This is a hands-on individual contributor role. You will use your graduate research and engineering skills on hardware, working directly with RF, digital, mechanical, and thermal engineers. The position is suited to a recent master’s or doctoral graduate who wants to see their antenna designs move from concept to product.

This is a full-time, on-site position in El Segundo, CA.

Responsibilities:

  • Support antenna architecture and design trades based on mission performance, SWaP-C, reliability, producibility, and cost
  • Develop and analyze antennas and phased arrays for active and passive RF systems, including wideband and narrowband architectures
  • Contribute to phased-array antenna development, including AESA systems
  • Perform electromagnetic modeling and array analysis using tools such as HFSS, CST, MATLAB, and Python
  • Build and integrate antenna prototypes; support laboratory testing, measurement, and analysis
  • Compare measured antenna performance with simulation and analytical predictions
  • Support antenna verification and qualification activities
  • Work with RF, digital, mechanical, and thermal engineers to resolve integration challenges and deliver producible designs
  • Participate in design reviews, help develop requirements, identify technical risks, and contribute to design decisions
  • Contribute to antenna analysis methods, scripts, and test approaches
  • Support technical work with university and research partners

    • Minimum Requirements:

  • Master’s degree or PhD in Electrical Engineering, Applied Physics, Engineering Physics, or a related field
  • Graduate research, thesis, project, or internship experience involving antenna design, electromagnetics, RF systems, or related topics

  • Familiarity with phased arrays or array analysis through coursework, research, or project work
  • Experience with electromagnetic simulation tools such as HFSS or CST, and analysis tools such as MATLAB or Python
  • Ability to communicate technical work clearly and collaborate across engineering disciplines
  • Ability to obtain and maintain a U.S. security clearance

    • Preferred Requirements:

  • Research or project experience with phased arrays, AESA antennas, or RF front ends
  • Experience with wideband or narrowband antenna architectures, such as Vivaldi, TCDA, or log-periodic designs
  • Experience building antenna prototypes or performing antenna measurements
  • Experience with beamforming, array calibration, mutual coupling, scan performance, or sidelobe analysis
  • Internship or project experience in radar, EW, aerospace, defense, or related RF sensing applications
  • Technical contributions demonstrated through publications, conference presentations, patents, or research awards
