About the role
The UGC – Ratings & Reviews team at Walmart Global Tech builds and operates the next-generation UGC 2.0 platform that powers customer ratings, written reviews, image reviews, video reviews, and seller reviews across Walmart's web and mobile experiences.
UGC is a cloud-native platform built on an Event-Driven Architecture (EDA) using Golang microservices, Kafka, Cosmos DB, BigQuery, Kubernetes, and Azure/GCP. The platform enables real-time ingestion, moderation, storage, and delivery of customer-generated content at Walmart scale while providing high availability, low latency, and operational resilience.
Customer-generated content is a key driver of customer trust, product discoverability, and purchase conversion. As Walmart continues to modernize its eCommerce platform, UGC serves as the strategic foundation for delivering scalable, reliable, and innovative customer experiences.
