• Own the engineering execution and operation of CDW’s Data Security Posture Management (DSPM) capabilities, translating findings into actionable remediation.

• Analyze data exposure trends, leakage paths, and emerging threats, and produce metrics and insights that inform security priorities and decisions.

• Design and implement data protection architectures that scale across enterprise environments, focusing on secure implementation and practical delivery.

• Validate and enforce encryption, access controls, and data movement restrictions aligned to Zero Trust principles.

• Integrate data security controls with identity, endpoint, network, cloud, and SIEM platforms to improve visibility and reduce risk.

• Support data‑related security incidents and investigations, contributing to containment, remediation, and control improvements.

• Improve detection and response by correlating signals across Purview, DSPM, DLP, SIEM, and endpoint platforms.

• Drive operational excellence through automation, process improvement, and repeatable security engineering workflows.

• Act as a technical mentor and subject‑matter expert for data protection engineering, providing actionable guidance to Legal, Privacy, Cloud, Identity, and Architecture partners.
