Senior Android Engineer, Personalization

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.

The Personalization team for Square Point of Sale is building out the next generation of Square by introducing the Add Ons ecosystem for Point of Sale.  With this ecosystem, we are empowering merchants to tailor their point of sale to the needs of their business, as well as creating a foundation for third party developers to incorporate unique value propositions into Point of Sale easily and securely.  This level of personalization will allow us to scale the Point of Sale application to a wide variety of businesses, and unlock powerful new tools for our merchants.
