Sr. Manager, Software, Amazon Leo

Amazon Leo is building a next-generation low Earth orbit (LEO) satellite constellation to deliver global cellular connectivity directly to consumer devices. The Direct-to-Device (D2D) program enables standard mobile handsets to connect to Amazon Leo satellites without any hardware modification leveraging 3GPP Non-Terrestrial Network (NTN) standards. We are seeking a Distinguished Engineer to serve as the senior software technical leader for the D2D program responsible for driving the end-to-end software architecture development and delivery of satellite-based cellular communication systems.
This role demands a rare combination of deep expertise in 3GPP standards embedded systems engineering real-time operating systems radio access network (RAN) protocol stacks and computer hardware architecture. The Distinguished Engineer will set the technical vision mentor engineering teams and make critical architectural decisions that shape the performance reliability and scalability of the D2D satellite communication system.
