The primary responsibility of this role is to act as a lead contributor in the discovery and diagnostic of AI/ML model related risks including input data, assumption, conceptual soundness, methodology, outcomes analysis, benchmarking, monitoring and model implementation.

Specific Responsibilities

• Performs validation of Artificial Intelligence (AI), Machine Learning (ML) and Generative AI (GenAI) models
• Independently validate AI/ML and GenAI models across supervised, unsupervised, reinforcement learning and foundation model categories.
• Evaluate Gen AI model risk, including hallucination, prompt injection, data leakage, reproducibility, and alignment with Responsible AI principles.
• Assess model robustness, interpretability, fairness, and bias through quantitative and qualitative techniques.
• Has solid understanding of risks that are posed by AI/ML models (Fairness, Privacy, Transparency and Explainability, etc.)
• Has familiarity in financial models used in portfolio analysis, asset management, Value at Risk, Monte Carlo, CAPM, Factors.
• Has fair understanding of stress testing, CCAR, CECL, etc.
• Solves complex quantitative problems and takes a new perspective on existing solutions.
• Acts independently and analyzes possible solutions using technical experience and judgment and precedents.
• Develops and maintains an understanding of many algorithms across supervised learning, unsupervised learning and time series analysis.
• Utilizes expertise in machine learning algorithms and statistics to challenge how algorithms are selected, trained and tested.
• Also performs reviews of bank-wide quantitative models including models used for CECL and CCAR/DFAST stress testing, credit risk loss projections (PD, LGD, EAD), operational risk, interest rate risk models, AML (Anti-Money Laundering and Fraud Detection), and various machine learning models.
• Ensure model development, monitoring, and validation approaches meet regulatory expectations such as SR 11-7 and internal risk management needs.
• Evaluate conceptual soundness of model specifications; reasonableness of assumptions and reliability of inputs; completeness of testing performed to support the correctness of the implementation; robustness of numerical aspects; suitability and comprehensiveness of performance metrics and risk measures associated with model use.

• A College or University degree in STEM field, mathematics, actuarial science, engineering or statistics or related discipline (Advanced degree preferred).
• Strong knowledge of AI/ML techniques including classification and clustering, gradient boosting, neural networks, NLP models, and foundational models like GPT, BERT, etc.
• Experience in validating machine learning models for performance, fairness, explainability, and compliance; Familiarity with GenAI risks and controls: hallucination detection, retrieval-augments-generation (RAG), prompt engineering, etc.
• Good interpersonal, verbal, and written communication skills.
• Programming experience in Python required, experience in SAS and R desired.
• Mastery of analytical tools, such as, Excel as well as Word and PowerPoint is required.
• Deep understanding of linear regression and logistic regression.
• Familiarity with cloud data technologies is desired.
