Job Description

As part of the AWS Solutions organization, we have a vision to provide business applications, leveraging Amazon’s unique experience and expertise, that are used by millions of companies worldwide to manage day-to-day operations. We will accomplish this by accelerating our customers’ businesses through delivery of intuitive and differentiated technology solutions that solve enduring business challenges. We blend vision with curiosity and Amazon’s real-world experience to build opinionated, turnkey solutions. Where customers prefer to buy over build, we become their trusted partner with solutions that are no-brainers to buy and easy to use.

The Team

Just Walk Out (JWO) is a new kind of store with no lines and no checkout—you just grab and go! Customers simply use the Amazon Go app to enter the store, take what they want from our selection of fresh, delicious meals and grocery essentials, and go!

Our checkout-free shopping experience is made possible by our Just Walk Out Technology, which automatically detects when products are taken from or returned to the shelves and keeps track of them in a virtual cart. When you’re done shopping, you can just leave the store. Shortly after, we’ll charge your account and send you a receipt. Check it out at amazon.com/go. Designed and custom-built by Amazonians, our Just Walk Out Technology uses a variety of technologies including computer vision, sensor fusion, and advanced machine learning. Innovation is part of our DNA! Our goal is to be Earths’ most customer centric company and we are just getting started. We need people who want to join an ambitious program that continues to push the state of the art in computer vision, machine learning, distributed systems and hardware design.


Key job responsibilities
Everyone on the team needs to be entrepreneurial, wear many hats and work in a highly collaborative environment that’s more startup than big company. We’ll need to tackle problems that span a variety of domains: computer vision, image recognition, machine learning, real-time and distributed systems.

As a Sr. Applied Scientist, you will help solve a variety of technical challenges and mentor other scientists. You will be the thought leader of the team. You will tackle challenging, novel situations every day and given the size of this initiative, you’ll have the opportunity to work with multiple technical teams at Amazon in different locations. You should be comfortable with a degree of ambiguity that’s higher than most projects and relish the idea of solving problems that, frankly, haven’t been solved at scale before - anywhere. Along the way, we guarantee that you’ll learn a ton, have fun and make a positive impact on millions of people.

Key job responsibilities
- Develop a novel framework and advance the theory and practice of multi-object tracking, re-identification, person activity understanding, multi-modal foundation model, and generic video understanding
- Create innovative techniques for efficient visual processing that can scale to real-world applications
- Investigate approaches to reduce the computational and data requirements of visual AI systems

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.
