What we offer

Career development

We want the company to evolve – and we want everyone to flourish with it. Our career development options include full time employment, competitive salaries and extra bonuses.

Global reach

Our work, team, partners and mindset are international. We take great pride in our global outlook and continuously learn from it.

Work environment

We strive to offer superb working conditions and wellbeing at our company: from lovely office environment, necessary tools and equipment, to fully stocked kitchen and bookshelves. And we don’t mind a furry assistant either (yes, we’re talking about dogs).

Work ethics

It’s important that work gets done – but it’s even more significant how it gets done. We stick to a limited hour work week, encourage remote work, and put family first.


We don’t take shortcuts. We offer medical insurance as a part of the Slovenian national healthcare system, actively take health precautions, and support and organize sport activities.


Social bonds are an important part of team and work dynamics, but are also a bedrock for the community around it. We strengthen these bonds at informal events and of course, around food.

Social awareness

Everyone decides for themselves how to contribute to a better society. As a company, we support and contribute to various causes with sponsorships, donations, volunteer work and mindfulness.
