About the role

The Off-Search Online Sourcing team builds real-time ad retrieval systems behind Amazon’s details pages and non-Search surfaces, delivering low-latency, high-throughput services and model serving infrastructure to surface relevant ads. The role emphasizes designing scalable distributed systems, collaborating with applied scientists, and driving production-grade retrieval models through A/B experiments.

Responsibilities

  • Design and develop high-throughput, low-latency services that retrieve and enrich ad candidates within strict latency budgets across Amazon's non-Search surfaces
  • Build and scale model serving infrastructure for real-time embedding inference, partnering with applied scientists to bring new retrieval models into production
  • Develop distributed indexing pipelines that build and refresh large approximate nearest neighbor search indexes across hundreds of millions of ads
  • Deliver real-time fulfillment signals — delivery speed, locality, return eligibility — that improve ad filtering and ranking quality for shoppers
  • Launch new retrieval models and indexes behind A/B experiments, analyze results, and use data to decide what ships to production
  • Deliver features end to end — from design and code reviews through implementation, deployment, monitoring, and on-call operations
  • Improve operational excellence through caching, graceful degradation, monitoring, and root-cause analysis
  • Mentor peers through code and design reviews, helping raise the engineering quality bar across the team
  • On a typical day you might review latency dashboards, build distributed pipelines, integrate embedding models, set up A/B experiments, review PRs, debug latency regressions, and monitor experiments for impact
