For you to consider before applying our job offer: In a small company organized the way we are, the traditional employer-employee relationship is replaced with a partnership. You cannot expect the same service, support, and infrastructure as you would in a large organization. Things you miss might need to be initiated and created by you. You are regarded as someone who is really important in terms of how our company is doing, not just as someone who comes in and does their job. You will have more responsibility for the whole picture, and you will also be able to have a greater impact than in a larger organization. You will feel a bit more insecure than you might in a larger organization. How the company is doing financially has a more direct correlation to your employment. The owners will work together with you, but they will not manage the company - you and your colleagues will. You will be required to contribute and take initiative. You will have to adapt to the fact that not everything will be in place, taken care of or running perfectly. To work in this way open and straightforward communication is essential. This is a strong part of our culture.
