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.
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.
As a GNC engineer on this team, you will bring a passion and expertise in areas like state estimation, spacecraft systems design, optimization, and software development to join the Starshield GNC team. Engineers on this team support various payloads through initial conception to on-orbit operation, with a focus on beam planning and algorithm development. You will be driving future hardware design and optimizing current payload performance through modeling and simulation. We are looking for engineers who enjoy solving complex problems, can work effectively in a fast-paced environment, and are passionate about advancing the space industry.
