At Amazon Selection and Catalog Systems (ASCS), our mission is to power the online buying experience for customers worldwide so they can find, discover, and buy any product they want. We're solving a fundamental AI challenge: establishing product identity and relationships at unprecedented scale. Using Generative AI, Visual Language Models (VLMs), and multimodal reasoning, we determine what makes each product unique and how products relate to one another across Amazon's catalog. The scale is staggering: billions of products, petabytes of multimodal data, millions of sellers, dozens of languages, and infinite product diversity - from electronics to groceries to digital content. As an SDE II on the IRP team, you will take end-to-end ownership of significant features - from authoring design docs through coding, testing, deployment, and production operations. You'll work closely with Applied Scientists, Principal Engineers, and Product Managers on one of the most technically ambitious problems in e-commerce: building agentic diagnostics services that bring transparency and explainability to every change made across our catalog, backed by full data traceability. * Frontier AI in production: Work with GenAI, agentic frameworks, and large-scale information retrieval applied to billions of products - not in a research lab, but in production systems serving millions of customers daily. * Complexity scope: The CDA team owns one of Amazon's largest data lakes (hundreds of petabytes), serves 2,000+ internal customers, and processes catalog changes at 100K TPS. Your work will have real, visible impact from the start. * Build the agentic platform from the ground up: We are actively building our agentic diagnostics infrastructure now - you will help shape architecture decisions, not inherit a legacy system. * Clear growth trajectory: Strong SDE IIs grow toward ownership of agentic platform components, mentorship of L4s, and exposure to org-level design review and cross-team technical collaboration., * Own complete feature development end-to-end - from design doc through coding, testing, deployment, and operational excellence in production systems handling 100K+ TPS * Design and build agentic architectures that solve catalog change traceability, product identity, and relationship inference at billion-product scale using GenAI and LLM frameworks (e.g. LangGraph, Bedrock Agents) * Build and maintain production-grade data pipelines that process petabytes of multimodal catalog data with rigorous evaluation frameworks for agent accuracy, resilience, and close-loop feedback * Partner with Applied Scientists and Principal Engineers to translate research ideas and ambiguous business problems into scalable, maintainable engineering solutions * Drive technical design within your feature area - write well-reasoned design docs, lead code reviews, and set quality standards for your workstream * Contribute data-backed perspectives to the team's technical roadmap, tooling choices, and architecture patterns * Mentor engineers and new hires through code review, design discussions, and day-to-day guidance * Identify and close-loop on production reliability challenges at the intersection of GenAI accuracy, transactional system resilience, and large-scale information retrieval About the team Catalog Diagnostics and Analytics (CDA) team operates at a scale few engineering orgs reach: * ?️ Hundreds of petabytes across one of Amazon's largest internal data lakes * 100,000 TPS catalog change processing via a cost-effective micro-batch streaming architecture * ? 2,000+ internal customers relying on our datasets for daily business decisions * ? Agentic platform actively under construction - full-cycle feedback loops, agent accuracy evaluation frameworks, automated skill creation, and no-code testing and deployment lifecycle tooling We pioneer data management technologies and architecture patterns that set standards across the broader ASCS organization. Our team culture values technical rigor, psychological safety to experiment, and close collaboration with applied science and product partners. We move fast, write clean design docs, and take pride in systems that are both innovative and production scale. ## Related Videos - [ Evaluating AI models for code comprehension](https://www.wearedevelopers.com/videos/1462-evaluating-ai-models-for-code-comprehension) - [Fireside Chat with Werner Vogels, VP & CTO, Amazon.com & Daniel Gebler, CTO at Picnic](https://www.wearedevelopers.com/videos/1405-fireside-chat-with-werner-vogels-vp-cto-amazon-com-daniel-gebler-cto-at-picnic) - [Empowering Retail Through Applied Machine Learning](https://www.wearedevelopers.com/videos/976-empowering-retail-through-applied-machine-learning) - [Are Code Reviews Worth It?
