Role Overview:
CHAOS is seeking a Senior Staff Antenna Engineer to design, analyze, and test antennas and RF front ends for radar, electronic warfare, and sensing systems. You will own assigned antenna development efforts from architecture trades through qualification and production, working closely with RF, digital, mechanical, and thermal engineers to resolve challenges.
This is a hands-on individual contributor role in a fast-moving engineering environment. You will provide antenna technical guidance to teammates, and your designs will reach the field.
This is a full-time, on-site position in El Segundo, CA.
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
Minimum Requirements:
•
Bachelor’s degree in Electrical Engineering, Physics, or a related field, and 10+ years of antenna engineering experience in radar, EW, or related RF sensing applications
