Description
Architect the AI bidding platform that powers billions of daily ad decisions for millions of advertisers—from a first-time small business owner launching their debut campaign to enterprise brands managing hundreds of millions in spend. You'll own the technical strategy end-to-end: real-time inference at sub-millisecond latency, GenAI agents that learn and optimize autonomously, and experimentation infrastructure that proves it all works at scale.Amazon Sponsored Products and Brands is seeking a Senior Software Development Engineer to join our Advertiser Controls team. You will set the architectural direction, make high-judgment technical decisions independently, and raise the engineering bar across the organization.
What You'll Own
- Real-Time Proxy Bidding Engine (Tier 1) — Define and lead the engine that computes per-request bids at sub-millisecond latency, build the ML inference infrastructure serving model outputs at bid-request time, and establish patterns that scale to billions of daily decisions
- GenAI & Agentic Intelligence Layer — Architect AI systems using LLMs, reinforcement learning, and preference optimization that learn from bidding outcomes and advertiser feedback; design agent-to-agent protocols, session lifecycle management, and model fine-tuning pipelines
- Experimentation Infrastructure — Design systems supporting multiple concurrent online experiments, enabling the team to test bidding strategies and AI optimization approaches with speed and statistical rigor
How You'll Lead
- Identify what needs to be built before it becomes obvious and frame technical strategy for ambiguous challenges
- Drive alignment across engineering, product, and science teams
- Mentor and develop engineers; represent the team in cross-org design reviews and principal engineering forums
- Make independent architectural decisions on hard problems—escalating only when broader organizational alignment is required
Why You'll Love It
- Your decisions directly shape how hundreds of millions of customers discover products on Amazon
- You'll define the GenAI architecture standard for the broader Sponsored Products organization
- You'll work at the intersection of real-time systems, ML infrastructure, and agentic AI—at a scale few teams in the industry can offer
Key job responsibilities
- 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
- 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
- Build and optimize ML inference infrastructure that serves model outputs at bid-request time, including latency budget allocation, graceful degradation, and fallback strategies
- Design and build scalable, low-latency agentic systems that process millions of advertiser signals to deliver AI-powered bidding optimization and intelligent campaign guidance
- Establish engineering standards, design patterns, and evaluation frameworks that govern how AI systems are built, tested, and validated across the Advertiser Controls organization
- Drive architectural decisions that span multiple engineering teams, resolve cross-system dependencies, and unblock delivery at the organizational level
- Frame ambiguous, high-stakes technical problems into clear engineering strategies with well-defined milestones and success criteria
- Proactively identify and eliminate systemic operational risks, technical debt, and architectural gaps—delivering permanent, scalable solutions rather than tactical fixes
- Mentor and develop engineers across the team; conduct design reviews that elevate technical quality and raise the bar for system thinking
- Represent the team in cross-organizational design reviews and principal engineering forums, influencing technical direction beyond your immediate scope
- Partner with product managers, applied scientists, and principal engineers to translate advertiser needs and business strategy into executable technical plans
