What would be your role?

Here at Casumo, we have our lovingly crafted desktop app, our award-winning mobile app, and a suite of bespoke tools to support us in being the best we can be. But now it is time for a new challenge. As part of the team, you will help guide this new idea in collaboration with a full stack team of developers and designers, while working closely with our content producers, marketing gurus, player ambassadors, and anyone else who wants to get involved.

Collaboration works best with excellent communication so you will need to share what you are up to with the team, and reach out for help when you need it. We all share the responsibility for improving our products, our code and our teamwork so you’ll need to get involved, and above all be the change you want to see.

Who are you?

You are a javascript developer who has worked on a number of interesting and successful React/React Native projects, where you have needed to collaborate but also driven the project forward yourself. You are an open minded, honest and a driven problem solver who is, not only hungry for more learnings but also able to spread knowledge to others around you.

Casumo is a recognized and award-winning online casino formed in 2012. We’re a bunch of nerdy game enthusiasts who believe that the right people, tools and technology drive innovation and have the potential to disrupt entire industries.

As the gaming world zigs, Casumo zag. We will not only challenge the other gaming companies in the industry—we will challenge all their conventions about how to be a gaming company. We don’t believe that casinos always will look the way they do today, and we want to be the thought leader driving that change. It’s a long process but it all revolves around one question: how will chance based gaming about money work in the future?

We’re a flat organization which means we stay away from unnecessary titles and corporate gibberish. Our work style is characterized by transparency, humbleness and speed, with autonomous, cross-functional and highly-skilled teams working closely together towards a clear vision. The possibility to create something new and to make a real difference is what really drives us. Together, we’re writing the future of gaming.
