Security Software Engineer (Starshield)

Spacex
Hawthorne, CA

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.

SECURITY SOFTWARE ENGINEER (STARSHIELD)

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.

  • Experienced in navigating large, complex, interactive systems

  • Flexibility, communicating clearly, and establishing and maintaining productive working relationships with other engineering teams

  • Excellent communication skills, both written and verbal

  • Ability to work both independently and in a team

  • Demonstrated ability to deal with ambiguity and to learn new technologies quickly

  • Advanced degree in a technical or engineering discipline

  • Active Top Secret, Top Secret SCI, or DOE Level Q clearance

ADDITIONAL REQUIREMENTS:


  • Must be willing to work extended hours and weekends as needed
