You will work representative borrower scenarios end-to-end, document how loan officers qualify, structure, and price loans, map the lead-to-lock-to-submission journey, and sit with product managers and engineers daily to translate that knowledge into detailed product requirements, decision logic, and acceptance criteria. This role exists to close that gap: you will embed with the product team as a hands-on domain expert, bringing real operational mortgage experience into product design and product build at a very detailed level — from workflow maps and edge cases down to field-level definitions, decision rules, and acceptance criteria.
