About the role

Role Overview:

As a Part‑Time Residential Mortgage Loan Underwriter Consultant at JazzX AI, you will leverage your deep expertise in underwriting to build AI-technology to support mortgage underwriting activities. You will work closely with engineering, and product teams to convert real-world underwriting decisions into robust AI logic.

Contract Duration: 6 months (potential to extend up to 12 months)

Key Responsibilities:

  • Underwriting & File Assessment
    • Underwrite a variety of residential mortgage loan files (purchase, rate‑term refinance, cash‑out refinance) per Fannie Mae DU and Freddie Mac LP guidelines.
    • Document underwriting rationale, risk profiles, and exception handling.
  • Process Mapping & Rule Development
    • Deconstruct end-to-end underwriting workflows—from borrower qualification and income/asset verification to AUS findings and final approval.
    • Identify critical decision points and edge cases crucial for AI modeling.
  • Model Validation & Feedback
    • Blind-test AI-generated underwriting recommendations against manual assessments.
    • Provide granular feedback to engineering teams to fine-tune decision rules and confidence thresholds.
  • Knowledge Transfer & Training
    • Create clear, actionable guides on complex topics, including compensating factors, manual AUS overrides, and GSE compliance.
    • Host virtual workshops or Q&A sessions to transfer domain knowledge to cross-functional teams.

Required Qualifications:

  • Experience: 4–10 years in residential mortgage underwriting at a senior or specialist level.
  • GSE Mastery: Deep, hands-on knowledge of Fannie Mae DU and/or Freddie Mac LP guidelines.
  • Analytical Acumen: Proven ability to assess borrower credit, income, assets, and collateral with accuracy and consistency.
  • Communication: Exceptional verbal and written skills to articulate underwriting logic and decision processes.
  • Consulting Approach: Comfortable in an iterative environment, providing structured feedback to product and engineering teams.

Preferred Qualifications:

  • Experience at large retail or independent mortgage lenders, such as Wells Fargo, Rocket Mortgage, or Chase.
  • Background in manual underwriting, AUS overrides, or secondary market delivery.
  • Familiarity with post-closing QC, servicing reviews, and secondary market delivery processes.
  • Prior involvement in technology or automation initiatives within mortgage operations.
