About the Role

At LM Re, our pricing transformation is a live, multi‑year initiative to migrate the majority of LM Re pricing models onto the hx platform, using a modular, reusable architecture across classes of business rather than traditional line‑of‑business models. This project is one of several high‑profile investments aimed at transforming the LM Re business capabilities through people, process, data & technology change.

Reporting to the Head of LMRe Portfolio, Pricing & Analytics, this role supports the delivery of a high‑profile Global Reinsurance Pricing Platform built on hx Renew. The cloud‑based, fully integrated solution enables Underwriters and Actuaries to move away from team‑specific pricing tools and supports enhanced risk decision‑making through improved data aggregation, global pricing consistency, and increased efficiency.

As part of an Agile delivery team, the role works closely with Actuarial, Underwriting, Business Agility, Technology, Operations to support the implementation of a best‑in‑class pricing platform. The role strengthens pricing model foundations, embeds best practice, and helps build durable platform capabilities that minimise rework, technical debt, and integration risk as the platform evolves.
