Since we first opened our doors in 2009, the world of commerce has evolved immensely – and so has Square. After enabling anyone to take a payment 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, run a busy kitchen, book appointments, engage loyal buyers, and hire and pay staff. And across it all, we’ve embedded financial services tools at the point of sale, so merchants can access a business loan and manage their cash flow all in one place.

Today, we’re a partner to sellers of all sizes – large, enterprise-scale businesses with complex commerce operations, sellers just starting out, as well as merchants who began selling with Square and have grown larger over time. As our sellers scale, so do our solutions. We all grow together.

There is a massive opportunity in front of us. We’re building a business that is big, meaningful, and lasting. And we are helping sellers around the world do the same.

The API Frameworks team creates tools that empower our internal developers to rapidly release new internal and public APIs and features. We are a small dedicated, and growing team with an abundance of growth and impact opportunities.

As a software engineer on the API Frameworks team, you will oversee the design, creation, and maintenance of centralized, scalable, and performant libraries and services used by every Square internal and public API. You'll care about performance, down to the millisecond, and know how to not only implement, but maintain these systems. Every call from an external developer who integrates with Square will directly use the code you've helped develop.

You will have the opportunity to participate in the community of internal developers who enable the Square Developer Platform and use that knowledge to create new offerings and adapt existing ones to meet the needs of our developers. Lastly, you'll have fun working on new complex problems with skilled engineers who are passionate about what they do.

You Will: 

• Build highly performant systems that can handle millions of requests per day to enable all of Square's third-party developers.
• Work with our product teams, *many* other engineering teams, and partner developers to design Squares global developer platform.
• Build systems that maintain customers' sensitive data and hold Square to the highest standards for security and compliance.
• Design fault tolerant systems so the team can be brave, move fast, and break things, without ever showing a negative impact to customers.
