About The Position

We’re part of Walmart’s Omni Tech organization, building the distributed systems that power retail operations for more than 6,000 stores across 26 countries and 55 banners — including Canada, Central America, Chile, China, and Mexico. Our work touches millions of customers every day, at truly global scale. We’re looking for a Full Stack Engineer who is passionate about building impactful solutions across the entire technology stack—from intuitive user experiences to scalable backend platforms. In this role, you'll spend approximately 70% of your time designing and developing applications and automation solutions that support Walmart Marketplace's Business, Product, Program, Engineering, and Operations teams. You'll leverage technologies such as Python, Java, React, and React Native to build tools that improve operational efficiency, enhance decision-making, and solve complex business challenges. The remaining 30% of your time will focus on building and enhancing backend services and data platforms that power these applications. You'll work with large-scale datasets and distributed systems across multiple platform services to create reliable, scalable, and high-performing solutions. This role goes beyond traditional software engineering. You'll partner closely with Marketplace Business, Product, Operations, Support, and Engineering teams to solve complex business and technical challenges, investigate high-impact platform and operational issues, and build automation, AI-powered solutions, and internal tools that drive efficiency at scale. You'll have the opportunity to work on executive escalations and ambiguous business problems that require deep analysis, strong technical judgment, and end-to-end ownership. You'll play a key role in influencing architectural decisions, defining the long-term direction of our systems, and translating business needs into scalable technology solutions that deliver measurable impact for Walmart Marketplace.
