PayPal is seeking to independently validate and provide oversight of high-impact statistical, machine learning, and AI models across key business areas such as credit, fraud, marketing, and collections. The goal is to assess model soundness, data quality, and performance to identify and mitigate model risk, while supporting AI and model risk governance to ensure compliance with PayPal’s enterprise risk framework and evolving regulatory standards.
Requirements
- Experience with ML frameworks like TensorFlow, PyTorch, or scikit-learn.
- Familiarity with cloud platforms (AWS, Azure, GCP) and tools for data processing and model deployment.
- Several years of experience in designing, implementing, and deploying machine learning models.
- Proficiency in programming and big-data technologies, with hands-on experience in tools such as Python (Scikit-learn, TensorFlow), SQL, Hadoop, and Spark.
- Strong knowledge of statistical and machine learning techniques, including but not limited to logistic regression, time-series modeling, random forests, support vector machines, gradient boosting (e.g., XGBoost), and deep learning architectures (e.g., CNNs, RNNs).
- Relevant modeling experience in one or more of the following domains: credit risk scoring, fraud detection, financial forecasting, or marketing analytics - gained through industry or academic research.
Responsibilities
- Develop and optimize machine learning models for various applications.
- Preprocess and analyze large datasets to extract meaningful insights.
- Deploy ML solutions into production environments using appropriate tools and frameworks.
- Collaborate with cross-functional teams to integrate ML models into products and services.
- Monitor and evaluate the performance of deployed models.
Other
- 3+ years relevant experience and a Bachelor’s degree OR Any equivalent combination of education and experience.
- Advanced degree (Master's or Ph.D.) in a quantitative discipline such as Statistics, Mathematics, Computer Science, Engineering, or a related field.
- Strong collaboration and communication skills, with the ability to work effectively both independently and as part of a cross-functional team.
- Ability to articulate complex technical concepts clearly to non-technical stakeholders and build constructive working relationships across functions.
- Experience with Large Language Models (LLMs), Agentic AI, or related generative AI applications.
