We are looking for strong candidates that have an interest in helping us get there and building great products along the way. If you feel like one of these people, our office in Cologne is hiring for the position of Senior iOS Engineer
What you’ll do
You’ll shape the core experience of merchants who are using the iOS App on a daily basis.
In your 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, how we manage bluetooth communication, 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 rethink problems we've solved before in a different way as requirements 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 iOS app as well as in the iOS SDK.
You’ll be great for this role if:
You’re comfortable with Objective-C and the iOS system frameworks.
You have an in-depth knowledge of Swift.
You know what to test, why to test it, and how to write flexible tests that won't break.
You care about user interaction, usability and of course, making the interface beautiful.
You strive for clean code, but also know how to make your "shortcuts" easy to delete in a crunch.
You love coding and take the time to reflect on all aspects of your implementation, be it the frameworks, languages or processes.
You also know how to get things done on the command line.
You aren’t afraid to ask for help or to use Google when something is beyond your grasp.
Your precise communication skills make working in a distributed team effective and efficient.
Technology excites you and you strive to learn something new on a daily basis!
The Mobile Team: You'll be with people who care about mutual learning, keeping our technical knowledge up-to-date, and discussing ideas that contribute to not only the company's success but keeping everyone well-rounded and hands-on.
