About The Position

We are seeking a Distinguished Software Engineer to define and drive the technical architecture for Walmart’s next-generation omni-channel Ad Experiences platform. This is one of the highest-impact individual contributor roles within Walmart Connect Engineering, focused on shaping the future of retail media experiences across Search, Display, Video, CTV, DOOH, and emerging physical retail surfaces. This role sits at the intersection of distributed systems, client rendering, ad serving, experimentation, measurement, video monetization, SDK architecture, and in-store commerce technology. You will partner across Product, Data Science, Infrastructure, Store Technology, Creative Platforms, and Ads Platform teams to build the unified experiences architecture powering Walmart’s future retail media ecosystem. You will solve problems that do not yet have industry playbooks — including unifying monetization surfaces across digital and physical environments, architecting low-latency rendering systems where every millisecond matters, scaling experimentation safely across billions of shopper interactions, and defining the technical foundation for the next decade of retail media innovation.

Architect cross-platform monetization frameworks enabling reusable rendering, experimentation, and measurement capabilities across all shopper surfaces.
Drive the evolution of Walmart’s first-party client rendering and measurement ecosystem, reducing dependency on third-party ad infrastructure.
Define rendering performance standards and latency SLAs including time-to-first-frame, render completion, video startup latency, and measurement timing integrity.
Shape Walmart’s unified video monetization architecture including SSAI, HLS ad stitching, quartile tracking, frame-accurate transitions, and playback resiliency.
Lead technical strategy for experimentation systems supporting statistically powered optimization across ad load, ranking, shopper engagement, and revenue yield.
Building a unified rendering architecture that seamlessly spans native apps, browsers, connected devices, in-store screens, and emerging retail surfaces.
Operating low-latency monetization systems where every additional millisecond directly impacts shopper engagement and revenue yield.
Scaling experimentation and ranking systems safely across billions of shopper interactions while preserving platform stability.
Delivering consistent measurement integrity across heterogeneous client environments, operating systems, and hardware generations.
Creating highly resilient distributed systems capable of operating reliably across large fleets of retail devices with remote observability and recovery
