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.


The SpaceX Ground Segment team is responsible for supporting a wide array of communications needs. They support and deploy our worldwide network of ground stations, own all launch site and recovery RF communications and optical tracking, and facilitate all Starlink Telemetry, Tracking, and Control (TT&C). For all real-time operations of Falcon, Dragon, and Starship, the team facilitates NASA flight operations interfaces and network integration, as well as operational voice, mission control video, and communications readiness testing.

The successful candidate will drive the design and operations of our ground station network, operational systems, and partner interfaces (such as NASA) with an unrelenting drive toward reliability and automation. This network is critical to operations throughout all phases of a mission, providing command, telemetry, video, and voice communications. This role will be critical as the team develops the infrastructure to support lunar and Mars missions.

The ideal candidate will be flexible, possess broad skills across hardware installation, networking, monitoring, and software deployment/development, and flourish in a fast-paced and challenging environment. You should be a self-starter that is able to take initiative and approach traditional problems in novel ways.
