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. The Leo Network Observability team designs, implements, and operates network visualization, monitoring, and analytics services for Leo Network Operations. Our scope spans satellites, customer terminals, gateways, and terrestrial network infrastructure that connects into public and private networks. We deliver user interfaces, agentic AI agents, temporal graph neural network outage prediction, and data streaming solutions. We are looking for a talented Senior FEE III to help design and develop Network Observability solutions for operating our advanced global telecom service via space and terrestrial networks. As a front-end engineer on this team, you will collaborate with a mix of software and network engineers and scientists to create user experiences that increase our end-to-end ability to deliver high quality, secure and fault tolerant software used in Low Earth Orbit (LEO) satellites, ground gateways, and Consumer/Enterprise class customer terminals. The candidate must have expertise with modern web development practices and will have demonstrated the capability to deliver best-in-class user experiences that solve some of today's hardest visualization challenges. Export Control License: This position may require a deemed export control license for compliance with applicable laws and regulations.
