• Review implementation of models and algorithms focusing on requirement verification, coding, and testing quality
• Conduct comprehensive quality assurance testing on model library including construction of test cases, automation of model unit testing and creation of reference models if needed
• Participate in model code reviews, model release testing (including margin impact analysis and baseline support and troubleshooting during model library integration with production applications) and production support
• Provide production support, participate in troubleshooting and analysis of model, system and data issues
• Support the launch of new products
• Provide quantitative analysis and support to risk managers on pricing, margin, and risk calculations
