Senior Android Engineer, Modes and Settings

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.

As Square has grown, we’ve continued to add features to support a diverse seller base. Our larger sellers often have different expectations and requirements than our smaller sellers, but Square takes the time to meet sellers where they are — making it feel like “it just works,” whether you’re a soap seller at a farmers market or operating the Chase Center, and everyone in between.

The Modes & Settings team strives to ensure that sellers of all sizes can configure their point of sale without being overwhelmed by complexity. The team builds a framework that enables feature teams to easily create configuration options for new features.
