About Square

Job Description

We believe the economy is better when everyone has access. When everyone has room to grow. No one should be left out because the cost is too great or the technology too complex. We started with a little white credit card reader but haven't stopped there. We're empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. We're here to help sellers of all sizes start, run, and grow their business-and helping them grow their business is good business for everyone.

Payments is Square's core product and the foundation for the growth of many other Square products. Millions of merchants use Square payments as part of their business every day. Terminal for Business ensures that sellers of all sizes and types can use Square as quickly and easily as possible. Square has done a great job building remarkable experiences for individuals and small businesses. We are working on the next generation of payment experiences for larger businesses, fundamentally changing how Square works.
