This is because configuration work can largely be done remotely, though Portuguese banks under the Banco de Portugal's oversight generally keep core-system specialists on a hybrid schedule. Where in-office attendance is required, it is typically driven by go-live cutover windows and integration testing require on-site coordination with core teams, and Banco de Portugal compliance sign-off pushes most Portuguese banks toward a fixed office presence during migrations.
