Senior Data Scientist (USA / Israel)

As a Senior Data Scientist, you will explore and analyze large volumes of data to gain insights and identify patterns relevant to your modeling objectives, including data cleaning, preprocessing, and transforming data into a suitable format for modeling. You will design and develop models using statistical and machine-learning techniques. This includes selecting appropriate algorithms, feature engineering, model training, and evaluation. You will be responsible for preparing the data required for modeling, including gathering and integrating data from various sources, ensuring data quality and consistency, and defining appropriate features and variables. You will assess the performance and accuracy of the models using appropriate evaluation metrics. You will fine-tune models to optimize their performance, improve accuracy, reduce bias or overfitting, and enhance the efficiency of the algorithms. The role requires experience in ad-tech, media/advertising platforms, demand-side platforms and supply-side platforms in digital advertising or retail-media networks.
