Staff Software Engineer, Credit Underwriting — Remote

Posted 5 days ago

Since we opened our doors in 2009, the world of commerce has evolved immensely, and so has Square. After enabling anyone to take payments and never miss a sale, we saw sellers stymied by disparate, outmoded products and tools that wouldn\'t work together.

So we expanded into software and started building integrated, omnichannel solutions to help sellers sell online, manage inventory, offer buy now, pay later functionality, book appointments, engage loyal buyers, and hire and pay staff. Across it all, we have embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow in one place. Afterpay furthers our goal to provide omnichannel tools that unlock meaningful value and growth, enabling sellers to capture the next generation shopper, increase order sizes, and compete at a larger scale.

Today, we are a partner to sellers of all sizes – large, enterprise-scale businesses with complex operations, sellers just starting, as well as merchants who began selling with Square and have grown larger over time. As our sellers grow, so do our solutions. There is a massive opportunity in front of us. We are building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same.

Square Banking has revolutionized the way businesses and consumers obtain the funding needed to achieve their goals. Unlike traditional business financing products, Square Banking extends offers to pre-qualified sellers with no application process, funds are deposited as soon as the next business day, and repayment happens as a fixed percentage of daily card sales. Since the product launched in 2014, Square Banking has offered billions of dollars in loans to hundreds of thousands of sellers.
