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 Square is looking for a team-oriented Account Executive that's excited to grow with us and make an impact on our UK business. This role provides the opportunity for you to refine your sales acumen, collaborate with your direct team and cross-functional teams, and work closely with hundreds of inspiring entrepreneurs and business owners. Through your extraordinary communication skills, you will connect with customers to sell the value of Square to their business - quickly establishing trust and successfully building upon your relationships throughout the sales process. You're a great fit for this role if you've got an entrepreneurial spirit, a growth-oriented mindset and an innate knack for collaborative p

About the Team Our ambition for DashMart Fulfillment Services (DFS) is to power the best grocery experience, letting customers shop their full list 24/7 from their favorite merchant, with error-free same-day delivery at in-store prices. Carrying the right items across an extensive merchant selection is foundational to our infrastructure and consumer offering. This team owns both of those inputs end to end ensuring that we choose the right items, they arrive in the right quantities and on time and are fully in sync with our warehouse operations to make them available to consumers. About the Role We're looking to bring on a few Senior Managers with strong operational and analytical backgrounds that can tackle our most critical and ambiguous problems and build durable solutions at scale that will empower the long-term success of DFS. These roles require a holistic understanding of how we think through merchant selection & partnerships to how we build our fulfillment model. These aren’t insights roles - you will be expected to own root cause diagnostics, how to test operationally, and how to scale initiatives through productized solutions in partnership with product, engineering and local operations. One role will focus on merchant selection and one roles will focus on inventory health - both are critical to the end to end success of a DFS partnership. A few of the problems you might own: Merchant Selection. Identify where to play and how to win from knowing what merchants our customers want, to where we should launch those as a test and determine what success looks like to scale. In-Stock. Own availability across forecasting, replenishment, receiving and labor planning. Find the binding constraint and decide what service level is worth paying for, by category. Catalog. The catalog is the promise we make before the order. Every error shows up later as a missing item, a wrong order or lost margin. Shrink. Shrink is the cost of the in-stock promise. Separate what ops
