Senior Full-Stack Engineer

About Wunderkind:

Wunderkind ads are behaviorally triggered meaning that ads are served on a premium list of publishers only when a user is done consuming content. Our proprietary tag is integrated directly on the publisher page to track on-site user behavior - making net newad placements.Howwe serve the ad is why we are different from our competitors in-market.

Rather than placing an ad in front of someone while theyre actively trying to read content our technology patiently waits until a visitor has stopped reading before rendering our ad on the page. And that patience pays off -- it turns out that when an ad experience respects the users reason for visiting a page the user respects the ad experience in return. This unique brand safe approach to ad experience gives an advertisers message more attention and greater engagement.
