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.
To be successful in this role you should be able to follow good software engineering principles, write clean code and tests, and be open to constantly learning and improving your craft. It will be expected from you to not only ship features, but also to contribute to the decision making process.
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.
