Distinguished, Software Engineer

Walmart Walmart · Retail · Sunnyvale, CA

Distinguished Software Engineer to define and drive the technical architecture for Walmart’s next-generation omni-channel Ad Experiences platform, focusing on retail media across Search, Display, Video, CTV, DOOH, and emerging physical retail surfaces. This role involves architecting low-latency rendering systems, scaling experimentation, and defining the technical foundation for retail media innovation.

What you'd actually do

  1. Define the long-term architecture for Walmart’s unified omni-channel Ad Experiences platform spanning Mobile, Web, CTV, Video, and DOOH environments.
  2. Lead the design of highly performant client-side rendering systems and SDKs powering billions of ad requests and rendering events annually.
  3. Architect cross-platform monetization frameworks enabling reusable rendering, experimentation, and measurement capabilities across all shopper surfaces.
  4. Drive the evolution of Walmart’s first-party client rendering and measurement ecosystem, reducing dependency on third-party ad infrastructure.
  5. Define rendering performance standards and latency SLAs including time-to-first-frame, render completion, video startup latency, and measurement timing integrity.
