Developer C#


Long story short 

At Brand New Day we tend to do things differently. We’re definitely not boring or bureaucratic like any other bank or insurer. We don’t belong to one neither. We aren’t traditional bankers, but entrepreneurs. We just want to build the best bank for long term consumers savings and investment. In order to do that, we need the best development teams. We know this sounds like a marketing story. It isn’t. We honestly believe in doing things our own way and challenging the status quo. Still not convinced? Come in for a coffee with our lead developer or IT director. Or speak to the teams and see for yourself. 

What you will be doing  

We promise top-quality service to each and every one of our customers. That means almost 300,000 people have exceptionally high expectations of Brand New Day. We try to fulfil those expectations by creating our own systems. Next to working on clients or business needs, you spend 25% of your time working on technical projects, like Brand New Day development working towards CI/CD, central logging and monitoring based on Elastic and experimenting with and implementing the newest techniques. Just as important, however, is that you enjoy working together closely with a bunch of other talented developers and testers in an international setting.
