Description

Company DescriptionSquare builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We're working to find new and better ways to help businesses succeed on their own terms-and we're looking for people like you to help shape tomorrow at Square.Job DescriptionSquare's ML Platform group has one goal: make machine learning at Square easy. Square has over 100 engineers and data scientists building machine learning solutions, and our group's job is to support these efforts. We build model development tools, feature computation infrastructure, and high scale serving systems to ensure that those trying to use machine learning can spend less time on infrastructure and more time delivering value.Within that group, the Data Intelligence team provides systems and tools that help teams transform their data into reusable knowledge, so that new ML systems start with access to a large set of observations and features. To accomplish these goals, we own the services that compute real-time features used in the decision flows of all payments at Square and the historical data store that allows models to be trained. Our systems have to be tough enough to handle the processing load of all payments at Square, while also being flexible enough to help data scientists from many teams to do their job.We sit in a unique spot as a platform team since we work with data scientists, engineers, and product managers from across the organization.
