Senior Data Scientist

The Job:

The internet is a vast ocean with millions of options, and it is growing by the minute. Brands today try to help us make sense of this madness with personalized recommendations based on our behaviours and purchase histories. But human beings are more than just that. Our personalities, motivations, and desires play a vital role in almost every decision we make every day. How much time can I invest? Can I afford it? How will it make me feel? These are but a few of the many questions that run through our minds before, during, and after a purchase.

To create the truly personalized experiences of the future, it is essential to understand the person behind the purchase. By combining your expertise in machine learning, our knowledge of games and a profound understanding of the human mind, we are going to build a video game recommendation engine that will allow us to make recommendations that align with people's fundamental motivations every single time.

We are a global team of 170+ tech junkies who manage one of the world's largest living libraries of video game metadata. Through partnerships with some of the world's biggest technology companies, our data receives billions of impressions every month and now we want you to help take us to the next level.

Key Responsibilities:

• Selecting features and building recommendation engines using machine learning techniques.
• Data pre-processing using state-of-the-art methods.
• Enriching the company's data from third-party sources when required.
• Enhancing data collection procedures to include information that is relevant for building analytical systems.
• Creating automated anomaly detection systems and constant tracking of the performance of the Recommendation Engine.
• Develop custom data models and algorithms to apply to data sets.
• Assess the effectiveness and accuracy of new data sources and data gathering techniques.
• Coordinate with various devs and businesses to implement models and monitor outcomes.
• Develop processes and tools to monitor and analyze model performance and data accuracy.
