• You are interested in the big picture! You want to know and understand how everything is connected, starting with our public APIs, over to our internal services and the PostgreSQL database. It’s your aspiration to ensure an error free operation of all our production systems through a mixture of code reviews, unit + integration tests and monitoring.

High requirements merit appropriate compensation. We are competing with other companies for your time and knowledge. So why should you decide to join us? Naturally this is quite hard to answer and depends on a lot of factors. Therefore we would be happy to answer all your questions regarding Barzahlen in a personal chat.

You can expect the following working for us:

• Our office is located in the middle of Berlin and easily accessible using public transport. We will procure your preferred technical devices, so that you can code as productively as possible. We also offer flexible working hours and the possibility to develop yourself further not just in your work related area of expertise but other areas as well.
• We have experts in the IT as well as in all other departments with excellent connections to other companies throughout Berlin and Germany. You can learn a lot of new things and experience how to build a "FinTech-Startup" from the ground up and to establish it in the market.
• After creating a solid base of operations in Germany over the last 4 years we plan to realize several large projects in the coming months which build upon our existing payment infrastructure.

We will be happy to tell you more about this in a personal chat :)
