Our Purchase squad owns the end-to-end checkout and buying experience across SumUp's platforms, from self-service journeys to sales-assisted flows, covering everything from hardware and subscriptions to bundled offers and promotions. We're in an active phase of stabilising and scaling our commerce platform, reducing complexity, and building the foundations that allow us to move faster and serve merchants better across multiple markets. This is a backend-leaning full stack role where you'll work on real, impactful problems that sit right at the centre of how merchants discover, buy, and manage SumUp's products.

* Help improve platform reliability and reduce technical complexity, addressing recurring issues and supporting ongoing migrations
* Work closely with product managers, designers, and engineers to deliver scalable, high-quality features across multiple markets
* Improve merchant-facing experiences, including better visibility into orders, invoices, and tracking information
You'll be great for this role if
* Solid experience building full stack applications, with a backend focus. Ideally comfortable with Node.js or Go, though we're open to other backend languages.

* Strong communication skills in English, both written and spoken, with the ability to give and receive clear, constructive feedback.
