What Is a Data Engineer? A Guide to This In-Demand Career

Data engineering is the practice of developing large-scale data collection, storage, and analysis systems. It covers a wide range of topics and has uses in almost every business. 

Organisations can gather massive volumes of data, but to ensure that it is in a highly useable shape by reaching data scientists and analysts, they need the right personnel and the right technology.

Working as a data engineer can provide you with the chance to change the world in a world where we'll be producing 463 exabytes every day by 2025, in addition to making the life of data scientists easier. That is one byte followed by 18 zeros of data.

Machine learning and deep learning can prosper with data engineers processing and directing the data.

What does a data engineer do?

A data engineer designs, builds, and maintains the infrastructure to store, process, and analyse data. They work with large data sets to provide data solutions to support business decisions.

A data engineer is responsible for designing, constructing, and managing the systems and processes that enable the storage, processing, and analysis of large amounts of data. This includes creating and maintaining data pipelines, integrating data from various sources, ensuring data quality, and developing systems for data storage and retrieval systems. The goal of a data engineer is to make data accessible and useful for data scientists, analysts, and other organisational stakeholders. The work of a data engineer often involves programming in languages such as Python, SQL, and Java and a good understanding of distributed systems, databases, and cloud computing.
