Today, catalog data defects create fulfillment challenges that drive hundreds of millions of dollars in operational costs and limit our ability to grow selection. Are you passionate about building software systems that operate at massive scale on the largest catalog on earth? We are seeking a Senior Software Development Engineer to lead the design, implementation, and delivery of systems that ingest high-fidelity physical product observations (images, OCR text, barcodes, dimensions, expiration) for millions of inventory units flowing daily through Fulfillment Centers, then leverage that data to improve catalog data quality. This initiative impacts multiple programs visible to Amazon senior leadership, reduces operational costs for Sellers and Fulfillment Centers, and drives revenue growth through expanded selection.\nKey job responsibilities\nLead architecture of large-scale distributed systems that process hundreds of millions of transactions daily, owning design, implementation, and operation across the full software lifecycle.\nPartner with Applied Scientists to translate ML research into production inference infrastructure that extracts product information from images at scale.\nDefine a multi-year technical roadmap, sequence delivery to balance near-term customer impact with long-term platform investment, and drive architectural consistency across engineering and science workstreams by influencing teams you depend on but do not directly control.\nEstablish measurable quality, reliability, scalability, and cost-efficiency standards so systems continue to perform as expected while scale grows.\nMentor engineers through hands-on code reviews, design reviews, and technical guidance. Influence product technical direction by articulating architectural trade-offs, tech debt, and their business impact to stakeholders and partners.\nA day in the life\nYou might start the morning reviewing operational dashboards for your team's ingestion pipelines, then jump into a design review where you help engineers evaluate trade-offs for a new image-processing service. After lunch you pair with an Applied Scientist to prototype an integration between a new ML model and your production inference stack. Later, you draft a technical document outlining your recommended approach for an upcoming cross-team migration, preparing to align stakeholders across catalog and fulfillment systems. Your work balances hands-on coding with strategic guidance, keeping the team focused on delivering reliable, high-quality systems.\nAbout the team\nAmazon Selection and Catalog Systems (ASCS) builds and operates the world's largest e-commerce product catalog. We are the primary source for product, relationship, and offer data, and the accuracy of our catalog is foundational to everything Amazon does, from the detail page a customer sees to the fulfillment center that ships their order. We support hundreds of internal clients and businesses that contribute to the Amazon catalog.\nOur team values inclusivity, transparency, and customer-centric problem solving. We continuously invest in scalable mechanisms, software systems, Generative AI models, and agentic workflows to sustainably meet evolving business demand. If you are excited about shaping technical strategy at catalog scale, this is the place to do it.\nBasic qualifications\n- 5+ years of non-internship professional software development experience\n- 5+ years of programming with at least one software programming language experience\n- 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience\n- Experience as a mentor, tech lead or leading an engineering team\nPreferred qualifications\n- 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience\n- Bachelor's degree in computer science or equivalent\nAmazon is an equal opportunity employer and does not discriminate on the basis of protected veteran status, disability, or other legally protected status.\nOur inclusive culture empowers Amazonians to deliver the best results for our customers.
