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.
As a software engineer on the Payments team, you will be responsible for designing, building, and maintaining the Payments Platform services and infrastructure that move money for Square. You will be deeply involved in the technical details of building highly available and reliable services, while also working with product teams to enable Square to rapidly build new capabilities for our merchants and buyers all over the world.
