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.

The Communications Platform team builds the platform that delivers hundreds of millions of messages per month to Square merchants and customers. Our main mission is to make communication between Square and its customers scalable, easy, effective, and intelligent.

We enable multi-channel (email, sms, push, in-product) real-time messaging through well defined APIs.

We are a small, focused, and rapidly growing team with an abundance of growth and impact opportunities.
