Portfolio Steering & CAT Risk Analyst, Marine

We are looking for a Portfolio Steering and Cat Risk Analyst for our Marine team based in the London or New York City office.

The specific nature of Marine risks, including static and non-static exposures, requires management within a consistent global framework.

Detailed business monitoring and portfolio steering activities require sustained involvement and analytical focus. This role is vital to understanding exposure hotspots, market changes that affect a portfolio, and related trends/changes within the competitor landscape.

Our team combines portfolio steering expertise with advanced catastrophe risk analytics to drive informed decision-making across our Marine line of business.

Partnering with CAT Management and CFO Risk Management, you will ensure consistency with our overall accumulation strategy, accurate reporting of Marine values, and the appropriate reflection of risks in pricing and model development.
