Discover ING Hubs Romania

We started out in 2015 as ING’s software development hub – a distinct entity in relation to ING Bank Romania – then steadily expanded our range to include more services and competencies. Formerly known as ING Tech, as of 2022 we provide borderless services with bank-wide capabilities under the name of ING Hubs Romania and operate from two locations: Bucharest and Cluj.

PSS changes the organization towards a true Services-based organization and, to deliver on ambitious promises, we have organized ourselves into a strong strategic and commercially focused organization around our eight services, where our squads working on those products are enabled by clear prioritization, accountability, and capabilities.
