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.


As a member of our fast-paced Radiation Effects team, you will be responsible for ensuring avionics hardware performance across our fleet of vehicles (Dragon, Falcon, Starship, Lunar Human Landing System, etc.) through some of the harshest and varied radiation environments imaginable. In order to ensure maximum reliability in an ionizing radiation environment, the Radiation team at SpaceX performs exhaustive analysis, design, and test at the component, board, unit, and subsystem levels with extensive opportunity to interact with a vast array of rocket and spacecraft hardware and electronics. As one of the few teams required to interface with the design, manufacturing, integration, and mission operations teams, we play a critical role in the development of our systems as we advance our efforts towards broadband satellite internet and safe, reliable, inexpensive, and innovative access to space. This work all supports our fundamental goal of expanding human space exploration capabilities and establishing a permanent human presence on the moon and Mars.
