SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars.OPTICAL TRANSCEIVER ENGINEER – HIGH SPEED LINKS, SATELLITES (STARLINK) The Starlink Space Lasers team develops, produces and deploys systems for transferring data over optical media. We are looking for engineers to contribute to the development of optical physical layer systems for the groundbreaking constellation of Starlink satellites. All SpaceX optical systems (transceivers and other optical products) require a blend of theoretical expertise, practical implementation skills, and a passion for solving complex problems in real-time, resource-constrained systems. As a SpaceX optical datacom engineer, you will be responsible for optical datacom system design, validation, and operation. You will shape the future of optical data communications and interconnect systems and directly contribute to the optical networks that convey high bandwidth data within our payloads.
