Responsibilities focus on architecture, modeling, design and integration of advanced radar-based guidance subsystems and supporting RF front‑end and back‑end components.

• 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.

• 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.
• 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).

• Relocation assistance for the Tucson, AZ location.
• Health, dental, vision, life insurance, and short‑term disability coverage.
• Long‑term disability, 401(k) match, flexible spending accounts, flexible work schedules.
