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 an Embedded Senior Software Engineer on antenna systems validation team, you'll build the software backbone that powers our satellite ground infrastructure. You'll work at the intersection of distributed systems, automation, and hardware, creating tools that our engineers rely on every day. Your Impact: - Develop embedded software for the Phased Array Antenna units that are deployed to space - Design architecture of embedded software to be scalable and to support hardware testing for manufacturing - Build flexible test automation frameworks that validate complex antenna systems at scale - Create developer tools and APIs that accelerate hardware bring-up and system characterization - Develop simulation and modeling tools for efficient software integration testing - Automate everything: from firmware deployment to system configuration and validation - Collaborate across disciplines with systems architects, hardware engineers, and firmware teams Technologies & Skills: - Embedded software development in C, C++, Rust, or other modern languages - Scripting and test automation in Python or other languages - Embedded systems (Embedded Linux or RTOS) - Test automation frameworks and CI/CD pipelines - Proficiency with object oriented programming, design patterns and software architecture - Experience with networking protocols (such as TCP/IP, UDP), control and data plane concepts 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.
