From the original posting

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.

PRINCIPAL CYBERSECURITY ENGINEER (STARSHIELD)

At SpaceX we’re leveraging our experience in building rockets and spacecraft to deploy the Starshield constellation. Starshield is the world’s largest US government satellite constellation and is tasked with providing immediate access to critical intelligence and national security data for the US government anywhere on the globe. We design, build, test, and operate all parts of the system – n-space sensors, on-the-ground receivers, data processing, and the mesh network that provides lightning-fast connectivity to users around the world. We’ve only begun to scratch the surface of Starshield's global impact and are looking for best-in-class engineers to help us further our ambitious goals.

We are looking for a principal engineer to grow and lead a team of engineers who are developing and continually testing the cyber defenses of the Starshield network. This job will be hands-on and require breadth of experience in both software and security.

Continually run "red-team" style exercises to both discover vulnerabilities as well as to practice the tactics the team will deploy in the event of attacks.
  • Lead vulnerability discovery efforts across Starshield. Run internal bug hunts to search for undiscovered vulnerabilities. Develop a team culture of continual curiosity and open-ended exploration. Utilize the latest tools, including AI, to accelerate both discovery and fixing of bugs in the system.
  • Drive improvements into our incident discovery and response. This team will collaborate closely with the team building the internal systems we use to detect security events, and help drive improvement in our ability to discover active attempts at network intrusions.
  • Work across teams to get results. This team will collaborate closely with the engineers implementing security features into our systems, as well as the team developing our internal incident discovery tools.

BASIC QUALIFICATIONS:
