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 smartphone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Terminal, Square Appointments, Square Online Store, 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.

Square's mobile applications continue to scale and diversify as each new opportunity is tackled by teams of passionate engineers. App Platform endeavors to amplify the efficiency of developing, building, testing, and releasing high-quality mobile apps. Within App Platform, opportunities exist on teams handling specific aspects of our overall mission. Come join our Mobile Performance and Services team which focuses on building services and frameworks for connecting mobile applications to Square's backend services.
