For this position we're looking for someone that meets our definition of senior: the ability to design, deliver and maintain code, without daily instructions. However, we greatly value continuous communication of any ideas, decisions and problems.
Ideally, you are comfortable with some of the following:
Let's be honest: employees choose companies as much as the other way around. We want to work with people that feel welcome here and whose company we enjoy, in Slack or in real life. You will work with a small team of highly skilled and motivated people. We have long running and one-off projects, but usually don't have anyone working on more than one project at a time.
We'd love a GitHub profile as part of your application, but we're also aware that some people do their best work in private repositories. So we ask you to choose anything (App Store link, GitHub, open source project, conference talk, etc.) to share with us that demonstrates your coding style. You also should be based in central Europe and be fluent in English as well as German.
