Santander Bank Polska operates as a universal retail and corporate bank serving Poland with 10,000+ employees across retail, SME, and enterprise segments. Since January 2026 under Erste Group ownership, the bank is pursuing aggressive digitalization—evidenced by active projects in GenAI architecture, credit process automation, and green finance—while hiring 309 roles in the last 30 days, weighted heavily toward sales (166) and finance (53). The tech stack bridges legacy banking infrastructure (Oracle, Java, Tomcat) with modern cloud-native tooling (Kubernetes, OpenShift, Python, PyTorch, TensorFlow, LangChain), and recent adoption of Python, VBA, Power BI, and Azure suggests a shift toward data-driven operations and cloud analytics.
