Senior Antenna Design Engineer

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.

• 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.
