Senior Antenna Design Engineer

RTX•McKinney, TX

4d•$86,800 - $165,200•Onsite

About The Position

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 a Senior Antenna Design Engineer to drive the development of advanced antennas, ultra‑wideband phased arrays, and next‑generation LO survivability technologies for demanding systems. This role is ideal for senior engineers who want to work on programs with national‑level importance and who excel at 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.

Requirements

Typically requires a Bachelor’s in Science, Technology, Engineering, or Mathematics (STEM) and minimum of five (5) years of relevant RF engineering experience including any combination of the following:
Radar Cross Section (RCS) modeling, prediction, measurement, or reduction
Design antennas, phased array apertures, or RF passive components (radiators, radomes, couplers, transitions, multi‑layer RF structures, FSS)
Ultra‑wideband phased array development (TCDA, Vivaldi, Sliced‑Notch, PUMA, or similar).
Experience with EM modeling tools such as HFSS, CST, FEKO, SENTRi, X‑Patch, or related CEM software.
Active and transferable U.S. government issued security clearance is required prior to start date.
U.S. citizenship is required, as only U.S. citizens are eligible for a security clearance
DoD Clearance: Secret
Active and existing security clearance required on day 1

Nice To Haves

Master’s or PhD in Electrical Engineering with a concentration in electromagnetics, antennas, survivability, or microwave engineering.
Experience leading contract R&D (CRAD) or advanced development programs.
Familiarity with structural, thermal, materials, or coatings relevant to LO apertures.

Responsibilities

Perform design, modeling, realization, and verification of advanced Low Observable antennas, conformal apertures, ultra‑wideband phased arrays, and passive RF structures.
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.
Lead design teams through architecture trades, detailed EM analysis, LO strategy development, and integration of antenna, RCS, structural, and thermal requirements.
Use full‑wave computational EM tools (HFSS, CST, FEKO, SENTRi, X‑Patch or equivalent) to model antenna performance, RCS signatures, aperture interactions, and airframe‑coupled electromagnetic effects.
Develop and refine antenna and LO design concepts considering gain, VSWR, bandwidth, field of view, scan performance, polarization purity, structural constraints, and signature objectives.
Guide the verification and validation of antenna and RF performance, including gain/pattern testing, polarization, insertion loss, and RCS measurement campaigns.
Work hands on with Operations, Assembly, and Test personnel to fabricate prototypes, debug hardware, optimize builds, and support manufacturing and qualification.
Present complex technical findings to internal leadership and program stakeholders with clarity and authority.
Execute tasks requiring creativity, innovation, and independent technical judgment on high‑visibility programs.
