About Team

GDF (Global Data Foundation) is part of Walmart's AI & Data organization - the team building the foundational data platforms that power AI, analytics, and decision-making across every Walmart banner and geography, from supply chain and merchandising to customer experience and enterprise AI agents. Our newly created platform team is chartered with building next-generation data infrastructure at Walmart scale: reliable, high-throughput data pipelines, distributed processing systems, and platform capabilities that downstream teams across Walmart depend on every day.

What You'll Do

• Design, build, and operate batch and streaming data pipelines using Spark, Java, and Python, processing data at Walmart scale.
• Apply solid software engineering fundamentals - clean architecture, automated testing, CI/CD, code review discipline - to data engineering work; this is a software engineering role that specializes in data, not a script-writing role.
• Apply system design and low-level design (LLD)



rigor to data and platform problems - evaluating dependencies, trade-offs, failure modes, scalability, and cost before writing a line of code, with support from Staff/Principal engineers on the most ambiguous or cross-team problems.
• Flex into platform/software engineering work when needed: contribute to services, APIs, and distributed systems that data pipelines depend on, working directly in GDF's broader platform codebase.
• Apply AI, GenAI, and agentic capabilities directly to data platform problems: embeddings/vector search for data discovery, LLM-assisted data quality and anomaly detection, agentic pipeline monitoring, AI-assisted schema and lineage documentation.
• Partner with data scientists and ML engineers to build feature pipelines, model-serving data paths, and the data infrastructure that MLOps depends on.
• Own data quality, observability, and governance for the pipelines and datasets you build, with a robust Operation
