Software Quality Engineer

  • San Francisco, CA
  • Full-time

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

Our hardware team builds the tangible connection to all that is Square. We started with a simple and elegant Reader that turns any phone or tablet into a mobile point of sale. Since then, we have expanded our hardware footprint to meet the needs of more sellers. Most recently, we introduced our first Android-based solutions: Square Register, the first integrated point of sale that enables people to start selling right out of the box, and Square Terminal, the all-in-one device for payments and receipts. In this role, you will ensure our sellers and their customers have a remarkable experience by shaping our device software validation strategy for our Square hardware products.
