This article is crafted to help you to get started with an endeavoring journey on “how to become a data engineer”, best job roles in data engineering, data engineering certification, etc. 

First things first, let's get a sound understanding of “what is big data engineer”, is before we dive into knowing “how to become a big data engineer?”

So, Let’s get started!

A Glimpse of Data Engineering and Big Data Engineers

Data engineering is the process of creating and constructing systems that enable users to gather and evaluate unprocessed data from many sources and formats. These technologies enable users to discover useful data applications that firms may employ to succeed. 

Understanding what data engineering is all about understanding the "engineering" component.

According to the U.S. Bureau of Labor Statistics (BLS), “Big data is the gathering and analysis of information that businesses are producing at previously unheard-of scales. A large portion of the data originates from relatively recent technology like social networking, smartphones, and e-commerce.”

Big Data is processed to extract valuable information, which enhances overall performance. Organizations can improve the quality of their products, business choices, and marketing by doing this. And experts in the field of big data help with this task.

The position of a big data engineer is among the top in this industry and going through the data science courses can prepare you for the industry. Professionals that create, maintain, test, and assess a company's big data infrastructure are known as big data engineers. They have fun with big data and put it to use for the development of the company.

What does a Data Engineer Do?

Data engineers create systems that gather, handle and transform unprocessed data into information that data scientists and business analysts may use to evaluate it in a number of contexts. The ultimate objective of a data engineer is to open up data so that businesses can utilize it to assess and improve their performance.

 Following are some typical tasks a data engineer does – 

  • Get datasets that are in line with your company's demands.
  • Create algorithms to turn data into information that can be used to take action.
  • Construct, evaluate, and keep up database pipeline designs
  • Work together with management to comprehend business goals
  • Create fresh data validation techniques and technologies
  • Ensure that data governance and security policies are being followed

Working for smaller businesses frequently entails performing a wider range of data-related duties in a generalist manner. The management of data warehouses, including the loading of warehouses with data and the development of table schemas to monitor where data is kept, is the responsibility of certain larger firms' data engineers.

In the coming sections, we will discuss in-depth on how to become data engineer, but before that let’s go through the top reasons why data engineering fascinates so many aspirants.

How to Become Data Engineer – Step-wise Process

You can begin your data science career path with the right skill set and knowledge. A bachelor's degree in computer science or a closely related subject is the first step toward how to become a data engineer. Acquiring a degree will lay the groundwork for the information you'll need in this rapidly changing sector. To grow your career and open doors to opportunities with higher payouts, think about getting a master's degree.  Follow the step-wise process on how to become a data engineer – 

Step 1: Obtain a Degree

Even entry-level data engineers require a degree of some sort, mainly in computer science, software engineering, physics, or applied math when it comes to how to become a data engineer. In a perfect world, this would also help you acquire the “soft” skills necessary to succeed in the position, in addition to giving you a strong foundation in the fundamentals of software development and/or data.

Step 2: Enroll in Recognized Data Engineering Certification

Maybe you've achieved success in a different industry or have a degree already. If so, taking a recognized online course in a subject like data analytics is another choice. Compared to a full degree, a data engineer certification course is a reasonably cost-effective approach of ‘topping up’ your relevant skill set. You can concentrate on important topics like big data architecture, machine learning, or data analytics, depending on the course you choose. In a thorough and well-designed data engineering certification course by JanBask Training, you will be trained in the latest industry trends and enhance your ability to become a data engineer.

 Step 3: Gain Practical Experience

Data engineering isn't exactly a “first job out of college” type of career, even with a certificate. This is progressively beginning to change as data engineering develops into a specialized discipline. The majority of entry-level data engineering positions require experience, but the definition of “experience” is frequently quite broad, which is advantageous. It's possible that you've previously worked in a data-related position (perhaps as an analyst or in data science), in software development, or as an intern in a related field. Keep your options open when looking on how to become data engineer. 

Step 4: Learn about Your Databases

Make sure your broad understanding of databases and the tools you could use to administer them are up-to-date. It is another basic step on how to become a data engineer. Because they serve as the foundation for bigger infrastructures, databases are an essential component of data engineering.

Step 5: Develop Your Knowledge on Tool Sets

Your work prospects will be much enhanced by expanding your knowledge and skills using various web-based data engineering tools. There are many options available, but a couple to take into account are the cloud architecture from Amazon Web Services, the Apache Cloud stack, and Microsoft's SQL Server Management Studio. Even while you don't have to become an expert in every one of these tools when moving on the path how to become a data engineer, it's still vital that you at least have a fundamental understanding of them.

Step 6: Embrace Work Opportunities

The route to big data engineering is a little tough. Don't give up if your ideal position isn't found immediately. Big data engineering is better viewed as a long-term goal, particularly if you lack experience. Although they may not be directly tied to data, many related careers have steep learning curve.

A great first step toward data engineering is becoming a data analyst. Any position that involves computers or data will help you develop valuable abilities. In the end, data engineers with a breadth of experience gained from a diverse range of positions at various levels are the most productive.

So, this is how to become a data engineer. Follow this process step-by-step to land your dream career.
