"In my experience, the difference between the two roles have varied depending on the organization. People in the two roles work closely together, but I believe have some general differences in their responsibilities. A Data Architect builds the data architecture for the organization's data systems and manages the servers. He/she maintains a holistic view of how the data moves into and throughout the organization. Data Engineers also may have a role in the building of the architecture, but in my experience his/her role is concentrated more on the testing and maintenance of it. In addition, the Data Engineer ensures high quality and reliable data is available to analysts in other parts of the organization."
