About the job
Join SumUp, a leading innovator in payment solutions, empowering businesses to effortlessly accept payments, streamline order processing, sell online at lightning speed, and manage finances with greater efficiency. We develop essential tools that enhance both business operations and customer experiences.
Our payments processing platform, which encompasses several sub-platforms, has been the backbone of SumUp's global operations for over a decade. Developed in our vibrant Sofia office by the Payments Tribe—a dynamic group of cross-functional teams—each squad operates autonomously, focusing on their segment of the end-to-end platform.
As we expand and enhance our existing products while also creating new ones, this is an exciting opportunity for you to contribute. You will play a key role in refining and co-developing our microservices architecture, addressing scaling challenges and new development initiatives. Our primary focus areas include scalability and high availability.
