Software Defined Radio Engineer

About the Role

We are seeking an experienced SDR Engineer to contribute to the development of advanced

RF sensing, signal intelligence, and Counter-UAS solutions. The role involves designing and

implementing SDR-based systems for signal detection, classification, protocol analysis, and

spectrum monitoring across a wide range of communication technologies.

The ideal candidate possesses strong RF fundamentals, hands-on SDR development

experience, and the ability to independently execute technical tasks from concept to

deployment.

Key Responsibilities

● Design, develop, and optimize SDR-based RF detection and monitoring systems.

● Capture, analyze, classify, and characterize RF signals across multiple frequency

bands.

● Develop signal processing algorithms for detection, identification, and tracking

applications.

● Implement and maintain GNU Radio flowgraphs and custom SDR software

applications.

● Perform protocol analysis and reverse engineering of wireless communication

systems.

● Conduct laboratory and field testing of SDR-based systems.

● Evaluate RF system performance and recommend improvements.

● Work closely with antenna, embedded, AI/ML, and software teams for system

integration.

● Prepare technical documentation, test reports, and design recommendations.

● Support product development activities from prototyping through deployment.
