MetLife Japan Tech Stack

Japan's legacy life insurer modernizing core systems and security infrastructure

Insurance Chiyoda-ku, Tokyo 5,001–10,000 employees Public Company

MetLife Japan operates a large, compliance-heavy insurance business with 5,000–10,000 employees across Japan, running mission-critical systems on AS/400 and mainframe alongside cloud infrastructure (Azure, Azure Machine Learning). Current hiring (27 roles in 30 days) clusters heavily in engineering, finance, and security — reflecting active work on security infrastructure deployment, vendor strategy, and counterparty risk systems rather than consumer product innovation. The adopting stack (CyberArk, SailPoint) signals a shift toward identity and access management maturity, while pain-point data shows compliance, incident response, and capital optimization dominate near-term priorities.
