Senior RF Engineer

About the position

Planet is working on the next generation small satellite bus that will host a high resolution optical imaging payload (Pelican) and a hyperspectral payload (Carbon Mapper). Planet has continuously iterated and developed small spacecraft communication systems including board level hardware, antennas, and ground station equipment that produce record data rates. Our system consists of transceivers in several bands, as well as a worldwide network of ground stations. We are seeking an experienced RF and Microwave Engineer to develop our next-generation onboard, ground radios and antenna systems that push the frontiers of satellite communications. You will make evolutionary and revolutionary improvements in their performance, reliability, and cost, including the architecture, design and test of next-generation S-band through Ka-band radios and a variety of antennas, as well as work with vendors on various design projects. You will be responsible for PCB layout projects and interface with cross functional teams - electrical, software and mechanical engineers to address challenging design issues. You will conduct environmental and EMC testing on communication subsystems and get them ready for flight. You will work closely with systems engineering, missions, and manufacturing teams to ensure mission success.
