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

Retailers have struggled too long with clunky, outdated and disconnected tools. While mammoth Retail and E-tail forces are looking to disrupt smaller merchants, we are empowering those merchants with simple and elegant solutions to complex problems,  like predictive analytics and fluid, omni-channel capabilities to meet the customer wherever they are - to always make the sale. Based in New York City, we are one of the newest launched products at Square. We are a lean team, benefitting from the resources of the larger organization while having lots of room to focus and innovate.

  • Embed with partner teams to extend Square's platform for the benefit of retail sellers;
  • Deliver features to our growing base of subscribers, shipped at a rapid cadence; and
  • Empower our sellers with the tools they need to compete with the biggest retailers.


You have:

  • 2+ years of full-stack development experience, including web applications, and an excellent command of engineering fundamentals
  • Openness to continuing to grow your breadth and depth, including iOS/Android 
  • Unwavering commitment to customer experience and product quality
