Senior iOS Engineer, Neighborhoods

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 Launched in October 2025, Neighborhoods is a new network between Cash App and Square that gives local businesses the ability to offer online ordering with the power of a mobile app. Sellers get their own branded storefront, accessible on both web and inside Cash App. Customers can seamlessly order ahead, reorder, earn rewards and stay connected to support the businesses they love. With 4 million sellers using Square and 57 million monthly active accounts on Cash App, we have a unique opportunity to connect local sellers and local customers in their area.
