Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Antenna Design Engineer - **Company:** RTX - **Location:** McKinney, TX, United States - **Experience:** Expert - **Salary:** $86,800.0 - $165,200.0 - **Contract:** Permanent contract - **Skills:** Software Debugging, Verification and Validation (Software), Hfss - **Published:** September 3, 2026 - **Apply:** https://www.clearancejobs.com/jobs/9142539/senior-antenna-design-engineer ## About the Role * 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., * 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. ## Description 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. What You Will Do * 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. * Travel Requirements: Less than 10% annually. ## Related Videos - [Times of (climate) crisis - How and why sustainable software is a must!](https://www.wearedevelopers.com/videos/988-times-of-climate-crisis-how-and-why-sustainable-software-is-a-must) - [Using AI Without Losing Your Skills](https://www.wearedevelopers.com/videos/2045-using-ai-without-losing-your-skills) - [Kettle and Pot or Peas in a Pod?
