(RII) is breaking through the big, slow status quo with transformative technology that fundamentally improves the world. We build advanced software solutions for government and military missions, applying agile development and user-centered design to solve complex, mission-critical problems. Dragonfly is RII's next-generation electromagnetic spectrum operations platform, combining advanced sensor integration, GPU-accelerated signal processing, artificial intelligence, and autonomous spectrum operations to deliver real-time spectrum awareness, passive target detection, electronic warfare support, and mission-focused analytics across man-portable, vehicle-mounted, maritime, and airborne environments. We are seeking a Software Development Engineer in Test (SDET) to ensure the quality, reliability, and operational readiness of Dragonfly's software across its full mission capability set. In this role, you will design and execute test strategies spanning controlled lab environments and live outdoor RF collection scenarios, validating everything from core signal processing pipelines and direction finding accuracy to partner system integrations and the browser-based tactical UI. You will work closely with software engineers, systems integrators, and program teams to define acceptance criteria, build automated test frameworks, and drive defects to resolution. The ideal candidate brings a strong software testing foundation combined with a genuine interest in RF systems, electronic warfare, or defense technologies, and thrives in a hands-on environment where the lab is just as likely to be a parking lot with an antenna as it is a bench in an office.
