About the role

Original posting from SpaceX via Greenhouse

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.

NEW GRADUATE ENGINEER, SECURITY SOFTWARE - '26/'27 (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

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

Graduating in the class of 2026 or 2027

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.
