Senior .NET Developer

Dept, Rotterdam

The heart and mind of your digital business.

For our Rotterdam and Amsterdam offices, we are looking for a Senior .NET developer who knows that there is rarely one solution to a specific problem.

As a Senior .NET developer you will use your knowledge to find that one best solution for our customers, which you are able to explain in an understandable language.

Moreover, you'll act as a mentor for others. We don't have a lot of office doors, but yours is always open for our juniors and mediors seeking advice, development or anything else in order to grow. This way, you'll get the most out of your client while taking your colleagues to the next level.

You will work in a vibrant environment with clever minds that work for a variety of large global clients. Yes, we are eager to hire the most talented experts in the game but we are also looking for a perfect Dept-fit. Someone who is eager to learn, inspires, strives towards a better world, takes the stage, a futurist at heart, and someone who will toast to a successful week with us.
