We believe in the everyday hero.
Small business owners are at the heart of all we do, so we're creating tools that help them run their business. With a founders mentality and a 'team-first attitude' our diverse teams across Europe, South America, and the United States work together to ensure that the small business owners we partner with can be successful in doing what they love.
The Merchant Growth Tribe’s mission is to build an ecosystem of simple but powerful products and services to help SumUp’s 1.5m+ global merchants grow their businesses. In addition to our core product, the Point-of-Sale (POS) application, the Tribe also develops invoicing and ecommerce services.
Beyond this, we aim to expand SumUp’s product range to cover areas like accounting, marketing, customer loyalty and business analytics. Ultimately, our work strengthens SumUp’s ability to serve the needs of merchants around the world.
As a Frontend Engineer, you'll work with a small cross-functional team to build tools that help small businesses thrive. By shipping code early and often, you'll see the impact of your work on merchants’ lives right away. You'll collaborate with experts in product, design and operations to deliver mission-critical features that power the SumUp ecosystem.
