As a Senior Mobile Engineer (iOS) in Global Bank you will be part of one of our small highly skilled cross-functional teams and work together with Product Managers, other Mobile Engineers, Product Designers and more. You will also be part of and collaborate on a global level with the broader Mobile chapter. 

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. You are someone who puts user needs in the center of the product you are building. 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.

The role is based on-site in our office in Berlin/Sofia/Vilnius/London. We believe in the power of face-to-face conversations that happen organically when working next to one another.
