Meet Your Team: BI and Data Science

There’s no tech company out there without data. All of our products and their development are based on data, which is why the BI & Data Science team is at the heart of every company process – including product development and decision-making processes. As a part of the BI and Data Science team, you will be working closely with our WAVE product team. Did you know that in-app ads are sold in a real-time auction before they get rendered in thousands of mobile apps? It’s exactly for this that adjoe has built WAVE. Behind the scenes, we have an impressive prediction model working to figure out if an ad will lead to installing an app or not. The algorithm requires operating data from different data sources and performs calculations in real time. You’ll conduct research and investigations for the algorithm improvements and generate ideas for new features that could be included into the model. You will have access to state-of-the-art technology and work closely with the product and business teams to shape the future of adjoe’s core business and technologies.
