Team and Role Overview

Relativity seeks a highly talented RF Engineer to join a rapidly growing space startup. This position will provide outstanding technical engineering to ensure the Terran 1 launch vehicle S-Band telemetry system and GPS receivers maintain sufficient performance throughout flight. The RF Engineer will be the owner of the S-band RF transmitter, all vehicle antennas including GPS antennas, and RF link budgets. In addition, they will also be responsible for regulatory licensing, and coordinating ground stations for mission telemetry coverage at the launch site and around the world as needed.

The Mission/Outcomes and Objectives

Our mission is to change people’s conception of the way rockets are built and flown. As the RF Engineer, you will be responsible for ensuring the RF link between the Terran 1 launch vehicle and our ground receivers provide critical vehicle performance metrics and on-board video data. Additionally, you will be responsible for all antennas on the launch vehicle providing RF links for telemetry and GPS.
