Embedded Software Engineer, OS/Platform

About the role

This position is centered on the Starlink program, concentrating on the software architecture that supports a large satellite constellation delivering service to over 9 million users. The role holder will manage the complete lifecycle of platform software, guiding it from the initial hardware bring-up phase through to on-orbit operations for both spacecraft and ground infrastructure components. You will be responsible for maintaining and updating core software stacks such as Linux, Buildroot, and u-boot within internal branches. Security is a critical aspect of this position, requiring implementation and maintenance of secureboot and runtime security measures for satellite components. A significant portion of the work involves overseeing spacecraft Ethernet networking and overall connectivity to ensure reliable communication. You will also create and deploy robust software update processes that are essential for spacecraft operations and longevity. Furthermore, the role includes developing and maintaining the OS/Platform test infrastructure to validate software integrity. Collaboration is key as you work with Silicon, Electrical, and Application Software teams to transition hardware prototypes successfully into orbit. This position demands ownership of the entire software stack, ensuring reliability and performance in the harsh environment of space.
