Raytheon’s Radome & Apertures team seeks a Principal Antenna Design Engineer to advance ultra‑wideband phased array antennas, individual antennas, and RF Low Observables (LO). The role supports interdisciplinary teams in AESA, CEM, RF test, mechanical, structural, thermal, material science, and survivable antenna technology. The engineer will perform both theoretical design and hands‑on engineering tasks, collaborate across functions, and mentor junior staff.

• Hands‑on design and realization of LO antennas, phased array antennas, and passive RF components.
• Use computational electromagnetic analysis software to design and predict performance on various antenna and aperture types.
• Support customer programs through modeling and simulation of LO antennas or RF components/systems and lead teams performing these functions.
• Provide technical solutions to a wide range of difficult problems involving antenna/sensor‑based applications such as radar, electronic warfare, electronic attack, electronic support measures, communications, geolocation, direction finding, etc.
• Establish and maintain effective working relationships with internal and external customers.
• Mentor and guide more junior engineers and technicians in design, build, and test phases of projects and programs.
• Work with interdisciplinary engineering teams including thermal, structural, mechanical, and systems.
• Participate in and guide the testing of RF hardware for required performance metrics: VSWR, insertion loss, gain, polarization, RCS.
• 1st shift – 100% on‑site, based in McKinney, TX.

• Degree in STEM (e.g., Electrical Engineering) and minimum 8 years of prior work experience, or Advanced Degree with minimum 5 years’ experience.
• Engineering experience in:
  • RCS reduction, prediction, measurement, and analysis & simulation.
  • Design, fabrication, and test of conformal antennas, apertures, and passive RF components.
  • Designing, fabricating, and testing ultra‑wideband phased array antennas such as Tightly Coupled Dipole Arrays, Vivaldi, Sliced Notch, Planar Ultra‑wideband Modular Arrays.
• Experience with RCS analysis tools such as X‑Patch, SENTRi, FEKO, HFSS, CST, or other CEM analysis packages.
• Active, transferable U.S. government‑issued security clearance is required prior to start date. U.S. citizenship is required.

• Master’s or PhD in Electrical Engineering with a concentration in Electromagnetics.
• Experience presenting technical data to peers, executives, and customers.
• Experience writing and leading technical proposals.
• Experience winning new business and executing contract research and development (CRAD) programs.

• Relocation based on candidate eligibility.
• Benefits include medical, dental, vision, life insurance, short‑term disability, long‑term disability, 401(k) match, flexible spending accounts, employee assistance program, parental leave, paid time off, and holidays.
