Job Description

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 innovate on behalf of our customers to ensure uniqueness and consistency of product identity and to infer relationships between products in Amazon Catalog to drive the selection gateway for the search and browse experiences on the website. 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.

The research challenges are immense. GenAI and VLMs hold transformative promise for catalog understanding, but we operate where traditional methods fail: ambiguous problem spaces, incomplete and noisy data, inherent uncertainty, reasoning across both images and textual data, and explaining decisions at scale. Establishing product identities and groupings requires sophisticated models that reason across text, images, and structured data—while maintaining accuracy and trust for high-stakes business decisions affecting millions of customers daily.

Amazon's Item and Relationship Platform group is looking for an innovative and customer-focused applied scientist to help us make the world's best product catalog even better. In this role, you will partner with technology and business leaders to build new state-of-the-art algorithms, models, and services to infer product-to-product relationships that matter to our customers. You will pioneer advanced GenAI solutions that power next-generation agentic shopping experiences, working in a collaborative environment where you can experiment with massive data from the world's largest product catalog, tackle problems at the frontier of AI research, rapidly implement and deploy your algorithmic ideas at scale, across millions of customers.

Key job responsibilities
Key job responsibilities include:
* Formulate novel research problems at the intersection of GenAI, multimodal learning, and large-scale information retrieval—translating ambiguous business challenges into tractable scientific frameworks
* Design and implement leading models leveraging VLMs, foundation models, and agentic architectures to solve product identity, relationship inference, and catalog understanding at billion-product scale
* Pioneer explainable AI methodologies that balance model performance with scalability requirements for production systems impacting millions of daily customer decisions
* Own end-to-end ML pipelines from research ideation to production deployment—processing petabytes of multimodal data with rigorous evaluation frameworks
* Define research roadmaps aligned with business priorities, balancing foundational research with incremental product improvements
* Mentor peer scientists and engineers on advanced ML techniques, experimental design, and scientific rigor—building organizational capability in GenAI and multimodal AI
* Represent the team in the broader science community—publishing findings, delivering tech talks, and staying at the forefront of GenAI, VLM, and agentic system research

Basic Qualifications

- PhD, or Master's degree and 4+ years of CS, CE, ML or related field experience
- Experience programming in Java, C++, Python or related language
- 2+ years of building machine learning models or developing algorithms for business application experience

Preferred Qualifications

- Prior experience in the domains of LLMs, foundation models, or large-scale deep learning systems
- Publications in top-tier venues such as NeurIPS, ICML, ICLR, CVPR, ICCV, EMNLP, ACL, NAACL, COLING, KDD, SIGMOD, WWW, AAAI, or similar
- Experience with Visual Language Models (VLMs), multimodal transformers, or vision-language pretraining
- Experience with explainable AI, model interpretability, or uncertainty quantification
- Strong experimental design skills and statistical analysis expertise
- Hands-on experience with Generative AI, including prompt engineering, fine-tuning, RLHF, or agentic architectures
- Track record of deploying ML models at scale in production environments processing billions of data points
- Excellent written, verbal communication & data presentation skills.

Company Information

Company Name: Amazon.com Services LLC

Company Website: https://www.amazon.com

Company Address: 410 Terry Ave N, Seattle, WA 98109, United States

Amazon.com Services LLC is an operating company in the Amazon corporate family that supports and delivers a broad set of technology-enabled retail and marketplace services. As part of the larger Amazon organization, it participates in the operation and management of Amazon’s online retail marketplace, third‑party seller programs, fulfillment and logistics solutions, and related customer-facing services. The company’s activities are oriented around applying software, systems engineering and logistical infrastructure to enable large-scale e-commerce, digital distribution and platform services for consumers and businesses. Overview and scope Amazon.com Services LLC functions as one of the entities through which Amazon delivers commerce and seller-related services. In practice, that includes enabling Amazon’s marketplace for third‑party sellers, operating fulfillment programs (including Fulfillment by Amazon—FBA), and supporting the web and mobile retail experiences that customers use to discover, buy and receive products. The company leverages Amazon’s broader investments in distributed computing, data analytics, inventory systems and automated fulfillment to provide both consumer-facing retail and business-to-business seller services. Core business activities The core activities associated with Amazon.com Services LLC revolve around online retail operations and the technology and logistics that underpin them. Key activities include: operating the Amazon.com consumer marketplace and associated storefronts; managing programs that onboard, list and transact for third‑party sellers; providing fulfillment, warehousing and shipping services for inventory enrolled in Amazon’s logistics networks; powering payments and order processing systems; and supporting customer service operations related to retail transactions. These activities are tightly integrated with Amazon’s global logistics network, delivery services, and software platforms that enable inventory management, pricing, content management and search/recommendation systems. Main products and services While Amazon.com Services LLC is one of several operating companies in the Amazon group, the practical products and services associated with its operations include marketplace hosting for third‑party sellers (seller accounts, tools and dashboards), fulfillment and warehousing services (including FBA), order processing and returns management, customer service support for retail transactions, and technology platforms that expose APIs and seller tools for listing, pricing and inventory control. These services enable merchants to sell through Amazon’s digital storefronts and to use Amazon’s fulfillment infrastructure for storage, packing and shipping. Relationship to broader Amazon offerings The operational scope of Amazon.com Services LLC overlaps and integrates with other Amazon businesses and technology platforms. For example, Amazon Web Services (AWS) provides the cloud infrastructure and many platform services that power Amazon’s retail site and seller services, while Amazon’s consumer-facing subscription services such as Amazon Prime (which bundles fast shipping, streaming and other benefits) influence demand and fulfillment priorities. Additionally, Amazon’s devices (Kindle, Echo/Alexa, Fire TV) and digital content offerings (Prime Video, Amazon Music, Audible) form adjacent product lines that operate within the same corporate ecosystem, increasing cross‑channel customer engagement with the retail marketplace. Technology and innovation focus Amazon.com Services LLC operates in an environment driven by software, systems engineering and logistics innovation. Amazon’s public communications emphasize technology investments in automation, robotics, machine learning, search and recommendation algorithms, and large-scale distributed systems to improve selection, convenience and price. The company’s approach to improving customer experience and seller services is built on continuous iteration in software, data science and operational research, as well as deployment of warehouse automation and transportation optimization technologies. Customers and users End customers are the millions of consumers who shop on Amazon’s retail websites and use related mobile apps. Another primary customer segment is the millions of third‑party sellers and professional merchants who use Amazon’s marketplace and seller services to reach consumers globally. Businesses and developers that integrate with Amazon’s seller APIs, fulfillment services, and advertising platforms also rely on the services and systems that Amazon.com Services LLC helps deliver. Official mission and corporate context Amazon’s public materials state a mission and guiding principle focused on customer centricity—commonly expressed by the company as striving “to be Earth’s most customer‑centric company.” That mission underpins the retail and marketplace operations and is reflected in investments in selection, convenience and low prices. Amazon operates across multiple industries including e-commerce, cloud computing, digital streaming, consumer electronics and logistics; Amazon.com Services LLC is a part of that broader corporate structure and concentrates on the commerce and seller-facing components of the business. Regulatory and corporate form Amazon.com Services LLC is a limited liability company within the Amazon corporate structure; like other operating subsidiaries, it is used to carry out specific aspects of Amazon’s commercial activities. Public filings and corporate disclosures identify multiple Amazon subsidiaries that collectively operate global retail, subscription, cloud and device businesses. Amazon’s public investor relations and corporate governance materials describe Amazon as a technology company with e-commerce and cloud computing core competencies, and Amazon.com Services LLC functions within that legal and operational framework. Summary In summary, Amazon.com Services LLC is a technology-enabled operating company in the Amazon family that provides and supports the marketplace, seller services, fulfillment and related retail operations that allow consumers to buy products and third‑party sellers to reach customers through Amazon’s digital storefronts. Its work is characterized by large-scale software systems, fulfillment and logistics networks, and continual investment in automation and data-driven tools to improve customer and seller experiences. The company’s activities align with Amazon’s stated customer-centric mission and the broader corporate focus on leveraging technology to scale commerce and distribution globally.
