Sr. Optical Engineer (Starshield)

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. SR. OPTICAL ENGINEER (STARSHIELD) Starshield leverages SpaceX’s Starlink technology and launch capability to support national security efforts. While Starlink is designed for consumer and commercial use, Starshield is designed for government use, with an initial focus on earth observation, communications, and hosted payloads. The SpaceX satellite engineering teams develop, produce, and deploy the most cutting-edge satellite free-space optical communication systems and observation payloads in the world. We are looking for engineers to contribute to the development of laser communications terminals and imaging products for the groundbreaking constellation of Starshield satellites. All SpaceX optical systems (laser communication terminal 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 Starshield optical engineer , you will be responsible for free-space optical system design, validation, and operation. You will shape the future of laser communication systems and directly contribute to mission-critical applications such as next-generation star tracking system for precise navigation in space environments.
