We are seeking an
Antenna Design Engineer II to support the development of advanced 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.
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, or testing of antennas, apertures, and passive RF components such as radiating elements, radomes, power dividers, couplers, RF transitions, multilayer boards, or Frequency Selective Surfaces (FSS).
- Experience designing and testing ultra wideband phased array antennas such as Tightly Coupled Dipole Arrays (TCDA), Vivaldi, Sliced Notch, or Planar Ultra Wideband Modular Arrays (PUMA).
- Experience with EM modeling tools such as HFSS, CST, FEKO, or SENTRi.
Qualifications We Prefer- Master's or PhD in Electrical Engineering with a concentration in RF/Microwave circuits.
- 3.5+ cumulative GPA.
- Electromagnetic modeling, simulation and test experience with phased array antennas or wideband antennas.
- 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.
