Run Time Platforms (RTP), a division of Global Technology Platform (GTP), builds the core products and platforms that enable application teams to deploy, operate, and scale services consistently across Walmart’s runtime environments. RTP’s mission is to reduce operational complexity and accelerate delivery by providing secure-by-default, reliable, and standardized runtime capabilities—so teams can focus on building customer and associate experiences rather than reinventing infrastructure.
Within RTP, the Service Registry & Service Mesh team provides the foundational connectivity layer for modern distributed systems. We build and operate platforms that make it easy for services to find each other, communicate securely, and be governed consistently across clusters, environments, and markets. Our work underpins service-to-service communication for a large fleet of microservices and supports high-throughput, latency-sensitive workloads.
As a Distinguished Engineer on the RTP Service Mesh team, you will lead the architecture, strategy, and technical execution of a service mesh platform (Istio or similar) supporting large-scale microservices workloads. You will operate at enterprise scope—defining reference architectures, driving multi-cluster patterns, ensuring operational excellence, and partnering with security, networking, SRE, and product teams to deliver a platform that is secure-by-default and easy to adopt.
You will also mentor senior engineers and influence technical decisions across GTP to raise the bar on platform reliability, performance, and developer experience.
