Software Development Engineer - New York | Amazon Job

Job Description

Build the AI-powered bidding controls and recommendation systems that help millions of advertisers optimize their campaigns on Amazon — developing agentic architectures, model fine-tuning infrastructure, and experimentation platforms that directly impact how advertisers create, grow, and manage their business. Your technical decisions will translate directly into advertiser success and the products customers discover on Amazon.

The Advertiser Controls team within Sponsored Products and Brands is building three critical platform capabilities. First, AI engineering infrastructure that powers our bidding and recommendation systems — systems for model fine-tuning, reinforcement learning, model inferencing, and preference optimization, with evaluation frameworks that ensure safety, reliability, and trust at scale. Second, agentic architectures that allow AI systems to work together seamlessly — agent-to-agent communication protocols for discovery, negotiation, and task handoff, lifecycle management for agent sessions, and state management that persists context across multi-step workflows. Third, experimentation systems that support multiple concurrent online experiments, accelerating the team's ability to test new bidding strategies and learn from real advertiser behavior. You'll work backwards from advertiser needs — collaborating with product managers, scientists, and engineers to understand business problems and translate them into technical solutions, seeking guidance from senior engineers and principals on complex architectural tradeoffs.

Key job responsibilities
- Design and develop agentic platform components using GenAI/ML technologies to deliver low-latency, secure advertiser experiences
- Build scalable systems that process millions of data points and optimize for cost efficiency through resource utilization, token consumption, and memory management
- Develop conversational AI and natural language interactions for advertiser bidding guidance
- Collaborate with cross-functional teams to integrate AI-driven solutions across the advertising ecosystem
- Identify and eliminate root causes of operational issues with permanent fixes; proactively improve team operations, tooling, and processes
- Write high-quality, maintainable code with clear documentation
- Provide meaningful code reviews, mentor engineers, and train new teammates on system architecture and operations
