The Role

Fidelity is seeking a Senior Fixed Income Quantitative Analyst to join its Quantitative Research and Investing division in Merrimack, NH. In this hands-on role you will lead the research, development, and implementation of quantitative risk and market models to support our Fixed Income investment processes. You will translate investment and risk-management needs into robust models and scalable analytics that help portfolio managers and traders understand exposures, evaluate portfolio construction choices, and assess new products and strategies. You will also contribute to our quantitative macro research effort: tactical asset allocation, alpha generation, translating macro fundamentals into market dynamics and quantitative signals for actionable, risk-adjusted investment strategies.

This is a rare opportunity to work with high caliber investment professionals in one of the premier fixed income investment management divisions in the world. As an ideal candidate, you will have demonstrated consistent success in your academic and work experience. You will have very strong analytical and communication skills and exhibit the highest level of personal and professional integrity. You’ll be able to think creatively, work independently, and make decisions quickly, often with limited information. Your ability to consistently develop, clearly articulate, and effectively communicate investment recommendations supported by a comprehensive and thoughtful research process is critical to success in investment management at Fidelity.

As an experienced individual contributor, you will own substantial risk model and macro research initiatives from inception and design through production implementation and ongoing monitoring. Success requires sound quantitative judgment, independent execution, and the ability to explain model assumptions, limitations, and portfolio implications to investment professionals and senior stakeholders. You will help set research priorities and technical standards, mentor other researchers, and partner closely with technology teams while maintaining the highest level of personal and professional integrity.

The Value You Deliver

•Help lead the development and enhancement of risk models for Fixed Income portfolios, including factor exposures, risk decomposition, and aggregation

•Develop scenario-analysis and stress-testing frameworks using both linear factor models and Monte Carlo simulations

•Establish model diagnostics, backtesting, documentation, and ongoing monitoring to assess model performance, data quality, and limitations

•Partner with investment and technology professionals to define requirements, prioritize enhancements, and deliver reliable production analytics embedded in investment workflows

•Communicate complex quantitative results, model assumptions, and actionable risk insights to portfolio managers, traders, and senior leaders

•Provide technical leadership, mentor researchers, and independently drive cross-functional model and platform initiatives from initial research through adoption

The Expertise and Skills You Bring

These attributes are indispensable:

•7 years of relevant experience in fixed income quantitative research or risk modeling, with demonstrated ownership of model development and implementation

•Strong communication and collaboration skills, with the ability to influence investment and technology stakeholders, mentor colleagues, and lead projects

•Deep quantitative modeling expertise, including statistical methods, factor risk models, scenario analysis, stress testing, and model evaluation

•Strong coding skills with experience delivering analytical libraries and production capabilities

These attributes are preferred:

•Advanced degree in a discipline of finance, science, engineering, or mathematics (PhD preferred)

•Experience building fixed income risk systems used for managing investments across a broad array of portfolio types and investment styles
