Sr Software Development Engineer, Sponsored Products and Brands

Amazon Amazon · Big Tech · NY +1 · Software Development

Senior Software Development Engineer to architect and lead the AI bidding platform for Amazon Sponsored Products and Brands. This role involves owning the technical strategy for real-time inference, GenAI agents, and experimentation infrastructure, focusing on sub-millisecond latency and autonomous learning at scale. Responsibilities include designing bidding engines, agentic intelligence layers using LLMs and RL, and experimentation systems, while also leading engineering efforts and mentoring teams.

What you'd actually do

  1. Own the architecture and multi-year technical roadmap for the full AI bidding platform—spanning the Tier 1 real-time proxy bidding engine, GenAI intelligence layer, and experimentation framework
  2. Design and lead the real-time proxy bidding engine that computes per-request bids on behalf of advertisers at sub-millisecond latency, scaling to billions of daily decisions
  3. Build and optimize ML inference infrastructure that serves model outputs at bid-request time, including latency budget allocation, graceful degradation, and fallback strategies
  4. Design and build scalable, low-latency agentic systems that process millions of advertiser signals to deliver AI-powered bidding optimization and intelligent campaign guidance
  5. Establish engineering standards, design patterns, and evaluation frameworks that govern how AI systems are built, tested, and validated across the Advertiser Controls organization
