About the job

As a Data Scientist you will be responsible to assist our WAVE product team by gathering, interpreting and deriving smart conclusions based on data. You will have access to state of the art technology to implement new approaches on how to leverage our data assets with new ideas. adjoe is a leading mobile ad platform developing cutting-edge advertising and monetization solutions that take its app partners’ business to the next level. Part of the applike group ecosystem, adjoe is home to an advanced tech stack, powerful financial backing from Bertelsmann, and a highly motivated workforce to be reckoned with. 

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.

What You Will Do

    • You dive into state-of-the-art algorithms and deep learning models to create recommendation systems, predict user behavior, and/or optimise in-app retention.
    • You conduct research and hypothesis testing to come up with ideas that can improve our bidder algorithm.
    • You drill into data from various sources and write queries to generate insights.
    • You create, analyse and communicate reports and statistics to our business teams and partners.
    • You transform recurring analyses into KPIs and Dashboard Views we can easily monitor.
    • You act as an advocate for data-related topics in the company and become the go to person for stakeholders in your area of expertise.

Who you are

    • You have at least +4 years of professional experience in the Data Science field working in adtech, e-commerce, social media or a similar industry.
    • You have shown a great level of understanding of deep neural networks (libraries such as Tensorflow and PyTorch) and have experiences developing deep neural networks for recommendation systems.
    • Experiences in deep cross networks and multi-task deep learning is a plus.
    • You’re interested in big data and have outstanding experience in SQL.
