About SmartNews

News should be for everyone. But not when it’s buried under cat videos—or when your internet is spotty—or when it’s in a filter bubble. That’s why we created SmartNews.

Our mission is to discover and deliver quality stories to the world. To accomplish this:

We are a machine learning company. News should be impartial, trending and trustworthy. Our algorithms evaluate millions of articles, social signals and human interactions to deliver the top 0.01% of stories that matter most, right now.

We love content. News should be sustainable. We support quality journalism and respect publishers by sharing article traffic and revenue.

Please note that we will only consider you for one application at a time.

Position

About our Engineering Culture

Our global teams of engineers come from a variety of professional backgrounds, from large, well-established companies to small ventures. We believe that employees with diverse skill sets and life experience make for strong, cohesive teams.
