Senior Machine Learning Data Scientist

As a Machine Learning Data Scientist on Extend’s Risk & Fraud Machine Learning Team, you will develop and deploy cutting-edge machine learning models to detect and prevent fraud and abuse, enhance decision-making, and drive business value. You’ll work closely with product, engineering, and operations teams to build scalable, production-ready machine learning applications that support Extend’s post-purchase products, including product protection, shipping protection, and more. You will own the end-to-end ML lifecycle, including data preprocessing, feature engineering, model training, evaluation, validation, and deployment, and monitor and maintain models in production to ensure performance and reliability over time. The role also involves fostering a culture of learning, experimentation, and collaboration within and across partner teams.
