Senior Software Defined Radio (SDR) Engineer

Description

Summary: This role involves designing, developing, and integrating high-performance Software Defined Radio (SDR) solutions within the Electronic Warfare Division. Highlights: 1. Design and deploy advanced SDR systems using Ettus Research USRP hardware 2. Develop high-performance SDR applications in C++ and Python 3. Perform RF system integration, testing, calibration, and troubleshooting Apply Now Description Today, Electronic Warfare (EW) is a growing enterprise — protecting the warfighter and our nional security against ever-adapting thres. Our division currently has an exciting opportunity for a Software Defined Radio (SDR) Engineer to perform design, development, and hardware/software integrion in Arlington, VA for the Electronic Warfare Division. Our division primarily focuses on research & development and advanced prototyping, transforming ste-of-the-art signal processing algorithms into real-time software systems deployed on advanced RF plforms. The successful candide will be an individual contributor responsible for designing, developing, and integring high-performance SDR solutions using Ettus Research USRP plforms. This role requires expertise in real-time RF signal processing, low-lency streaming architectures, and software development close to the hardware layer. The ideal candide is comfortable building production-grade SDR systems from the ground up and optimizing them for demanding operional environments.
