solutions across the Raytheon portfolio, focusing on RF/RADAR, Navigation/IMU/GPS, Data Link/Communication, Digital, and Power technologies. It partners with several Electrical Product Team departments for detailed design and with systems teams.

Principal Radar / RF-focused Electrical Subsystems Engineer

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 a minimum of 8 years of prior relevant experience
• 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 Value

• Familiarity with ultra-wide-bandwidth microwave components and design approaches.
• Experience or knowledge of adaptive radar resolution-improvement techniques. Deep understanding of S-parameters and impedance-matching techniques.
• Strong understanding of thermal, electrical, and microwave physics dependencies.
• Hands-on experience with missile radar or RF seeker subsystems.
• Background in detailed design, troubleshooting, and integration of radar/RF components.
• Experience with systems engineering and architecture.
• Experience working with missile systems or high-reliability products.
• Knowledge of mixed-signal electronics.
• Ability to manage cross-functional teams and drive suppliers.
• Knowledge of DoD/DoW hardware development processes.
• Experience with Model-Based Systems Engineering (MBSE).

What We Offer

Our values drive our actions, behaviors, and performance with a vision for a safer, more connected world. 100% onsite in Tucson, AZ, and eligibility for relocation assistance.

Salary and Benefits

Salary range: 107,500 USD - 204,500 USD. Hired applicants may be eligible for benefits including medical, dental, vision, life insurance, short-term disability, long-term disability, 401(k) match, flexible spending accounts, flexible work schedules, employee assistance program, Employee Scholar Program, parental leave, paid time off, and holidays.
