Teams own what they design and run, end to end, on platforms that serve the group’s markets and brands across Europe. The Cluj engineering hub is part of a wider international ecosystem. The culture actively encourages experimentation and new ideas, and the local capability continues to grow. About the role As a Data Quality Engineer, you make sure the data flowing through the enterprise data platform can be trusted.
