Irreplaceable: you

Bugs are like predators in the dark: feared by all, visible to only a few. Which makes testers like modern-day knights. Their mission: to seek, to discover, to report… and to be rewarded with money and glory.

Each individual tester helps make software better and more secure, and forms a part of a worldwide community: the crowd. The light in the darkness, the crème de la testing crème.


Work where you want, when you want—to some extent even how you want. Testers select their jobs from a list of options that fit their capabilities. Each tester is his or her own boss.


Keep your finger on the pulse of the development world, and learn something new every day. As a tester, you’ll be one of the first people to try the very latest apps, and the experience you gain in the tester academy will increase your qualification level more and more.


Earn up to €50 for each bug you find, depending on specifications and relevance. Different scenarios use different compensation models, including fixed payment amounts for defined test cases.
