About the role

As an iOS Engineer, you will be part of one of our small and highly skilled cross-functional teams and work together with Product Managers, Backend Engineers, Android Engineers, Product Designers, and more. You will also be part of and collaborate on a global level with the broader Mobile chapter.

You will deal with a variety of topics ranging from improving reliability of Bluetooth implementation within the iOS SumUp app and the SumUp SDK, to implementing user-facing features such as screens to interact with card readers, to collaborating on developing technical roadmaps.

You should be a mobile engineer with a product mindset who can fully own the features you are working on and remain flexible with changing priorities.
