At SumUp, we create tools that help small businesses get paid easily, manage money confidently, and grow sustainably. Our mission is to empower merchants around the world, and at the heart of that mission is a robust, scalable Payments Platform developed in Sofia.
We’re now expanding this platform with a new dedicated Pricing team – and we’re looking for Software Engineers (Mid & Senior) who want to build core services from the ground up and make a lasting impact across SumUp.
ABOUT THE TEAM
Pricing is an important part of any payments business. The Pricing team will build and own the services that determine how SumUp’s products and transactions are priced worldwide. This includes maintaining existing pricing tools and creating a future-ready pricing platform that enables precision, flexibility, and transparency.
We’ll be a small, high-impact team with strong engineering ownership. You’ll help define how pricing logic is modeled, how it evolves, and how it's applied at scale for millions of transactions across our ecosystem.
ABOUT THE ROLE
As a Senior Software Engineer in our Pricing team, you’ll help design, build, and maintain a scalable and compliant pricing platform for SumUp’s payment ecosystem. You’ll participate in architectural discussions, guide technical decisions, and deliver projects independently or in collaboration with your squad.
Your work will directly shape how SumUp evolves its pricing capabilities and supports business growth.
