An information-rich and accurate product catalog is a strategic asset for Amazon. It powers unrivaled product discovery, informs customer buying decisions, offers a large selection, and positions Amazon as the first stop for shopping online. We use data analysis and statistical and machine learning techniques to proactively identify relationships between products within the Amazon product catalog. This problem is challenging due to sheer scale (billions of products in the catalog), diversity (products ranging from electronics to groceries to instant video across multiple languages) and multitude of input sources (millions of sellers contributing product data with different quality). Amazons Item Authority group is looking for an innovative and customer-focused senior research scientist to help us make the worlds best product catalog even better. We believe that failure and innovation are inseparable twins. 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 work in a collaborative environment where you can experiment with massive data from the worlds largest product catalog, work on challenging problems, quickly implement and deploy your algorithmic ideas at scale, understand whether they succeed via statistically relevant experiments across millions of customers. Position Responsibilities: Map business requirements and customer needs to a scientific problem. Align the research direction to business requirements and make the right judgments on research/development schedule and prioritization. Research, design and implement scalable machine learning (ML), natural language, or computational models to solve problems that matter to our customers in an iterative fashion. Mentor and develop junior research scientists and developers who work on data science problems in the same organization Stay informed on the latest machine learning, natural language and/or artificial intelligence trends and make presentations to the larger engineering and research science communities.
