Hannover Re is a major reinsurer transitioning its legacy SAP environment to SAP S/4HANA while adopting modern development tooling (GitHub Copilot, Groovy, Kafka, Kubernetes). The hiring mix skews heavily toward finance (51 roles) and engineering (19), with active projects centered on underwriting automation and process digitalization—signaling a shift from manual risk assessment toward data-driven, automated decision-making. Leadership gaps in underwriting efficiency and cloud spend optimization point to execution friction during this modernization cycle.
