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

A number of product teams across Square are establishing a presence in our Toronto office and we're looking for foundational engineers to help us grow these teams from the ground up.  We value empathy, collaboration, and a commitment to delivering best-in-class software to the millions of sellers who rely on us, and we’ll look to you to anchor our culture in this dynamic new environment.  You’ll work closely with your colleagues in New York, San Francisco, Atlanta, and elsewhere as you build domain expertise on your local team, and will collaborate with cross-functional partners to establish effective processes.  As the team grows, you’ll help to onboard and provide continued mentorship for new engineers, and steward the architecture and quality of your products.
