About The Position

CHAOS Industries is seeking a Senior Staff Antenna Engineer to design, analyze, and test antennas and RF front ends for radar, electronic warfare, and sensing systems. The engineer will own assigned antenna development efforts from architecture trades through qualification and production, collaborating with RF, digital, mechanical, and thermal engineers to resolve technical challenges. This is a hands-on individual contributor role in a fast-moving engineering environment. The engineer will provide antenna technical guidance to teammates, and their designs will reach the field. This is a full-time, on-site position in El Segundo, California. U.S. citizenship is required, and candidates must be able to obtain and maintain a U.S. security clearance; an active clearance is preferred. The stated base salary range is $237,000–$264,000, excluding bonus, equity, and benefits. Compensation may vary based on factors including work experience, education, training, skills, and business considerations.

Requirements

Bachelor’s degree in Electrical Engineering, Physics, or a related field.
10 or more years of antenna engineering experience in radar, EW, or related RF sensing applications.
Deep expertise in antenna design in at least one frequency band, with working knowledge of antenna design across other frequency bands.
Experience designing phased arrays and RF front ends, including element design, scan performance, mutual coupling, sidelobe control, polarization, calibration, and beamforming.
Experience with narrowband and wideband architectures such as TCDA, Vivaldi, or log-periodic design.
Hands-on experience with electromagnetic simulation, antenna measurement, and model-to-test correlation.
Experience integrating antennas with beamforming electronics, radomes, structures, and thermal systems.
Ability to work independently on assigned technical efforts and collaborate effectively across disciplines.
U.S. citizenship.
Ability to obtain and maintain a U.S. security clearance.

Nice To Haves

Master’s degree in Electrical Engineering, Applied Physics, or a related field.
Experience with digital or adaptive beamforming, monopulse processing, multifunction arrays, or conformal arrays.
Experience with ruggedized antennas, radomes, and installed-antenna performance.
Experience with design for manufacturing, automated calibration, and production test.
Technical contributions demonstrated through fielded systems or patents.
An active U.S. security clearance.

Responsibilities

Perform architecture and design trades and select antenna approaches based on mission performance, SWaP-C, reliability, producibility, and cost.
Translate system requirements into antenna, aperture, RF front-end, and radome requirements.
Design, analyze, integrate, and test antennas and phased arrays for active and passive RF systems, including wideband and narrowband architectures.
Lead antenna and RF front-end development for AESA systems, from architecture through integration and qualification.
Perform electromagnetic modeling and array analysis using tools such as HFSS, CST, MATLAB, and Python, including custom analysis scripts.
Plan and conduct antenna verification and qualification, and correlate analytical predictions with measured performance.
Build and integrate antenna prototypes, support test campaigns, and participate in field integration and support.
Work directly with thermal, mechanical, RF, and digital engineers to deliver integrated, producible designs.
Provide antenna technical guidance during design reviews, integration discussions, and requirements development.
Identify technical risks and resolve them or escalate them as appropriate, engaging outside specialists when needed.
Contribute to antenna design methods, analysis tools, and test approaches as the team matures.
Contribute to sponsored research and university partnerships that advance antenna technologies and develop technical talent.
