Android Engineer, Square Square
San Francisco, CA

Job 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.

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