Who are they looking for? This is a rare role and they know it. They’re looking for someone who brings genuine breadth across underwriting analytics, pricing, and data science, someone who understands how insurance portfolios actually behave and can work credibly with underwriters, not just alongside them. Your background might span underwriting analytics, actuarial work, pricing, or a mix of all three. What matters is that you think rigorously about risk, can build and deploy models that shape real decisions, and can explain complex findings clearly to senior stakeholders. On the technical side, Python or R, SQL, and experience with modelling techniques like GBMs are important. Fraud analytics experience is a plus, as is data enrichment, though fresh thinking on both counts matters just as much as direct experience. Cloud data warehouse experience such as BigQuery or Azure is useful but not essential.
