Job description

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. The Starshield team is building highly reliable in-space mesh networks, designing secure systems to guarantee access to space, designing next-gen communication and sensing software, and more.

As a Security Software Engineer you will influence the security of software across our product lines. We are looking for people with a track record of shipping reliable software and who have a broad understanding of the security design of today's Internet, including the cryptographic primitives involved. You see the big picture, prioritize accordingly, and are comfortable with working at different levels of abstraction. Ideally, you have notable skills in one or more of the following:

  • Software engineering
  • Applied cryptography
  • Network security
  • Operating system security
  • Secure/authenticated boot
  • Incident response and adversary detection
  • Vulnerability research

Being flexible, communicating clearly, and establishing and maintaining productive working relationships with other engineering teams are paramount to success. If you are passionate about building quality products, love the challenges of outsmarting adversaries, and want to make an impact on an inter-planetary scale, then you will fit right in.

RESPONSIBILITIES:

  • Design and build security infrastructure for Starshield, including cryptographic services and other security-critical services
  • Develop security features for Starshield systems, including our router, dish, gateways, and satellites
  • Design security into factory processes and provide network services in support of this
  • Maintain existing production systems and improve security posture via both direct implementation and recommendations to other teams
  • Build prototypes and help identify, design, and test security improvements

BASIC QUALIFICATIONS:

  • Bachelor's degree in computer science or another STEM discipline; OR 2+ years of professional experience in security software development in lieu of a degree
  • Experience with one or more software development languages (i.e. Python, C++, Golang)
  • Experience designing and implementing security solutions for operating systems, distributed systems, or other enterprise/large-scale infrastructure

PREFERRED SKILLS AND EXPERIENCE:

  • Experience contributing security improvements to complex systems
  • Experience working with special purpose security hardware such as trusted platform modules (TPMs) and hardware security modules (HSMs)
  • Fundamental understanding of network protocols; including the TCP/IP stack as well as UDP based protocols
  • 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
  • This position requires successfully obtaining and maintaining a Top Secret Security Clearance as a condition of employment. While the clearance may not be immediately necessary upon hire, we encourage you to initiate the application process promptly upon accepting this offer.
