How to Apply for RF Engineer - Part Time

at Planet

🏢 About Planet

Planet uniquely combines space technology with data analytics, operating the world's largest constellation of Earth-imaging satellites. They control the entire pipeline from satellite design to data delivery, offering engineers the rare opportunity to work on complete space systems. Their mission-driven focus on environmental stewardship and global impact makes them appealing to those wanting to apply RF engineering to solve real-world problems.

About This Role

This part-time RF Engineer role involves designing and optimizing communication systems for Planet's next-generation small satellite buses, specifically for the Pelican optical imaging and Carbon Mapper hyperspectral payloads. You'll contribute to complex RF systems including transceivers, PLL synthesizers, and other components for both space and ground station applications, directly supporting the collection of critical Earth observation data.

💡 A Day in the Life

A typical day might involve simulating RF circuit performance for satellite communication systems, collaborating remotely with hardware teams on component selection, and analyzing test data from prototype designs. You'll balance academic commitments with contributing to real satellite projects, potentially participating in virtual design reviews and troubleshooting RF issues affecting data downlink from Planet's constellation.
