## Description

Amazon Leo is Amazon's low Earth orbit satellite network. Our mission is to deliver fast, reliable internet connectivity to customers beyond the reach of existing networks. From individual households to schools, hospitals, businesses, and government agencies, Amazon Leo will serve people and organizations operating in locations without reliable connectivity.

As a Radiation Effects Engineer, you will join a small team focused on the qualification of electronics components used on a satellites constellation and take an active role in root-cause analysis of on-orbit events. Your day-to-day work will include collaborating with design engineers to coordinate radiation testing and drive mitigation strategies of common error modes, analyzing satellite enclosures for TID robustness, and review on-orbit data to determine root-cause of common errors.

Export Control Requirement: Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum., Define, collect, and analyze heavy ion, proton, and TID testing to qualify components against space radiation and build a radiation tested component database.

 - Develop processes for managing component and satellite hardware test results and documentation
 - Collaborate closely with electronic design teams to quantify radiation risk and develop mitigations schemes to radiation events.
 - Lead root-cause analysis of on-orbit radiation events. Develop tools and dashboards to organize and visualize on-orbit events.
