Staff Software Engineer, Web Payments

The Role
The Web Payment Experience team builds JavaScript SDKs and complementary UIs for developers who want to take payments with Square on their websites. Thousands of developers use our code to power the payments capabilities that millions of merchants depend on. We build the tools to make that not just possible, but also accessible. Just as front-end frameworks like React and Vue make it easier to build complex single-page apps, we're building frameworks to simplify the complexity of taking payments on the web.
