I'm doing Data-oriented JS development in the Insights team, which is in charge of audience research and knowledge of readers' uses. My role is to measure, collect and exploit the data. I have to communicate with different teams such as the web, data or marketing team depending on the nature of my work. Technically, I "tag" elements of the DOM to bring back data within different measurement platforms with a particular focus on the performance of the product code. I then participate in the analysis of the data which can have different goals such as providing a better user experience or affirming a trend.
