If you do not know much about the analytics industry, you may be under the impression that a data scientist and a data engineer do the same thing-they analyze data and deduce insights from them to come up with business solutions. Though they both work with data, a data engineer and a data scientist have a different set of responsibilities. 

If you are keen to build a career in data analytics or data engineering, it becomes important to understand what their exact responsibilities are and how to develop the required skills if you want to embark on either of the roles.

What does a Data Engineer do?

A data engineer designs, develops, and maintains the systems and infrastructure that make it possible to process, store and analyze large datasets. They oversee the creation and management of data pipelines, maintain databases, verify data quality and merge diverse data sources.

Data engineers collaborate with data scientists, business analysts, and other stakeholders to understand the organization’s data requirements and create data solutions that fulfil their business requirements.

Skills needed to be a Data Engineer

To be a successful data engineer, one needs a diverse range of skills, such as:

  • Strong programming skills: To become a successful data engineer, you must be proficient in at least one programming language, such as Python, Java, or Scala.
  • Database knowledge: You must clearly understand databases, data warehousing, and data modeling. You should be familiar with various data processing and storage technologies like Hadoop, Spark, and NoSQL databases.
  • ETL and data pipeline creation: ETL (Extract, Transfer, Load) tools help get data from different sources and store it in the database for analysts to work on. 
  • Cloud computing skills : A data engineer must have knowledge of cloud computing platforms like AWS, Google Cloud, or Azure.
  • Communication : Data engineers work closely with data analysts, data scientists, and business stakeholders. Communication and teamwork skills are crucial to excel in this field.
