Security Engineer - GRC Sales

Palo Alto, CA;

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.

We are seeking a mid-to-senior Governance, Risk, and Compliance (GRC) professional focused on third-party risk management and customer trust. This role sits at the intersection of cybersecurity GRC, vendor management, and sales enablement: you will act as a security-minded presales engineer for the sales team, develop enough depth in the SpaceXSI technical environment to accurately complete customer vendor security questionnaires, join customer meetings as the security and compliance subject matter expert, and help operate third-party risk and vendor management processes.

The ideal candidate brings a cybersecurity and GRC perspective — fluent in how AI LLMs, CI/CD pipelines, identity and access management, Dev Ops, Dev Sec Ops , Kubernetes, and IT/AI governance actually work in production — and can translate that understanding into clear, credible answers for enterprise buyers without slowing deals or overstating our posture.

This role may also include additional tasks and responsibilities as needed to support the team and evolving business priorities.

• Support the sales organization as a cybersecurity/GRC presales partner: attend customer and prospect meetings, present our security and compliance posture, and answer technical and control-related questions with accuracy and judgment.
• Own and continuously improve responses to customer vendor security questionnaires, RFPs, SIG/CAIQ-style assessments, and due-diligence requests; maintain a reusable knowledge base of control narratives grounded in how SpaceXSI actually operates.
• Build and maintain working fluency across the SpaceXSI environment — AI/LLM systems and model governance, CI/CD pipelines, identity and access management, Dev Ops and Dev Sec Ops  practices, Kubernetes platforms, and governance of IT and AI environments — sufficient to answer customer questions and elevate appropriately to engineering when needed.
• Partner with Engineering, Security, Legal, and Product to keep questionnaire content, Trust Center materials, and security collateral current as architecture, controls, and certifications evolve.
• Translate customer security requirements into actionable internal asks; help distinguish must-have contractual or control commitments from unreasonable or out-of-scope demands.
• Contribute to policies, standards, and procedures related to third-party risk, customer assurance, and vendor security due diligence.
• Coordinate with the broader GRC and security teams on overlapping frameworks and evidence (e.g., SOC 2, ISO 27001, ISO 42001, privacy commitments) so external answers remain consistent with us internal control environment and GRC tooling (e.g., Vanta).
• Identify patterns in customer questionnaires and deal blockers; feed those insights back into product, engineering, and GRC roadmaps to reduce friction over time.
• Create and present concise status updates on questionnaire…
