Who is Azure Data Engineer?

Azure Data Engineers are responsible for clearly separating and differentiating raw data into structured data. They integrate, transform and consolidate data from unstructured data into structured data. And this structured data is used for building analytics solutions.

Moreover, they help the stakeholders to clearly understand the information through exploration. They construct efficiently and design particular instructions for processing pipelines with the help of specific tools and strategies. To produce better data for evaluation, they use Azure data offerings and languages.

Following are the responsibilities of an Azure Data Engineer:

  • Developing and designing data processing and storage solutions for enterprises.
  • Install, configure, and manage cloud-based data services, such as databases, blob services, and analytics.
  • Securing the stored data and the platform, so that only necessary users have the access to the data.
  • Monitoring the systems to make sure it is running properly and are cost-effective.

Data engineers are the people who understand and connect the raw data into structured data within a company. They accomplish this by doing,

  • Accessing, collecting, auditing, and cleaning data from systems and converting it into useable data for enterprises.
  • Maintaining the database
  • Building pipelines
  • Monitor and manage data systems
  • Creating data scientists’ output in a scalable manner.

So, they are the front lines of data strategy, the first people to tackle the unstructured data and convert it into structured one. They are people on whose shoulders data analysts and data scientists stand.

For this reason, there is a huge demand for Data engineers in the IT sector, as they daily produce raw data.

As for some resources, the average salary for a Data Engineer is $116,591. It is also known that they make 261% more than the national average salary.
