About the role
The International Order Management & Fulfillment team at Walmart Global Tech builds the backend systems that power the complete order life cycle — from order creation through fulfillment and delivery — across international markets including Mexico, Canada, and other emerging geographies. The team works on large-scale, multi-market distributed systems that handle millions of transactions daily, and partners with Walmart International, which operates over 5,900 retail units outside the United States. This staff engineering role involves designing and scaling OMS/FMS backend services, driving platform convergence and technical strategy, and mentoring engineers.
What you will do
- Design 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
Skills used in this role
What the employer is looking for
- 10+ 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.
- Strong experience with NoSQL databases (Cassandra, Cosmos DB, MongoDB, or similar) and understanding of data modeling trade-offs for high-scale systems.
- Hands-on experience with event-driven architectures using Apache Kafka, message queues, and asynchronous processing patterns (CQRS, Event Sourcing).
- Experience building and operating distributed systems at scale — microservices, API gateways, service mesh, container orchestration (Kubernetes/WCNP).
- Familiarity with relational databases (SQL Server, PostgreSQL, MySQL) and caching layers (Redis, Memcached).
- Experience supporting multi-market / multi-tenant platforms with locale-aware business logic, internationalization (i18n), and cross-border considerations.
- Strong understanding of cloud-native development on Azure or GCP — managed services, infrastructure as code (Terraform), CI/CD pipelines.
- 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).
- Track record of leading technical initiatives, driving architecture decisions, and influencing without authority across teams.
- Option 1: Bachelor's degree in computer science, computer engineering, computer information systems, software engineering, or related area and 4 years' experience in software engineering or related area. Option 2: 6 years' experience in software engineering or related area.
