• Contribute to Data Security Posture Management (DSPM) efforts by helping discover where sensitive data resides, who has access to it, and whether it is properly protected
• Partner on data security governance activities, including policy alignment, exception handling, metrics, and continuous improvement initiatives
• Support audit and regulatory responses (e.g., evidence gathering, control mapping, and issue remediation) in collaboration with Risk, Privacy, and Corporate Security stakeholders
• Help define and track KPIs and KRIs to provide visibility into data security effectiveness, coverage, and risk trends
• Act as a strong cross functional partner, balancing security, compliance, and business enablement while supporting Mastercard’s Zero Trust data strategy

• Comfort working across audit, risk, privacy, and technology teams
• Strong written and verbal communication skills, with the ability to explain security concepts clearly to diverse audiences
