(Android) Senior Software Engineer, Square for Retail

  • Atlanta, GA, USA
  • Employees can work remotely
  • Full-time
  • Alternate Location: Toronto, Canada

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

Retailers have struggled too long with clunky, outdated and disconnected tools. Even as mammoth Retail and e-commerce forces threaten smaller merchants, we are empowering those merchants with simple solutions to complex problems - like predictive analytics and fluid, omni-channel capabilities to meet customers wherever they are - to always make the sale. 

Square for Retail is a growing product team based in New York, San Francisco, Toronto, and Atlanta. We benefit from (and contribute to) the resources of the larger organization while solving Retail-specific challenges. We are enthusiastically customer focused, and iterate quickly using a build-measure-learn approach.  

You will:

  • Use your extensive expertise in Android development to lead a small group of Android engineers building solutions together that meet our sellers’ challenges.
  • Develop for our custom, purpose-built hardware - Square Register - with dual displays;
  • Be a part of creating a product that brings superpowers to sellers.
  • Build and test client software with complex server, network and hardware interactions;
  • Craft pixel-perfect, intuitive UI that delights our sellers with its ease of use;
  • Work with a world-class team of experienced and dedicated engineers, product managers and designers;
  • Deliver features to our growing base of subscribers, shipped at a rapid cadence
  • Work collaboratively with product managers and designers to define and establish product scope and design.


  • 5+ years of Android development experience, and an excellent command of engineering fundamentals
  • Mentor a group of software engineers to deliver solutions while fostering growth.
  • Unwavering commitment to customer experience and the quality of your work.
  • An eagerness to share your ideas, and openness to those of others.
  • Empathy for your customers and colleagues.
  • Desire to build beautiful and refined products 

Technologies we use and teach:

  • Kotlin for development
  • Application architecture based on Square’s modern open source library, Workflow
