Your impact at SumUp

You’ll shape the core experience of merchants who are using the Android App on a daily basis.

In the first few weeks, you'll dive into the code and learn how to create clean, composable components in our codebase. You'll use this knowledge to start developing and refining features. You'll learn how we write tests and how we keep performance tip-top.

In the first three months, you'll develop major features that impact our merchant base. You'll work closely with product and design departments to build features that are maintainable, usable and beautiful. You'll help us re-think problems we've solved before in a different way as needs evolve.

By the end of your first year, you'll have a wealth of knowledge about our complex problem domain, as well as its implications in the interface and in the backend – and how to manage it in a clean way. You'll have launched numerous features in the Android App as well as in the Android SDK.
