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

We are taking a fresh look at this industry and building a modern product ecosystem that capitalizes on the themes of efficiency and automations – which are becoming the cornerstones of the new breed of hospitality tools. We’re addressing the needs of our seller customers in this dynamic landscape with iOS, Android, and Web-based software that integrates with our hardware, all backed by reliable services.

As a software engineer on the Seller team, you will help build products that clients use to run their businesses. 

You will:

  • Create beautiful, unique products which allow anyone to run a business

  • Envision new products and features that are inspired, considered, and magical
  • Partner collaboratively with experienced designers, product managers, and engineers; both on our team and with our friends on other teams


You have:

  • Natural curiosity and a desire to build beautiful intuitive products for our customers
  • Experience developing reliable, elegant apps and products
  • Designed apps with your teammates and with other teams and offices
  • Experience developing iOS applications
  • Experience shipping and improving products

Technologies we use and teach:

  • Swift and Objective-C
  • Core Data
  • Service APIs and Protocol Buffers
  • Hardware Integration
  • Metrics, monitoring, and alerting with a variety of internal and external tools 
  • And much, much more. Square is a great place to learn all kinds of technology!
