Since we first opened our doors in 2009, the world of commerce has evolved immensely – and so has Square. After enabling anyone to take a payment 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, run a busy kitchen, book appointments, engage loyal buyers, and hire and pay staff. And 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 all in one place. 

Today, we’re a partner to sellers of all sizes – large, enterprise-scale businesses with complex commerce operations, sellers just starting out, as well as merchants who began selling with Square and have grown larger over time. Whether it’s the food truck that’s establishing a brick & mortar restaurant, the former sole proprietor adding her first employees, or the entrepreneur expanding from one location to ten, as our sellers scale, so do our solutions. We all grow together.

As a member of the Square Conversations Data Science team, you will use statistical, machine learning, analytics, and data engineering techniques to empower decision-making for Square’s core messaging product. Over the last two years, the Conversations team has built an impressive communication platform that is used by a large and diverse set of sellers, in turn delivering tremendous business value (e.g. enablement of buyer-seller interactions through text and email, invoices/receipt messages, automated reminders, etc.). As the team continues to scale, there will be numerous opportunities for data science to generate additional impact, such as sizing new strategic opportunities related to integrations with the rest of the Square ecosystem, operationalizing new metrics, evaluating the incremental impact of new launches, leveraging machine learning to carry out segmentation/generate predictive insights, and collaborating with other orgs across Square on new initiatives.
