Job summary

RTX in Tucson, AZ is seeking a Principal Radar / RF-focused Electrical Subsystems Engineer to lead the architecture, modeling, design, and integration of advanced radar-based guidance subsystems and RF front-end/back-end components. You will drive subsystem requirements, perform performance modeling, and collaborate with program leadership, suppliers, and customers; travel domestically and internationally as required.

This onsite role requires U.S.

Qualifications

• Requires a Bachelor’s degree in STEM and 8+ years of relevant experience.
• Experience developing RF electrical subsystems, radar hardware, or RF seeker architectures.
• Experience in subsystem or systems engineering, requirements 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.

Responsibilities

• Develop and architect radar and RF subsystem solutions, including front-end RF chains, antennas, high-speed digitizing paths, and signal-processing interfaces.
• Model, analyze, and simulate RF and radar subsystem performance (including UWB and high-power-density architectures).
• Evaluate hardware designs, subsystems, and components for radar seekers and RF systems.
• Generate and document subsystem requirements, interface definitions, test plans, and verification artifacts.
• Lead design reviews and act as SME for radar/RF integration topics.
• Support lab testing, field tests, and root-cause failure analysis for radar/RF subsystems.
• Mentor junior engineers and collaborate with program leadership, suppliers, and customers.

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.
