They run two complementary GenAI platforms: a broadly deployed AI assistant used across the business for summarisation, Q&A and decision support, and a set of advanced, use-case-specific GenAI tools embedded directly into core underwriting and claims workflows. They're building this out as a long-term, unified platform strategy rather than a series of one-off pilots. The Role You'll join a full-stack engineering team building, maintaining and scaling this GenAI platform, working across front-end and back-end delivery as well as the cloud and integration work needed to bring GenAI capabilities into high-value business workflows. You'll collaborate closely with platform, data and product teams, contribute to integration between the two GenAI platforms, and help embed responsible AI and operational resilience practices into everything shipped. It's a strong fit for someone who enjoys full-stack ownership and wants exposure to genuine production GenAI work rather than proof-of-concept builds.
