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 through Afterpay, 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. 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. Job Description The Global Account Management team is looking for a tenured account manager, consultant, or sales professional with experience managing high-value technical accounts to help retain and grow Square's presence in the Mid-Market space across Ireland. You will work with top C-level executives and technical leaders, finding creative ways to make Square's ecosystem work in complex, global organizations. You will identify ways to expand Square's reach with customers and act as an internal advocate for Square's highest-value clients. The ideal candidate will have worked in Mid-Market Account Management, business development, consulting, partnerships, sales or sales engineering and will be well-versed in working with and presenting to senior decision makers, including C-level executives, IT, finance and operations. They will have experience managing projects with multiple company partner
