Dragonbox, a Kahoot! Company, is in an exciting moment as we expand the reach of our innovative learning software. We're looking for someone with a broad range of practical experience to work across teams and take ownership for the operational and analytic capabilities of our commercial groups (i.e. Sales, Marketing, etc.). You should be comfortable working in a collaborative environment, able to follow common architectural patterns as you design and implement data services and pipelines, willing to learn how to customize and configure 3rd party systems, and motivated by our mission to deliver the best learning experiences to children.

Does this sound like you? We'd like to hear from you. Concerned that your CV doesn't contain the right tech buzzwords? We'd still like to hear from you! We're not obsessed with the specific web technologies you've worked with considering the programming world is in perpetual revolution. Learning is at the core of our company philosophy and it's important that our hiring process reflects this.

Note: At the moment, we’re only accepting candidates physically located in a country in which Kahoot! maintains an office (Norway, Poland, Spain, Denmark, France, Finland). Within one of these countries, remote work is fine although there may occasionally be a need to come to the office.
