Job Description

How do you design and implement an API that communicates with thousands of cash registers in all stores of REWE, Penny and real,-? How do you automatically transfer money between different banks?

Software Engineer (f/m/*)

We operate Germany's largest independent payment infrastructure. Customers can use different services in several supermarkets to e.g. pay their invoices and deposit or withdraw cash from their private bank accounts using smartphone apps.

In the process of further developing our systems and implementing new projects, we are looking for software engineers that meet the following criteria:

• You love coding! Software development is not just a job for you. You code on private projects as well and you are interested in the industry’s latest developments. You are fluent in at least one programming language.
• In the future, you want to program in Ruby and Go! It would be awesome, if you have already worked with these two languages but in case you have not, that is also no big deal. In our experience, developers get productive in these languages very fast.
• You are interested in the big picture! You want to know and understand how everything is connected, starting with our public APIs, to our internal services and the PostgreSQL database. It is your goal to ensure an error free operation for all our production systems through a mixture of code reviews, unit + integration tests and monitoring.

We know you are in high demand. Here is why we are different and why you will love working for us:

• Our office is located in the middle of Berlin and is easily accessible using public transportation. 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 in 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" from the ground up and how to establish it in the market.
• After creating a solid base of operations in Germany over the last 8 years, we plan to realize several large projects in coming months, which build upon our existing payment infrastructure.

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

radio.net is an established startup with millions of users worldwide. For 10 years we have been the most successful radio app and website and now on the way to become the best podcast player. For this we need developers who want to find our product and our goals cool and want to move things in a great team.

You'll get a steep learning curve in our backend team with 4 senior developers. We work with agile methods and modern, automated release processes and a good work-life balance.

The day-to-day tasks mainly include designing new features, developing in Go, and integrating with our deployment pipeline with gilab and AWS CloudFormation. Your loyal fans are the front-end teams who are looking forward to any new or improved API endpoint.

We work according to the principle "you build it you run it". As we host on AWS, basically automating everything with CloudFormation and testing our releases very well, fortunately rarely gives a real problem and thus quiet nights.

You already have at least 2 years experience in software development with Java or Go and you are ready to develop yourself and your skills steadily. You've learned and sometimes used common best practices, design patterns and testing approaches.

Does that sound like a suitable challenge for you? Apply now via email to jobs@radio.net or directly via Stackoverflow and we will make a phone call in the next step.
