Here at SumUp, we're not just reshaping the way businesses handle transactions; we're revolutionizing the entire fintech landscape. SumUp is empowering small merchants in 36 countries to thrive in the digital age. Picture this: seamless payments at your fingertips, effortlessly bridging the gap between buyers and sellers. From bustling city streets to remote corners of the globe, our cutting-edge technology is democratizing commerce like never before.

  Exciting Opportunities:

Resilience: We are responsible for 90% of fees charged to SumUp merchants, so scalability and availability are major challenges.

Transparency: We handle fees charged to merchants, so it is always a sensitive topic when they think their fees are wrong. We aim to provide the answer to a single, but complex question: "How much did I pay for this transaction and why?".

Auditing: Fees are a very regulated part of our business. We have also to provide the means for regulators and auditors to investigate why a certain fee was applied or changed.

Automation: We provide a platform for fee change automation based on many variables, so we consume events from the whole company to determine the best fee structure for the merchant.

Expand Pricing Capabilities: Implement fee charging for all SumUp products, not just card reader transactions. This includes SumUp Bank, Card Not Present products, and Tap on Phone. Ensure the ability to apply different fees based on the specific SumUp product used.
