Software Engineer
AST SpaceMobile
AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected.
Position Overview
The Software Engineer designs, develops, tests, and maintains software systems that support satellite development, ground systems, and operational infrastructure.
