Senior Manager, Data Engineering @ Walmart

People Data Platform Powering Secure, Enterprise-Scale People Insights at Walmart .The People Data Platform team at Walmart owns the centralized People Data Lake that enables trusted, cross-domain people insights across the enterprise. We build and operate a scalable data platform on GCP, ingesting data from multiple source systems and transforming it through a robust medallion architecture to deliver high-quality, analytics-ready data.

Our team designs data and semantic models that empower HR, business, and analytics teams to make data-driven decisions at scale. In parallel, we lead the Data Security charter for the People Data Lake, implementing encryption, masking, and fine-grained access controls to protect sensitive data while ensuring compliant and governed access.

The Workforce Intelligence Platform (WIP) builds the access and experience layer on top of this foundation-enabling secure, personalized, and scalable analytics consumption. WIP combines query execution, dynamic access control (RLS, CLS, ABAC), and API-driven architecture to power dashboards, applications, and AI-driven data interactions.
