Senior Android Engineer

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.

Square's Pricing team is a full-stack team creating technology that allows our merchants to bill the right amount for their products at the right time. We are developing new systems to offer sophisticated pricing and tax models to merchants of all types and scales in countries around the world. We are responsible for internal services, integrations with Square's payment technology, and customer facing features on both mobile and web. We're building a platform that is modular, highly available, scalable, secure and forward-looking.

We are looking for a talented individual to help build a delightful, performant, and reliable mobile platform that will be used by millions of merchants around the world to run core aspects of their business. If you are able to think modularly, want to create beautiful tools to empower small merchants, and are able to work on a sophisticated and complex mobile platform, the Pricing team may be for you.
