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 distributed platform services and APIs using Java and Python, applied against Kubernetes or equivalent cloud-native infrastructure.

• Apply system design and low-level design (LLD) rigor to 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 data engineering work when needed: contribute to Spark-based data pipelines and processing jobs, working directly in GDF's data engineering codebase alongside platform work.

• Build AI, GenAI, and agentic-powered platform capabilities: intelligent developer tooling, workflow automation, agentic services, and AI-assisted operational tooling (monitoring, incident triage, capacity planning).

• Own reliability, scalability, and observability for the services you build - service-level objectives, distributed tracing, alerting, and incident response - with a strong Operational Excellence / Engineering Excellence discipline.

• Contribute to architecture and system design decisions across microservices, event-driven systems, and enterprise integrations, with an eye toward how platform choices affect downstream data engineering workloads.

• Partner with data engineers, data scientists, and ML engineers to ensure the services you own expose the right primitives for data pipelines, feature stores, and model-serving paths.

• Participate actively in architecture reviews, design reviews, code reviews, and production readiness reviews for a team building process from scratch.

• As a Senior engineer, bring strong technical judgment to design and code reviews within your immediate team and area of ownership, mentor early-career engineers, and help raise the bar for engineering quality - without needing a formal management title.

• Stay current on emerging platform, cloud, and AI/agentic technologies, and propose where they could pragmatically improve reliability, productivity, or business value within your team's scope.

What You'll Bring

• Genuinely hands-on coding: 5+ years of professional software engineering experience building and operating distributed platforms; strong proficiency in Java and Python is required - comfortable writing, reviewing, and debugging production code. Additional experience with Go, C++, or Scala is a plus.
