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 making life multiplanetary and expanding consciousness to the stars.

SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.

ABOUT THE ROLE:

We protect the platform that runs X and SpaceXSI. We don’t just report issues, we actively look for real risks and exploits in our Kubernetes environments and turn them into durable fixes and tooling. You will secure the platform behind X and SpaceXSI’s infrastructure, products, and workloads. If you know pod and platform security, think in attack paths, and want to build the defenses that make the platform safer at scale, we want to hear from you.

We Value

• Understanding how Kubernetes can actually be abused, not only how it is configured
• Shipping practical controls and tooling over writing policy documents
• Least privilege and defense-in-depth at fleet scale
• Clear findings and fixes that platform teams can act on
• Safe, constrained validation that does not put production at risk

RESPONSIBILITIES:

• Secure the platform end to end: nodes, clusters, pods, roles, tokens, secrets, service-to-service communication, and the supply chain
• Find and remediate overprivileged permissions, dangerous pod and workload settings, and escalation paths in operators, admission, networking, identity, and monitoring
• Assess our own platform the way an adversary would, including container and pod breakout, privilege escalation, and movement across workloads, using safe and constrained validation, then fix what you find
• Design and build security tooling and automation, including AI-assisted analysis, that catches risky configuration and overprivilege before or after it ships
• Strengthen identity and secrets handling so workloads receive only the access they need
• Improve supply-chain security through secure base images, continuous scanning, and related controls
