As a Senior Software Engineer, you’ll own the design and delivery of scalable backend services and data pipelines that power store operations, merchandise location management, and electronic shelf label infrastructure at this scale.
You'll also contribute to the React Native mobile surfaces that associates use on the floor every day.
Design and build high-throughput, event-driven microservices using Java and Spring Boot that serve as the backbone for the SSOT of merchandise locations — a dataset of 600M+ records growing with every new DSL rollout.
Architect and maintain Kafka-based event streaming pipelines handling item location changes, replenishment updates, and ESL tag events at >10K TPS peaks across thousands of stores.
Own the full data lifecycle — from schema design and migrations (MySQL) to JPA/Hibernate access patterns through shared data access layers — optimized for read/write performance at massive scale.
Build resilient service integrations using Resilience4j (circuit breakers, retry policies, rate limiting) ensuring downstream consumers — operating at peak TPS — experience consistent, low-latency responses.
Implement and maintain multi-module Maven builds across a 12+ module microservice architecture.
Write production-ready code with strong observability — structured logging to OpenObserve/Splunk, meaningful metrics, and alerting that matters at scale.
Contribute to CI/CD pipelines via Looper (Jenkins) for automated build, test, and deployment workflows.
Deploy and operate services on Kubernetes (KITT), understanding pod lifecycle, scaling strategies, and deployment configurations for high-availability systems.
Build and maintain features in the mod-flex React Native mini-app running inside the Me@Walmart (Allspark) container.

Requirements

Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience
4+ years of software engineering experience with a strong backend focus
Strong proficiency in Java and Spring Boot — you’ve built and shipped production microservices
Hands-on experience with Kafka or similar event streaming platforms — ideally at high-throughput, production scale
Solid understanding of relational databases (MySQL or equivalent) — schema design, query optimization, and ORM patterns tuned for large datasets
Demonstrated ability to design systems with high availability and performance in mind — you think about consistency, latency, and failure modes
Experience with REST API design — building and consuming APIs across service boundaries at scale
Familiarity with Kubernetes and containerized service deployments
Experience with CI/CD pipelines (Jenkins, Looper, or equivalent)
Working knowledge of frontend development — React, React Native, or TypeScript experience is a plus
Strong debugging and observability skills — comfortable querying logs and tracing issues in production
Comfortable in a distributed team environment with asynchronous communication.
