We\’re looking for a Treaty Actuary to support our Underwriting teams, providing expert actuarial insight across pricing, business planning, reserving and more. Your work will span both Property and Casualty business for Brit\’s London syndicates and our Bermudian entity, Brit Re.

As the go‐to person for underwriting, you\’ll dive into pricing models, develop and maintain them to align with underwriter priorities, and use your analytical skills to guide risk selection and improve portfolio performance.
