About this role

About the team

The Fixed Income Solutions (FIS) business at BlackRock sits within the Portfolio Management Group (PMG) and operates globally across London, New York, Atlanta, San Francisco, Gurgaon and Mumbai. FIS partners closely with clients to design, implement, and manage outcome-oriented investment solutions.

The Liability Driven Investment (LDI) business is a distinct part of FIS which leverages the breadth and depth of the entire platform when delivering investment solutions for our clients. BlackRock has been managing LDI mandates for over 20 years. We are passionate about designing and implementing fixed income solutions to help, primarily, pension fund clients to meet their long-term investment objectives. Our day to day activities range from monitoring the markets, modelling solutions and formulating the investment proposition, to trade construction, to designing the operational structure of the mandate and working with multiple BlackRock teams to implement it.

LDI Technology is a dedicated technology team embedded within the LDI business. The team's mandate is to materially improve LDI investment and client workflows by building high-quality, scalable, and well-governed technology solutions.
