What Does A Data Engineer Do?
A data engineer is an IT professional whose primary responsibility is to gather data for analytic or operational use. These software engineers are often in charge of creating data pipelines that connect data from several source systems. They integrate, consolidate, and purify data before structuring it for usage in analytics applications. They want to make data more accessible and maximize their organization’s big data ecosystem.
The quantity of data that an engineer works with varies depending on the business, particularly its size. The larger the organization, the more sophisticated the analytics architecture, and the greater amount of information the engineer will be in charge of. Certain businesses, such as healthcare, retail, and finance, require more data.

What Does A Data Engineer Do? Steps To Get This Job
With the necessary skills and knowledge, you may begin or advance your career in data engineering. Among data engineers, an undergraduate degree in computing or a closely associated field is typical. By earning a degree, you may build the foundation for the knowledge you’ll require in a field that is evolving quickly. Consider earning a master’s degree if you want to enhance your career and have access to possibilities with potential higher income.
You may take a number of different actions in addition to getting a degree to position yourself for success.
1. Improve your data engineering capabilities.
Learn the foundational concepts of the internet of things, coding, and database design to prepare for an occupation in data science.
- Coding: Because this profession demands knowledge of coding languages, you could consider enrolling in classes to further your skills. The most often used programming languages are SQL, Python, NoSQL, R, Java, and Scala.
- Among the most common ways to store data are databases, both related and non-relational. You should be familiar with both types of databases and how they work.
- ETL (extract, transform, and load) solutions are used to transfer data from database and other resources into a single repository, such as a data warehouse. Alooma, Stitch, Xplenty and Talend are examples of common ETL software.
- Data storage: When it comes to large data, not all forms of data should be kept in the same manner. You’ll need to know when to employ a data lake instead of a data warehouse, for example, when you create data solutions for a business.
- Automation and scripting: Working with big data requires automation simply because it is possible for enterprises to gather such vast amounts of data. You must be able to write scripts if you want to automate routine tasks.
- Machine learning: Although data scientists are more interested in machine learning, it might be useful to have a basic understanding of the ideas to better understand the demands of data scientists on your team.
- Big data instruments: Data engineers handle a variety of data types. Large volumes of data must regularly be managed by them. MongoDB, Hadoop, and Kafka are among of the most popular tools and technologies, albeit they vary per business and change frequently.
- Because more companies are moving away from utilizing physical servers and toward cloud services, it is crucial to comprehend cloud computing and cloud storage. Beginners may want to consider taking a course on AWS or Google Cloud.
- Data security: Despite the fact that certain businesses may have specialized information safety teams, numerous information engineers are still charged with handling and storing data in a safe manner to prevent loss or theft.
2. Obtain your certification.
Potential employers may verify your skills with a certification, and studying for a certification test is a great opportunity to advance your knowledge and abilities. Cloudera Certified Professional Data Engineer, IBM Certified Data Engineer, Associate Big Data Engineer and Google Cloud Certified Professional Data Engineer are all available options.
For positions you might wish to apply for, go through some job advertisements. It could be a good idea to start there if you notice that a specific qualification is regularly listed as necessary or advised.
3. Create a portfolio of work involving data engineering.
Given that it allows recruiters, hiring managers, and potential employers to see your skills, a portfolio is typically a key tool in the job-search process.
Using a platform like Wix or Squarespace, you may upload data engineering projects you’ve accomplished on your own or as a requirement for coursework to a portfolio website. A free option to a standalone portfolio website is to upload your work to the Projects area of your LinkedIn profile or to a website like GitHub.
4. Start with a position at the entry level.
Many data engineers start out in entry-level jobs like business intelligence analyst or database administrator. As you gain experience, you might develop new skills and qualify for more specialized roles. See an illustration of a potential learning path with this Coursera Data Engineering Career Learning Path.
Conclusion
Data engineering is a profession that is in demand, delivers a better than average compensation, and has a reasonable amount of job stability, yet what constitutes a “good” career will always be a matter of opinion. Although the U.S. Bureau of Labor Statistics (BLS) predicts that the industry will expand by 8% between 2020 and 2030, providing an additional 13,900 new positions every year, Glassdoor reports that the typical compensation for data engineers is $115,176.
