About The Position

Welcome to Planet. We believe in using space to help life on Earth. Planet designs, builds, and operates the largest constellation of imaging satellites in history. This constellation delivers an unprecedented dataset of empirical information via a revolutionary cloud-based platform to authoritative figures in commercial, environmental, and humanitarian sectors. We are both a space company and data company all rolled into one. Customers and users across the globe use Planet's data to develop new technologies, drive revenue, power research, and solve our world’s toughest obstacles. As we control every component of hardware design, manufacturing, data processing, and software engineering, our office is a truly inspiring mix of experts from a variety of domains. We have a people-centric approach toward culture and community and we strive to iterate in a way that puts our team members first and prepares our company for growth. Join Planet and be a part of our mission to change the way people see the world. Planet is a global company with employees working remotely world wide and joining us from offices in San Francisco, Washington DC, Germany, Austria, Slovenia, and The Netherlands. About the Role: 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. This role will require you to be physically present at our headquarters in San Francisco, CA, 3 days a week.
