About the job
At SpaceX, we believe that a future where humanity explores the cosmos is infinitely more thrilling than one where we remain earthbound. We are on a mission to develop groundbreaking technologies that facilitate this vision, with our ultimate goal being the establishment of human life on Mars.
SENIOR SOFTWARE ENGINEER - SECURITY (STARSHIP)
Our Starship spacecraft and Super Heavy rocket, collectively known as Starship, represent the pinnacle of reusable transportation systems, engineered to transport crew and cargo to Earth orbit, the Moon, Mars, and beyond. Starship is poised to become the most powerful launch vehicle ever created, capable of carrying over 100 metric tons to Earth orbit.
As a Senior Software Engineer on the Starship Software team, you will play a crucial role in defining and constructing the security infrastructure that safeguards Starship vehicles, launch pads, operator UIs, and communications links against unauthorized access, data tampering, denial-of-service attacks, and other threats. You will collaborate closely with the broader software engineering team to implement and uphold secure software development practices. We are seeking candidates with a proven track record of delivering reliable software and a comprehensive understanding of modern Internet security designs, including the cryptographic fundamentals involved. You can see the broader perspective, prioritize effectively, and are comfortable working across various levels of abstraction. Ideally, you possess exceptional skills in one or more of the following areas:
- Secure Software Development Life Cycle
- Applied Cryptography
- Network Security
- Operating System Security
- Secure/Authenticated Boot
- Incident Response and Adversary Detection
- Vulnerability Research
Success in this role requires adaptability, clear communication, and the ability to foster productive relationships with other engineering teams. If you are passionate about building high-quality products, thrive on the challenges posed by adversaries, and aspire to make an impact on an interplanetary scale, you will thrive in our environment.
