DoubleVerify

DoubleVerify improves the impression quality and audience impact of digital advertising. We ensure ad viewability, brand safety, and fraud protection for hundreds of Fortune 500 companies. Our team in Belgium optimizes hundreds of millions of video ads per day. We also do a fair amount of data science. We're a full-stack JavaScript team, but we focus on computer science fundamentals rather than specific tech. In fact, many of our top engineers started out without any JavaScript experience! If Belgium's not your thing, we're also hiring talented engineers at our offices in New York and Tel Aviv.
