The Data Engineer Role: What They Do and How to Get Started

What does a data engineer do?

The data engineer role is an essential member of any data-driven team. With the current explosion of data-related technologies, data engineers are more in demand than ever before. Data engineers are responsible for designing, building, and maintaining data storage systems, data pipelines, and data processing platforms.

They are also responsible for understanding and interpreting data, managing data security, and developing algorithms and models to help drive insights. As such, data engineers are vital to the success of any organization that wants to make data-driven decisions.

For anyone interested in becoming a data engineer, it’s important to understand the role and its responsibilities, as well as the necessary skills and qualifications. With the right education, experience, and training, you can become a highly sought-after data engineer.

What is a data engineer?

A data engineer is responsible for streamlining data with ETL (Exchange, Transform, and Load) tools. In other words, a data engineer is responsible for taking raw data and making it useful through various modeling and analytics techniques.

Let’s say an e-commerce company wants to better understand its customers’ buying habits. To do so, a data engineer would need sales data, product data, and customer data to identify patterns and trends. A data engineer designs and implements data storage and processing systems.

Once the data has been ingested, cleaned, and transformed, it can be used to drive customer insights and create value for the business. Data engineers play an important role in taking raw data and making it useful, which is crucial to any organization that wants to make data-driven decisions.

Responsibilities of a data engineer

As mentioned above, a data engineer is responsible for taking raw data and making it useful and available to the organization. As such, they have to work with data scientists to understand and interpret data, manage data security, and develop algorithms and models to help drive insights.

Here are some more specific responsibilities of a data engineer:

Designing and implementing data storage systems – A data engineer is responsible for designing and implementing the various data storage systems used by an organization. These systems could be databases, data lakes, data warehouses, etc.
Designing and building data pipelines – A data engineer designs and builds the data pipelines that move data from one system to another. They also make sure that data is secure as it moves from one system to another.
Designing and building data processing platforms – A data engineer designs and builds data processing platforms that help process data. They make sure that data is secure as it is processed.
Interpreting data – A data engineer interprets data to look for potential insights. They also check for accuracy and make sure that the data is correct.
Managing data security – A data engineer manages data security by making sure that sensitive data is only accessible to those who need access to it.
Developing algorithms and models – A data engineer develops models and algorithms to help drive insights from the data. They also make sure that these models are accurate and reliable.

Skills and qualifications needed to become a data engineer

There are many skills and qualifications needed to become a fully-fledged data engineer. While some of the required skills are technical in nature, others are soft skills that will help you work well with others. Here is how you can advance your career in this technical field:

Let’s take a look at the necessary skills and qualifications.

Technical skills – A data engineer must have strong technical skills. Data engineers need to understand how different systems and technologies work so they can effectively implement them. They also need to be able to manage these systems and technologies effectively. For example, a data engineer must understand how databases work so that they can help design and implement them effectively.
Communication skills – Data engineers must be able to work well with others, especially data scientists. They have to be able to understand the data scientists’ requirements and be able to explain the engineers’ findings in a way that the data scientists can understand them. They also need to be able to communicate with other team members effectively so that everyone is on the same page.
Analytical skills – Data engineers have to be able to analyze data to look for potential insights. They have to be able to identify patterns and trends and make sense of seemingly meaningless data. They also have to be able to interpret data accurately and make sure that it is correct.
Mathematical skills – Data engineers have to be able to understand and use mathematical concepts and equations. They have to be able to perform calculations and manipulations and make sense of the results. They also have to be able to interpret statistical concepts and equations and make sure that their models are accurate.

Education and training required to become a data engineer

There are no specific education requirements to become a data engineer. However, most employers prefer to hire data engineers with a degree in computer science or information technology. Other degrees that may be helpful include mathematics, statistics, and software engineering.

The best way to become a data engineer is to get hands-on experience by taking on an introductory data engineering role on a data-driven team. Data engineers are often promoted from data scientist and analyst roles, so it’s a good way to get your foot in the door.

When it comes to training, there are many online courses and certifications relevant to data engineering that can help you get started such as the Data Engineering Nanodegree. There are also certifications that can help you get your foot in the door, such as the IBM Data Engineering Professional Certificate.

How to get started as a data engineer

If you want to get started as a data engineer, you have to get hands-on experience. You can’t become a data engineer just by reading books or taking online courses. Instead, you have to get real-world experience.

You can start by taking online courses on data engineering and getting hands-on training with a couple of projects. As you work on DE-related projects, you will have the opportunity to learn as much as you can and become a fully-fledged data engineer.

Another way to get started as a data engineer is to find an organization that is hiring junior data engineer positions or internships. While you may not have much experience, having the right education and training can go a long way. From there, find an organization that is data-driven and get your foot in the door by getting an engineering role on the team.
