If you’re interested in any of the following topics, working as a big data engineer could be a good career choice: data, math, analytics, problem-solving, numbers, graphs, charts, and IT.

This article will break down all the critical aspects of being a big data engineer. After reading it, you should have a much better idea of whether or not this career is right for you. 

What is a big data engineer?

A big data engineer is a professional who is responsible for developing, maintaining, testing, analyzing, and evaluating a company's data. Big data refers to extremely large data sets. In the modern economy, it is common for companies to collect large volumes of data throughout the course of conducting their business operations.

When used correctly, big data can be highly beneficial for organizations to help them improve efficiency, profitability, and scalability. However, companies' big data is not helpful unless there is a big data engineer to build systems to collect, maintain, and extract data. So, big data engineers ultimately have the responsibility of helping companies manage their big data. 

Typical job responsibilities

All of the following are typical job responsibilities for big data engineers:

  • Designing and implementing software systems

  • Creating systems for collecting data and for processing that data

  • Using Extract Transform Load operations (the ETL process)

  • Creating data architectures that meet the requirements of the business

  • Researching new methods of obtaining valuable data and improving its quality

  • Creating structured data solutions using various programming languages and tools

  • Mining data from multiple areas to construct efficient business models

  • Collaborating with data analysts, data scientists, and other teams

Big data engineer vs. data scientist

The most significant difference between big data engineers and data scientists is that big data engineers are primarily responsible for building and maintaining the systems and processes that collect and extract data. Data scientists analyze the cleaned data to generate insights, using various predictive models to create meaningful insights.
