The role offers an opportunity to move from fundamental asset auditing into capital-markets pricing, structural modeling, and asset-backed transaction execution.

The position involves analyzing loan data and collateral quality, supporting cash flow modeling for Prime, Non-QM, and CRT securitization shelves, preparing portfolio reporting, and coordinating file validation with external diligence houses, rating agencies, audit teams, credit managers, custodians, and originators. The role is performed in a professional office environment. Applicants must be legally authorized to work in the United States; visa sponsorship is not available.

Requirements

• Bachelor’s degree required, preferably in Finance, Quantitative Economics, Mathematics, Engineering, or another heavily analytical field.
• 1 to 3 years of experience in residential mortgage banking, capital markets, warehouse lending, or structured finance analytics.
• Advanced Microsoft Excel capabilities.
• Basic conceptual understanding of residential mortgage metrics, including prepayment and default curves, amortization schedules, and fundamental credit concepts.
• High intellectual curiosity, strong attention to detail, and strong self-organization.
• Ability to communicate technical findings to a broad range of team members.
• Must be legally authorized to work in the United States; the position is not eligible for visa sponsorship.

Responsibilities

• Perform technical due diligence on residential whole-loan data files, validating structural features and credit attributes such as FICO, DTI, and LTV, and checking compliance with underwriting or programmatic guidelines.
• Identify collateral data gaps, loan-tape discrepancies, and document exceptions; coordinate with credit managers, custodians, and originators to resolve exceptions ahead of settlement or securitization deadlines.
• Monitor collateral-quality metrics, including DSCR, loan-to-value fluctuations, and geographic concentration.
• Support senior analysts in building, updating, and stress-testing cash flow models for non-agency securitization structures, including Prime, Non-QM, and CRT shelves.
• Analyze securitization cash flow waterfalls and assess how prepayment speeds (CPR), default rates (CDR), and loss severities affect senior and junior tranches and bond yields.
• Use Microsoft Excel and specialized industry software to map loan-tape data into securitization models.
• Ingest and normalize raw loan tapes from originators or sellers for structured analysis.
