Banking Lisboa, Lisboa 10,001+ employees Founded 1876 Public Company

CGD is Portugal's leading banking group (10,000+ employees, founded 1876) with a 150-year history of domestic and Portuguese-language market presence. The tech stack reveals a transitional organization: Oracle and SQL Server anchor legacy banking systems, while simultaneous adoption of PostgreSQL, PyTorch, Hugging Face, and LangChain signals an active AI buildout. The current hiring focus on data, ops, and engineering roles—paired with active projects around RAG, LLM validation, and DORA implementation—indicates a push to modernize core banking infrastructure and risk controls, not peripheral innovation.
