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, DevOps, DevSecOps, 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.
