iOS Engineer, Mobile Payment Experience

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've 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're building a significant, meaningful, and lasting business, and we are helping sellers worldwide do the same.
The Role
Mobile Payment Experience iOS builds SDKs for developers that build applications which take payments via Square - either talking to Square hardware via Mobile Payments SDK, storing a card in buyer facing applications via our In-App Payments SDK, or using Square Point of Sale via our app-switch API. We work closely with the Checkout Flow team, the Connected Device Experience team, and the Mobile Security team to create, package, and document the code that Square uses in our applications into ergonomic and simple SDKs that handle the complexities of taking card payments, so our developers can focus on running their business and serving their sellers.
As part of the Mobile Payment Experience iOS team, you'll be building SDKs that not only serve Square's products, but also independent and professionally developed applications that Square wouldn't build. You'll bring the same product quality focus from Square products to building developer tools and libraries that allow our customers to never miss a sale.
