• Architect and govern data security controls within Microsoft Fabric, including workspace-level and item-level permissions, sensitivity labels, and One Lake security.
• Design role-based access control (RBAC) and attribute-based access control (ABAC) strategies across Azure Data Factory, Azure Synapse, Azure Databricks, and Azure SQL.
• Implement and operationalize Microsoft Purview for data catalog governance, data lineage, and automated sensitivity classification across hybrid and multi-cloud data estates.
• Configure and manage Azure Private Endpoints, VNet integration, and network security groups for data services to eliminate public exposure.
• Oversee encryption strategies including Azure Key Vault integration, customer-managed keys (CMK), and data-at-rest / data-in-transit encryption standards.
• Partner with identity teams to enforce Entra ID Conditional Access policies, Privileged Identity Management (PIM), and managed identities for data service authentication.
• Lead the implementation and tuning of Microsoft Defender for Cloud data security posture management (DSPM) capabilities.
• Architect and implement Unity Catalog as the enterprise-wide data governance layer across Databricks workspaces, including metastore design, catalog/schema/table-level permissions, and row/column-level security.
• Design Databricks workspace security including network isolation (no-public-IP, v Net injection, private link), cluster policies, and IP access lists.
• Define and enforce Databricks credential passthrough, service principal governance, and OAuth integration with Azure Entra ID.
• Implement dynamic data masking and column-level security policies within Unity Catalog to protect PII, PHI, and sensitive financial data.
• Establish Delta Lake security patterns including table ACLs, fine-grained access control, and audit logging strategies via Databricks system tables.
• Oversee the security of Databricks workflows, notebooks, and job clusters, including secrets management integration with Azure Key Vault-backed secret scopes.
• Conduct security reviews of MLflow models and Feature Store configurations to address data leakage risks in ML pipelines.
• Ensure data platform compliance with relevant regulatory frameworks including GDPR, CCPA, HIPAA, SOC 2 Type II, and PCI-DSS where applicable.
• Design and maintain audit trail and data access logging architectures across Microsoft and Databricks platforms.
• Conduct regular security risk assessments, gap analyses, and maturity evaluations of the data security program.
• Develop and maintain security runbooks, policies, and standards documentation for data platform operations.
• Coordinate with legal, compliance, and privacy teams to respond to data subject access requests (DSARs) and regulatory inquiries.
• Serve as the primary security advisor to data engineering, analytics engineering, and BI teams throughout the development lifecycle.
• Lead security architecture review boards for new data initiatives, third-party data integrations, and major platform changes.
• Develop and lead a structured mentoring program for junior and mid-level engineers and architects, providing one-on-one coaching, career guidance, and skills development roadmaps tailored to each individual’s growth goals.
• Conduct regular knowledge-sharing sessions, lunch-and-learns, and internal workshops to upskill teams on evolving data security threats, tooling, and compliance requirements across the Microsoft and Databricks ecosystems.
• Partner with engineering managers and HR to define data security competency frameworks, leveling guides, and certification pathways that support talent development and retention across the data platform organization.
• Establish and maintain a community of practice around data security, fostering peer learning, documentation culture, and cross-team collaboration on shared security challenges and architectural patterns.
• Collaborate with Sec Ops and SOC teams to build data-specific detection rules, incident response playbooks, and forensic investigation capabilities.
• Present security posture, risk findings, and remediation roadmaps to executive leadership and board-level stakeholders.
