Key Data Engineer Skills

Key Data Engineer Skills

If you wish to become a successful data engineer, you must possess a specific set of skills. This includes being able to assess the potential of a dataset and create a plan to analyze it. However, you need to know certain technologies to complete these tasks.

Below are some of the critical skills that you should possess to become a successful data engineer.

Database Systems

A data engineer is expected to work with data that can be structured or unstructured. If structured data is encountered, one of the most basic ways to store it is in a database. Therefore, you should have good knowledge of popular database systems such as SQL or MongoDB to store and use structured data faster.

Distributed Systems

More often than not, data engineering requires handling vast tracts of data. It is often wise to break this down into decentralized processing via distributed systems. Apache Spark and Hadoop are two of the most popular distributed data processing technologies. You need to be familiar with both of these to adopt any solution to solve problems.

Machine Learning

Once you have data at hand, you are required to draw conclusions and insights from it. Multiple tools can help you draw basic statistical insights, but there are times when the predictive analysis is helpful. Machine learning can help you analyze data trends and provide insights that are not directly offered by the given data.

Data Engineer Salary and Job Outlook

According to the Bureau of Labor Statistics (BLS), employment opportunities in computer-related fields will increase by 15 percent by 2029, which is much faster than the average projected growth rate. This means that data engineering and other related careers will see significant job demand and good growth in this decade.

PayScale suggests that data engineers earn an average salary of $92,407 per year. This is a great number, and it can get even higher if you have more experience and education.
