Software Engineer, Risk

  • Full-time

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

Effective risk management is the underpinning of Square’s business. It has enabled Square to offer a commerce platform to small businesses that traditional financial institutions deemed too risky.

One of our most important assets is trust --- as a seller, the ability to focus on running a business with the knowledge that Square has your back if things go wrong. Trust goes both ways; we also need to trust our sellers to run legitimate businesses that serve their customers. We protect our sellers against organized fraud rings, scammers, and other bad actors, while innovating by using data and technology that enables more good customers.

The Risk Data Systems teams is responsible for building the data tools that power all of Risk’s automated decisioning and statistical modeling.
