Data Cleaning and transformation are the most important reasons why Data Engineers are in demand.
The data a company gets is unlabelled with lots of missing information. The responsibility of a Data Engineer is to clean, transform and label such data before taking it into action.

As a Data Engineer, you should know how to store and manage a company’s data from multiple sources in the cloud. It is one of the responsibilities of an experienced Data Engineer.
Design and Develop Data Pipelines
Data Pipeline is a step-by-step process of data processing elements connected in a series. A data pipeline is designed in a way that the output of one step is the input of the next step.
As a Data Engineer, it is your responsibility to design and develop data pipelines that take raw data as input and prepares it step by step for analytical, modelling, storage, and other data science purposes.
So the day to day role and responsibilities of a Data Engineer are:
- data collection according to business needs
- data cleaning and transformation
- data warehousing on cloud platforms
- design and develop data pipelines
