The Artificial Intelligence Model Development Center of Excellence (AI MD CoE) is a data science team, responsible for developing and deploying machine learning, NLP, and AI solutions for a number of domain areas such as fraud prevention, credit risk, experience personalization, customer listening, risk and compliance, anomaly detection and operational improvement. The CoE partners closely with the AI Enterprise Solutions and the AI Technology teams at the bank, and brings a cross-functional approach to identifying, developing and deploying AI solutions. The CoE requires high-skill/ high-motivation individuals who enjoy working collaboratively in a team setting, used to taking decisions autonomously and comfortable with a dynamic work environment.

The NLP Data Science team in the AI MD CoE is responsible for developing and deploying NLP, machine learning, and AI solutions for key strategic Enterprise initiatives such as customer experience improvement, risk management and compliance, business operational excellence, and team member experience that leverage unstructured data. The team is looking for an experienced AI model professional to add to its NLP model development team.

You will be responsible for designing, developing, and implementing AI/ML models to support various initiatives across the enterprise. You will leverage unstructured data such as emails, text messages, notes, voice data, and semi-structured data in combination of structured data to build NLP Machine Learning/Deep Learning models using open stack languages (mainly Python/PySpark/PyTorch). You will collaborate with LOB organizations to frame the problem, explore various modeling methodologies and tools to deliver business solutions according to timelines. Collaborating with WF AI Tech, AI business, and LOB leads, you will develop, deliver, and deploy AI/ML models on the Wells Fargo AI open source platform, scale them up, and operationalize them for business use. You expect to follow and contribute to the Model Development Life Cycle that focuses on generating standardized processes, repeatable modules, and required artifacts to scale up model development, model review, and validation. You will ensure the modeling processes and procedures meet corporate model risk policy and requirements. You will also be working with AI vendors to ensure vendor AI models pass Wells Fargo model risk policies and requirements including model development documents and reviews.

KEY RESPONSIBILITIES INCLUDE:

As part of the NLP data science team, you will work within the team to follow and develop AI solutions according to the MDLC process:

• Design, develop, and deploy AI/ML models using state of the art techniques available in the open stack (Python/PySpark/PyTorch) and/or vendor solutions
• Partner with LOB leads to frame the problem, explore various ML/DL model architectures and methodologies, generate required artifacts related to model development life cycle (MDLC), author the model development document, and deliver AI models that meet business needs
• Adhere to corporate model risk policy and ensure compliance with model risk management
• Working with other data science teams to identify, gather, retain, and publicize modeling artifacts required for approved and repeatable processes
• Work with AI technology and production teams to operationalize models
