DESCRIPTION
Job summaryThe AI Data Team in Amazon Web Services (AWS) is looking for a Data Scientist with a passion for developing innovative methods to maximize the power of natural language data. This position is an opportunity to apply your expertise in a challenging but supportive environment. The position may be remote, with a preference for Santa Clara, Seattle, or New York City. We work in distributed teams, and strengthen our connections by traveling approximately five days per quarter for in person meetingsThe mission of the AI Data Team is to engineer the datasets critical to the success of AWS’s machine learning services. From chatbots to subtitles to search results and beyond, these products support dozens of languages and impact millions of people every day. We are a group of language engineers, linguists, data scientists, data engineers, and program managers, and we partner closely with the science, engineering, and product teams. We are customer obsessed and committed to delivering results with the highest quality and integrity.As a Data Scientist, you will start by learning the full context of critical projects for Lex, a conversational AI service used for building chatbots, consulting with stakeholders in science, engineering, and product teams. You will determine the appropriate metrics for data analysis and quality checks on data annotations, to ensure that the data is optimized for developing models that exceed customer expectations. You will consider domain gaps, data bias, and data noise in your analysis. You will design and write Python packages for these processes, and work with data engineering to implement them in data pipelines built to scale.You will also work with language engineers to understand the challenges we face in producing or acquiring data, and in generating high quality labels.
