About the work:
In May of 2019, Amazon opened its first AWS Ground Station, a "virtualized segment for ground processing" of satellite signals that support 54 MHz uplink and 500 MHz downlink processing using the proven AWS Cloud Services and technologies. Microsoft Orbital and Google were close behind with their own satellite processing architectures based on cloud services and technologies. At the same time, technologies supporting next-generation 5G exploded into the same cloud technology arena. Geon has been awarded a prime contract to leverage these very same technologies to build next-generation Software Defined Radio (SDR) solutions for the defense and intelligence industry. We are looking for fully-cleared individuals that have an ambition to leverage their proven experience in building high performance processing systems and solutions to architect, develop, productize and deploy a whole new breed of open-sensor framework based on the industries leading solutions. If you are interested in working with and learning the newest technologies, and continue to support our nations intelligence and defense priorities, contact Geon immediately to secure a highly competitive position on our team.
