Company Description

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.

Job Description

The App Marketplace team builds products that are central to Square's platform approach to e-commerce. We connect the thousands of developers building on Square's Public API to the millions of Square sellers who need tools to run their small businesses.

We need your help to connect our sellers to the thousands of products being built on Square's platform. As a software engineer on the team, you will own the design, implementation and maintenance of systems which identify the best app for each seller.
