Security Engineer

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 are seeking an experienced Governance, Risk, and Compliance (GRC) Engineer to own and scale our security and AI governance compliance posture as SpaceXSI grows. You will set the standards the organization builds to, design and implement controls, and automate the unglamorous parts of compliance so a fast-moving team can ship safely. The ideal candidate combines deep fluency across modern security and AI frameworks with GRC engineering skills: you translate control requirements into technical implementations, partner with engineers to bake compliance into architecture and CI/CD, and replace point-in-time checklist work with continuous, engineered assurance. You will collaborate across engineering, legal, product, and leadership to keep our AI systems audit-ready across enterprise, commercial, and public-sector environments.   This role may also include additional tasks and responsibilities as needed to support the team and evolving business priorities.

RESPONSIBILITIES:

• Own and execute security compliance implementation and audits across core frameworks including SOC 2, NIST CSF, NIST SP 800-53, ISO 27001, ISO 42001, and the EU AI Act, including control design, mapping, gap assessment, evidence collection, and remediation tracking.
• Build and maintain Compliance-as-Code and continuous compliance capabilities — policy-as-code, automated control validation, continuous evidence pipelines, and monitoring integrated into development and deployment workflows — so the company can move fast without cutting corners.
• Operate and extend GRC platforms (e.g., Vanta) as the system of record for controls, evidence, and audit readiness; integrate them with cloud, identity, and engineering tooling to reduce manual toil.
• Partner with engineering and architecture to embed compliance requirements early in design reviews; translate framework obligations into clear technical control narratives that satisfy auditors without slowing delivery.
