Job Description

Description
Amazon's Sponsored Products and Brands division is building the next generation of AI-powered bidding systems that help millions of advertisers optimize their campaigns. We're looking for a Software Development Engineer II to join our Agentic Bidding Platform team, where you'll design and build the bidding controls and recommendations that directly impact how advertisers create, optimize, and grow their business on Amazon.
In this role, you'll own the development of three critical platform capabilities. First, you will build the AI engineering infrastructure that enables our bidding systems-developing systems for model fine-tuning, reinforcement learning, and preference optimization, while creating evaluation frameworks that ensure safety, reliability, and trust at scale. Second, you will interface agentic architectures that allow AI systems to work together seamlessly, including agent-to-agent communication protocols for discovery, negotiation, and task handoff, lifecycle management for agent sessions, and state management frameworks that persist context across multi-step workflows. Third, you will design and build experimentation systems that support multiple concurrent online experiments, accelerating our team's ability to test new bidding strategies and learn from real advertiser behavior.
As an SDE2, you'll work as an autonomous contributor. You will work backwards from advertiser needs-collaborating with product managers, scientists, and other engineers to understand business problems, then translating those into technical solutions. While you'll make independent decisions on implementation, you'll seek guidance from senior engineers and principals when facing complex architectural tradeoffs or ambiguous technical challenges where the business problem is clear but the path forward requires exploration.
The work you do will have direct, visible impact. Your infrastructure will power the AI systems that help a small business owner optimize their first campaign and enable enterprise brands to manage millions in ad spend. You'll be building customer-facing products where your technical decisions translate directly into advertiser success and the products customers discover on Amazon.
Key job responsibilities

• Design and develop the Agentic Bidding platform using Gen AI/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

A day in the life
As a Software Engineer on the Agentic Bidding Platform team you will be filled with collaborative problem-solving, innovative technology development, and strategic thinking. You'll work alongside expert applied scientists, software engineers and product managers, exploring creative solutions to complex advertising challenges and developing sophisticated machine learning and AI models that transform how advertisers connect with shoppers.
