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.

Data Security is core to Square's success. Square strives to make the basics of running a business easy for our sellers so that they can instead focus on building and growing their business. The Data Security Engineering team similarly aims to make it easy for our engineering teams to protect sensitive data throughout its lifecycle so that Square can ship remarkable products. We achieve these goals through developing data security education and policies, preventative guardrails, and secure, convenient tooling.
