Senior Software Engineer , Payroll

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.

When we launched the little white reader, we invented mobile, ubiquitous payments and enabled anyone to start, run, and grow a business. Ten years and billions of transactions later we're re-imagining commerce for businesses of all types and sizes—we're helping the independent electrician send invoices, helping the beauty salon pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. 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.

Much in the same way that Square revolutionized payments, we want to radically alter how employees get paid and businesses manage their finances. Our mission is to make running a business simple and personal by applying automation and an excellent user-experience. Our small collaborative team has already built many foundational features and are now focused on improving and experimenting beyond a traditional payroll product. We want to transform the lives of people that make their living through our platform. We're a growing part of the Square ecosystem and are using our position to build products and features that are beyond the capabilities of our competitors.

We are an expanding team with an abundance of growth and influence opportunities. We are building the best full featured payroll solution for small businesses with an emphasis on design and automation. At the same time we are doing this in an organized and scalable way, making smart choices about how to automate important functions.
