THE POSITION 
Wellington is seeking a quantitative risk-neutral valuation specialist in fixed income, MBS, and structured products modeling to join the Risk and Analytics Research team within Wellington Investment Risk. The team is responsible for investment analytics and risk modeling, partnering closely with investors and risk professionals to embed analytics and models into investment decision workflows, and working with technology teams to deliver scalable, enterprise-level solutions.

The Quantitative Strategist will develop models for fixed income, agency MBS, and structured product instruments; conduct empirical research on security valuation and risk premia; and serve as a subject matter expert on risk-neutral valuation for investors, product management, and the Investment Risk team.
