About Team
The International Technology team enables Walmart's stores and eCommerce operations across the world, with platforms used in most markets where Walmart has a presence outside the US.

- Architect and deliver scalable backend systems – Lead the end-to-end design and implementation of high-throughput, low-latency Java microservices handling item catalog ingestion, validation, transformation, and offer publishing across global markets.
- Drive technical strategy and engineering standards – Define and champion architectural patterns, coding standards, and best practices for the team; conduct design reviews, guide ADRs (Architecture Decision Records), and influence platform-level decisions across the Global Marketplace engineering organization.
- Lead complex problem-solving across distributed systems – Own the resolution of critical production issues, performance bottlenecks, and systemic reliability gaps; apply deep expertise in distributed systems, event-driven architectures (Kafka), NoSQL data stores (Cosmos DB), and cloud-native deployments (Kubernetes/WCNP on Azure).
- Mentor and grow engineering talent – Coach senior and staff engineers through pair programming, code reviews, and design discussions; help build a culture of technical rigor, ownership, and continuous learning within the team.
- Collaborate cross-functionally to deliver business outcomes – Partner with Product Management, Data Engineering, Platform teams, and global market stakeholders to translate complex business requirements into robust, maintainable technical solutions with measurable impact.
What you'll bring:
- Deep Java and distributed systems expertise – 13+ years of software engineering experience with strong proficiency in Java (8/11/17+), Spring Boot, microservices architecture, REST and gRPC APIs, and high-scale distributed systems design patterns.
- Event-driven and streaming systems experience – Hands-on experience building production systems with Apache Kafka or equivalent event streaming platforms; solid understanding of eventual consistency, idempotency, and at-least-once/exactly-once processing semantics.
- Cloud-native and Azure platform expertise – Experience designing and operating services on Kubernetes-based platforms (WCNP/Azure AKS or equivalent); hands-on exposure to Azure cloud services including Azure Cosmos DB, Azure Service Bus, and Azure Monitor; familiarity with observability tooling (metrics, logging, distributed tracing), CI/CD pipelines, and SRE principles.
- Principal-level leadership and communication skills – Proven track record of leading technical roadmaps, influencing without authority across teams, facilitating alignment between engineering and business stakeholders, and mentoring engineers to accelerate their growth.
