What can you expect from us?


It's about what you deliver. How, when and where? That's up to you. From our inspiring office or from your well-facilitated home office. First take the children to school in the morning or do some sports in the afternoon and then get back to work full of energy. Do what works best for you.

Of course you have a very nice job at VIKTOR ;). But other things are important too, such as family, friends and hobbies. Working overtime is avoided as much as possible.

Awesome team

Be part of an enthusiastic and driven team. We have a lot of fun and there is a plenty of room for ideas and initiatives. The most brilliant ideas often arise during a team outing, drinks or team building day. The weekly demos give you a good idea of what other colleagues are working on and how the platform is evolving.
