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 DSP engineer on the Starshield satellite team, you will be a part of a mission to provide global connectivity to the US government including immediate access to critical intelligence and national security data anywhere it is needed. You will work with a team of RF engineers, DSP engineers, software engineers, hardware engineers, and end users to design and build RF communications systems to provide essential data to global users. You will work in a highly collaborative and fast-paced environment, where we are exploring unsolved problems and applying the SpaceX mindset of iterating rapidly to go from design and demo to operational capability at lightning pace.

An active Top Secret security clearance, or ability to obtain one, is desired but not required.
