Senior iOS Engineer

  • San Francisco, CA, USA
  • Full-time
  • Current Square Employee?: Apply via go/jobs

Company Description

We believe everyone should be able to participate and thrive in the economy. So we’re building tools that make commerce easier and more accessible to all. We started with a little white credit card reader but haven’t stopped there. Our new reader helps our sellers accept chip cards and NFC payments, and our Cash app lets people pay each other back instantly. We’re empowering the independent electrician to send invoices, setting up the favorite food truck with a delivery option, helping the ice cream shop pay its employees, and giving the burgeoning coffee chain capital for a second, third, and fourth location. Let’s shorten the distance between having an idea and making a living from it. We’re here to help sellers of all sizes start, run, and grow their business—and helping them grow their business is good business for everyone.

Job Description

Come join one of our many growing iOS Teams! Each has it's own unique opportunity to help grow our business and make a positive impact on our merchants and sellers!

Teams that are currently hiring:

Point of Sale - https://squareup.com/us/en/software/point-of-sale

Team Management - https://squareup.com/us/en/point-of-sale/features/team-management

Application Platform Mobile - The work on this team will be more internal platform focused and the challenges are going to be different from the standard feature/product work. For example, our Point of Sale app contains more than a million lines of code and so mobile development at this scale is highly complex and a largely unsolved problem in the industry.
