Role Overview:
CHAOS is seeking an early-career Antenna Engineer to contribute to the design, analysis, and testing of antennas and RF front ends for radar, electronic warfare, and sensing systems. You will work with experienced engineers on antenna development from architecture trades through prototype build, integration, qualification, and production.
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
Understanding of antenna theory, electromagnetic propagation, polarization, and antenna measurement
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
