Research Engineer III – RF and Systems Engineer

SRI is seeking a Research Engineer III with a strong background in RF and Systems Engineering to contribute to the development, integration, and evaluation of advanced radar, communications, and sensing systems. This role emphasizes RF system architecture, requirements development, system-level design and analysis, hardware/software integration, and hands-on prototype development and testing. This role is onsite in Boulder, CO.

You will work within multidisciplinary teams to develop advanced systems spanning RF hardware, antennas, digital signal processing, embedded computing, software, and firmware. Applications include radar, communications, electronic warfare, remote sensing, quantum sensing, and photonics. The ideal candidate combines strong RF fundamentals with a systems-level perspective and enjoys taking complex technologies from initial concept and requirements through prototype development, field demonstration, and transition.

This role is part of SRI’s Advanced Technology and Systems Division (ATSD), which develops innovative, high-performance technologies across domains including radar and electronic warfare, imaging systems, robotics, quantum sensing, and applied optics
