Distinguished, Software Engineer

Position Summary

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 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, and creative platforms to build the unified experiences architecture powering Walmart’s future retail media ecosystem.

Walmart Connect is a leading retail media platform. The Ad Experiences organization owns all shopper-facing monetization surfaces across digital and physical Walmart environments, building rendering engines, client SDKs, experimentation platforms, and measurement systems that serve more than 170,000 in‑store screens.

• Define the long‑term architecture for Walmart’s unified omni‑channel Ad Experiences platform spanning Mobile, Web, CTV, Video, and DOOH environments.
• Lead the design of highly performant client‑side rendering systems and SDKs powering billions of ad requests and rendering events annually.
• 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.
• Build a unified rendering architecture that seamlessly spans native apps, browsers, connected devices, in‑store screens, and emerging retail surfaces.
• Operate low‑latency monetization systems where every additional millisecond directly impacts shopper engagement and revenue yield.
• Scale experimentation and ranking systems safely across billions of shopper interactions while preserving platform stability.
• Deliver consistent measurement integrity across heterogeneous client environments, operating systems, and hardware generations.
• Create highly resilient distributed systems capable of operating reliably across large fleets of retail devices with remote observability and recovery.

• 12+ years of software engineering experience building large‑scale distributed systems or client platforms.
• Recognized technical leadership driving architecture across multiple organizations or product domains.
• Deep expertise in one or more of the following areas:
  AdTech, video platforms, distributed systems, SDK architecture, rendering engines, experimentation systems, or large‑scale client applications.
• Strong hands‑on engineering background with the ability to operate at both strategic and implementation levels.
• Experience architecting highly performant systems operating under strict latency, scale, and reliability constraints.
• Experience driving cross‑functional technical strategy across Product, Infrastructure, Data Science, and Platform Engineering teams.
• Excellent communication skills with ability to influence senior technical and executive stakeholders.
• Experience in Retail Media, AdTech, Search monetization, Video monetization, CTV, or DOOH platforms.
• Experience building first‑party ad serving or measurement systems.
• Strong understanding of experimentation systems, ranking systems, auction mechanics, or personalization.
• Experience with video playback technologies including HLS/DASH, SSAI, and streaming monetization.
• Experience with cross‑platform SDKs spanning iOS, Android, Web, Linux, embedded systems, or connected devices.
• Familiarity with privacy‑safe measurement and MRC‑compliant instrumentation.
• Experience operating platforms at Walmart‑scale or comparable internet‑scale…
