MassMutual operates a large financial-services organization built on decades of legacy infrastructure (COBOL, mainframe, DB2) while actively migrating to SAP S/4HANA, cloud platforms (AWS, Azure), and emerging AI tools (RAG, GitHub Copilot). The hiring mix—finance-heavy with 57 roles, balanced by 25 engineering and 15 data positions—reflects a company mid-transition: modernizing core ledger and policy-accounting systems while automating quant research, investment operations, and financial forecasting.
