Lead Quantitative Modeler

Job Description

As a valued colleague on our team, you will be responsible for leveraging expertise in economics, statistics (with a focus on time-series modeling), and advanced machine learning techniques (including reinforcement learning) to develop predictive models, optimize risk management strategies, and drive actionable insights. You will also act as team lead while conducting theoretical and empirical research with public and proprietary data in all areas of the mortgage finance business. This may include mortgage products and securities, borrower behavior, investment and hedging strategies, residential property valuation, macroeconomic models, including housing prices and interest rate, financial valuation of finance assets and derivatives, economic capital, and stress testing. Additionally, you will coach and mentor team members.
THE IMPACT YOU WILL MAKE
The Lead Quantitative Modeler role will offer you the flexibility to make each day your own, while working alongside people who care so that you can deliver on the following responsibilities:

• Lead the development and implementation of loan performance modeling frameworks, methodologies, and algorithms to predict borrower behavior, loan defaults, prepayments, and delinquencies.
• Conduct in-depth analysis of economic indicators, market trends, and macroeconomic factors to inform modeling assumptions, parameter estimates, and scenario analysis.
• Design and implement statistical models and time series forecasting techniques to analyze historical loan performance data, identify patterns, and forecast future trends.
• Apply advanced machine learning algorithms, including reinforcement learning techniques, to optimize risk management strategies, automate decision-making processes, and improve model performance.
• Collaborate closely with cross-functional teams, including data scientists, economists, risk managers, and business stakeholders, to gather requirements, define project scope, and drive model development efforts.
• Develop and maintain documentation, code repositories, and model validation reports in compliance with regulatory requirements and internal policies.
• Stay current with emerging trends, methodologies, and best practices in quantitative finance, econometrics, statistics, and machine learning, and apply them to enhance modeling capabilities and stay ahead of the curve.
