SeniorDataScientist

## Description We are looking for a Senior highly technical Data Scientist to join our established Analytics department. This is a modeling-heavy role focused on building high-performance, reproducible machine learning systems that drive core business decisions. You will join the newly formed AI Lab which is entrusted with growing our AI/ML capabilities at IDT. We are looking for a veteran modeling expert who thrives on building novel ML architectures from the ground up for business functions like fraud detection, customer engagement, process performance and finance. ## Responsibilities Advanced ML R&D: Design, develop, and maintain cutting-edge, custom machine learning models for production environments.Behavioral Forecasting: Build advanced models to predict bad actors in our transaction flow.End-to-End Modeling: Develop and implement both supervised and unsupervised models from scratch to find anomalies and next likely outcome.Content Generation: Design generative models based on profile and transaction data.Production Deployment: Deploy models into product in a real-time environment.Interact with MLOps functions to maintain models and increase accuracy, recall and precision.Experimental Design: Lead the statistical design and analysis of A/B testing to validate model performance and business hypotheses. ## Requirements Experience: 5+ years of professional experience in Data Science, with a strong portfolio of building and shipping original ML models. Deep theoretical and practical understanding of supervised/unsupervised learning, including Boosting, NN, Bayesian, Clustering, and related frameworks.Core Stack:Python: Advanced use of Pandas, Numpy, PyTorch/TensorFlow, and Scikit-learn for complex feature engineering, custom model design, and pipeline optimization.SQL: Proficiency in querying and structuring data from large-scale databases.MLOps: Experience using MLOps tools like MLflow or ClearML in model development and inference.Education: Bachelor’s degree in
