Date Posted: 2026-05-07 Country: United States of America Location: US-TX-MCKINNEY-513WD ~ 2501 W University Dr ~ WING D BLDG Position Role Type: Onsite U.S. Citizen, U.S. Person, or Immigration Status Requirements: The ability to obtain and maintain a U.S. government issued security clearance is required.​ U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance Security Clearance Type: DoD Clearance: Secret Security Clearance Status: Active and existing security clearance required after day 1 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. Our Airborne Antennas, Radome & Apertures team is recognized across the defense community as one of the most capable antenna and low observable (LO) engineering groups in the United States. Our engineers tackle some of the world’s toughest RF, antenna, and aperture challenges. We design high performance, highly integrated, mission critical antennas, radomes, and active electronically scanned arrays (AESAs). We are seeking an Antenna Design Engineer II to support the development of advanced LO antennas and ultra‑wideband phased arrays. This role is ideal for new M.S. EE graduates who want to work on programs of national importance and who excel in both deep technical analysis and hands‑on engineering. This position requires job duties to be performed onsite due to the sensitive nature of this work and the desire for in-person collaboration; however, we offer flexible in-office hours and the ability to perform some job duties remotely. What You Will Do Provide technical solutions to a wide range of challenging problems involving antenna and AESA based applications such as radar, electronic warfare, communications, and direction finding. Use advanced computational electromagnetic (CEM) software (HFSS, CST, FEKO, SENTRi) to design, model, and predict performance of antennas and apertures including spiral, sinuous, Vivaldi, patch, slot, horn, and ultra‑wideband tightly coupled dipole arrays (TCDA). Create, refine, and optimize antenna designs using full‑wave solvers, run parametric studies, and balance electrical, mechanical, LO, and environmental constraints. Perform EM simulation and/or test to verify compliance with antenna‑level and system‑level requirements, performing root‑cause investigations when issues arise. Participate in testing of RF hardware for key performance metrics such as VSWR, insertion loss, gain, efficiency, polarization, and radar cross section (RCS). Support antenna prototyping, build reviews, troubleshooting, and integration activities in collaboration with Operations, Manufacturing, and Test Engineering. Contribute to internal and customer‑funded research and development programs involving antenna, phased‑array, or RF component/system design. Document technical approaches, design decisions, and verification results in engineering reports and formal design reviews. Travel Requirements: Less than 10% annually. This 1st shift role will be 100% on-site and based in McKinney, TX. Qualifications You Must Have Typically requires a Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM) and minimum of two (2) years of relevant RF engineering experience including any combination of the following: Design, fabrication, and / or testing of conformal antennas, apertures, and passive RF components such as radiating elements, radomes, power dividers, couplers, RF transitions, multilayer boards, and / or Frequency Selective Surfaces (FSS). Experience designing and / or testing ultra wideband phased array antennas such as Tightly Coupled Dipole Arrays (TCDA), Vivaldi, Sliced Notch, and / or Planar Ultra Wideband Modular Arrays (PUMA). Experience with the use of EM modeling tools such as HFSS, CST, FEKO, or SENTRi. Experience performing testing using RF equipment including VNAs and far-field antenna ranges. Qualifications We Prefer Master’s or PhD in Electrical Engineering with a concentration in RF/Microwave circuits. 3.5+ cumulative GPA. Electromagnetic modeling and simulation experience with conformal antennas or airborne apertures. Knowledge of printed wiring board (PWB) or printed circuit board (PCB) fabrication processes, stack‑up design, and design rules. Strong written and verbal communication skills supported by publications, technical presentations, or student awards. Ability to troubleshoot complex antenna or RF performance issues and collaborate across multidisciplinary teams. Experience supporting prototype builds, test automation, fixture design, or specialized antenna range measurements. Why Join Raytheon’s Airborne Antenna Radomes and Apertures Team Work on antennas that go onto real platforms and deliver real‑world mission impact. Access to one of the broadest ranges of antenna technologies in industry (AESA, UWB, LO, conformal, EW, comms, radar, sensing). Deep technical career growth supported by nationally recognized experts. Collaborative environment with multidisciplinary engineering excellence.
