Swisscom operates as Switzerland's incumbent telco and IT services provider, serving both consumer and enterprise segments across telecom, cloud, and financial digitalization. The tech stack reveals a hybrid-cloud strategy (Azure + AWS + on-premise SAP), with PostgreSQL adoption and Oracle replacement signaling a shift toward open-source data infrastructure. Engineering-focused hiring (39 roles) alongside active migrations to AWS and core banking deployments suggest the company is executing large-scale platform modernization while managing legacy system complexity.
