• Generate automated reports, summaries, and data analyses.
• Translate existing underwriting and pricing rules into repeatable automated workflows.
• Apply standardized rubrics to evaluate properties, borrowers, and loan scenarios.
• Identify errors, missing information, inconsistencies, and potential non-compliance within processing requests.
• Develop an automated final loan-file review process that validates 20+ required data points before funding.
• Implement controls to verify both the completeness and accuracy of critical loan information.
• Design appropriate validation, auditability, and human-review mechanisms for AI-generated results.
• Work with business stakeholders to understand lending workflows and convert them into technical requirements and automated solutions.

Loan Pricing Automation

A major initiative for this role will be designing and implementing an intelligent loan pricing solution capable of:

• Collecting the required loan scenario information from borrowers.
• Validating borrower-submitted information before pricing.
• Processing borrower and property characteristics against lending criteria.

• Extracting pricing information from PDF and Excel lender rate/pricing sheets.
• Accessing available online lender pricing tools and websites, including authenticated sources where technically and contractually permitted.
• Normalizing information received from different lenders and formats.
• Applying lender-specific rules and pricing logic.
• Generating multiple relevant loan options based on the borrower’s scenario.
• Presenting loan options in a structured and understandable format.
• Maintaining traceability between source information, pricing logic, and generated results.
• Supporting updates as lender criteria, pricing sheets, and underwriting requirements change.
