  • Full-time

Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

Job Description

The Balance and Transfers team is at the forefront of Square’s push to provide first-party banking services to Square sellers. As a member of this full-stack sprint team you will develop key banking features like account and routing numbers, mobile check deposits, sub-accounts as well as novel features that leverage integrations with other parts of a seller’s business or are simply neglected by most banking competitors. We intend to provide our customers with powerful controls over their business’ cash flow that they have never had access to before. 

You will also be responsible for owning and evolving Square’s transfers business, which moves hundreds of millions of dollars a day on behalf of our sellers and is relied upon to infallibly get their money exactly where they need it when they need it, even if that means instantly.


When our sellers make a sale, the Business Banking team helps them manage and understand their business finances with products that include Square Card, Instant Transfers, account and routing numbers, advanced reporting, and cash flow insights. With this suite of products, we ensure that our customers get access to the funds they need when they need them, and that they can always understand and control where their money is going. We partner with platform and infrastructure teams to move billions of dollars each year on behalf of our sellers.

In this role, you’ll build and scale high-performance backend services, help power world-class front-end experiences within our web-based and mobile products, and contribute to the future of banking.

We are a product-focused engineering team with a full-stack background. Our projects leverage data-driven decisions to deliver features across mobile and web frontends.
