About Team: Order Life Cycle / Fulfillment Management About the RoleWe are looking for a Staff Software Engineer to join our International Order Management & Fulfillment team. You'll design, build, and scale the backend systems that power the complete order life cycle — from order creation through fulfillment and delivery — across multiple international markets including Mexico (MX), Canada (CA), and other emerging geographies. This is a high-impact role where you'll work on large-scale, multi-market distributed systems that handle millions of transactions daily. You'll drive technical strategy, mentor engineers, and partner closely with product, architecture, and cross-functional teams to deliver world-class order management and fulfillment capabilities for Walmart International. What You'll DoDesign and build highly scalable, resilient backend services for Order Management Systems (OMS) and Fulfillment Management Systems (FMS) serving multiple international markets (MX, CA, and beyond). Architect and implement multi-tenant / multi-market solutions that support locale-specific business rules, tax regulations, fulfillment models, and delivery SLAs across geographies. Lead the technical design of core order life cycle domains: order capture, orchestration, inventory reservation, fulfillment routing, shipping, and post-order flows (returns, cancellations, modifications). Build event-driven, microservices-based architectures using Java/Spring Boot, Kafka, and NoSQL databases to ensure high throughput and low latency at scale. Drive platform convergence efforts — unifying order and fulfillment platforms across markets to reduce duplication and accelerate speed-to-market for new geographies. Partner with Data Engineering and Data Science teams to enable AI/ML-driven capabilities such as intelligent order routing, demand forecasting integration, and anomaly detection in fulfillment pipelines. Champion engineering excellence: code quality, observability, testing strategies, CI/CD best practices, and production readiness. Mentor and grow engineers on the team through design reviews, pair programming, and technical leadership. Contribute to incident response and operational excellence for Tier-0/1 systems critical to Walmart International's ecommerce operations What You'll Bring10+ years of software engineering experience with a strong focus on backend development. Deep expertise in Java and Spring Boot ecosystem — Spring MVC, Spring Cloud, Spring Data, Spring Security.

Experience with AI/ML literacy and applications — understanding of how machine learning models are integrated into production systems, leveraging GenAI/LLM tools for developer productivity (e.g., code generation, automated testing, intelligent debugging), and staying current with AI-driven engineering practices. Exposure to observability stacks — Grafana, Splunk, Prometheus, distributed tracing (Jaeger/Zipkin). Experience with feature flagging, A/B testing, and progressive rollout strategies for multi-market deployments. Proficiency in system design, domain-driven design (DDD), and API design (REST, gRPC, GraphQL).
