About this job
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.
SR. SOFTWARE ENGINEER, SECURITY (STARSHIP)
SpaceX's Starship spacecraft and Super Heavy rocket (collectively referred to as Starship) represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world's most powerful launch vehicle ever developed, with the ability to carry in excess of 100 metric tons to Earth orbit.
As a Sr. Software Engineer on the Starship Software team, you will be responsible for defining and building the security infrastructure that protects Starship vehicles, pads, operator UIs, and communications links from unauthorized access, data tampering, denial-of-service, and other attacks. You will work closely with the larger software team to establish and maintain secure software development practices. 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:
- Secure software development life cycle
- 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.

- Own all aspects of software development, including design, testing, and integration to the mission
- Work with counterpart engineering teams to develop and maintain launch and vehicle software, crossing all required software domains necessary to implement and verify control of the pad, ship, and booster to meet mission objectives
- Define and lead impactful projects that enable the mission of Starship
- Continuously improve software standards and software engineering best practices within Starship Software
BASIC QUALIFICATIONS:
- Bachelor's degree in computer science, engineering, math, or science discipline and 4+ years of experience in software development; OR 6+ years of professional experience in software development in lieu of a degree
