Job description
Description Amazon Music is awash in data! To help make sense of it all, the Data, Insights, Science and Optimization (DISCO) team enables repeatable, easy, in depth analysis of music customer behaviors. We reduce the cost in time and effort of analysis, data set building, model building, and user segmentation. Our goal is to empower our product teams at Amazon Music to make data driven decisions and effectively measure their results by providing high quality, high availability data, and democratized data access through self-service tools. If you love the challenges that come with big data then this role is for you. We collect billions of events a day, manage petabyte scale data on Redshift and S3, and develop data pipelines using Spark/Scala EMR, SQL based ETL, and Java services. You are a talented, seasoned, and detail-oriented Data Engineer who wants to take on big data challenges in an agile way. As a Data Engineer you should be an expert with data warehousing technical components (e.g. ETL, reporting solutions, data modelling), infrastructure (e.g. hardware and software) and their integration. Duties include designing events and signals, building big data pipelines, creating efficient data models, performing analysis, and statistical/ML modeling. This role requires you to focus on the data end to end, from producers to consumers. You will develop an understanding of our data, analytical techniques, and how to connect insights to the business, and you will gain practical experience in insisting on highest standards on operations in ETL and big data pipelines. With our Amazon Music Unlimited and Prime Music services, and our top music provider spot on the Alexa platform, providing high quality, high availability data to our internal customers is critical to our customer experiences. DISCO team develops data specifically for a set of key product domains like personalization and search. We deal in AWS technologies like Redshift, S3, EMR, EC2, DynamoDB, Kinesis Firehose, and Lambda. You'll build our data university and partner with Product, Marketing, BI, and ML teams to build new behavioral events, pipelines, datasets, models, and reporting to support their initiatives. You'll also continue to develop our offline analytics capabilities in Tableau and build out our real time reporting capabilities.
