They build the pipelines for the other engineers as well as create warehouses at a large scale for data. Which takes a lot of time and helps analysts and scientists do their jobs.

Daily responsibilities Here is a general routine that might not be exactly followed by most of the data engineers. Firstly they start with maintenance work such as checking pipeline failures and looking into logs. All the found issues are fixed and it will take a lot of time.

Then they mainly focus on an ongoing project like creating a new pipeline. If the implementation plan is ready they have nothing else to wait for. Meanwhile, all the work there will be a continuous submission of duplicate or missing data complaints. These complaints take priorities mostly but sometimes the engineer keeps doing what he does.

It mainly includes programming languages and tools that were not part of the program you were enrolled in. It is also possible that those courses were not that important at that time and you don’t have a proper education.
