Square 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.

Risk Engineering works to protect Square and our customers from fraud and payment disputes. We keep our customers safe while tens of billions of dollars flow through Square annually. To do this, we build systems to detect and respond to potential fraud threats, provide outstanding tools to agents for investigating fraud events, and give our customers seamless web and mobile experiences to manage and fight payment disputes. Our mission is to protect Square, protect our customers, and make a complicated and sometimes painful process understandable to all.
