What Is a Data Engineer? Salary, Responsibilities, & Roadmap

Data is the brand new oil. But who extracts and refines this oil? Data engineers! Data engineers design and develop systems to convert raw data to high-quality data that will be used for evaluation and modeling.

Step one of any data-centric organization is to assemble data from disparate sources. The information is then transformed into the required format and loaded into the information infrastructure. Data scientists and analysts can then access the information to extract insights and solve business problems. The information engineer leads this whole process. Without data engineers, organizations can be unable to make use of their data effectively, which might result in a lack of business opportunities.

Data engineering is a high-paying profession as well. As per Glassdoor’s estimate, the median data engineer salary is $113,784 per yr in america.

On this blog, we’ll discuss reasons, responsibilities, and the roadmap to becoming a highly expert data engineer, and the way a knowledge engineer differs from a knowledge scientist.

Why Develop into a Data Engineer?

Data engineers are the necessity of the hour. They’re an integral a part of an organization’s data strategy because the rate, volume, and variety with which we’re producing data are increasing rapidly.

By the tip of 2025, greater than 180 zettabytes of information can be created, captured, and consumed. We want data engineers to handle such an enormous amount of raw data. With such high demand, it offers a promising profession in the information ecosystem.

Responsibilities of a Data Engineer

An information engineer’s job is to know the organization’s data requirements and construct systems to offer clean, accessible data. On a day-to-day basis, they perform the next tasks:

  • Designing, constructing, and maintaining the information pipelines
  • Working with data analysts and scientists to higher understand the information requirements
  • Validating data sources and specializing in data quality
  • Ensuring compliance with data regulations

Easy methods to Develop into a Data Engineer?

The roadmap to becoming a knowledge engineer is as follows:

1) Acquiring Relevant Data Engineering Skills

a) Coding

In accordance with an evaluation of 17,000 data engineer job postings, greater than 70% of recruiters seek candidates proficient in Python and SQL. Hence, learning Python and SQL must be step one to becoming a knowledge engineer. Furthermore, familiarity with other programming languages, reminiscent of Scala and Java, can offer you a competitive advantage.

b) ETL (Extract, Transform, Load)

ETL means extracting data from various sources to single storage, transforming it right into a form intended for evaluation, and loading it into a knowledge warehouse. Creating and maintaining ETL pipelines is a knowledge engineer’s responsibility. Hence, learning ETL tools reminiscent of Integrate and Talend is essential for data engineering.

c) Data Storage Systems

Databases are used to store the gathered data. Familiarity with relational, NoSQL, and data lakes as different data storage types is crucial.

d) Big Data Tools

Understanding big data tools reminiscent of Apache Spark, Apache Hadoop, and Apache Hive is essential for becoming a knowledge engineer. These tools are used for processing, storing, and querying large volumes of information.

e) Cloud Computing

Cloud providers reminiscent of AWS (Amazon Web Services) and Microsoft Azure provide scalable computational resources for data storage and processing. Cloud computing certifications can assist you learn and practice the elemental and advanced concepts of assorted cloud platforms.

f) Soft Skills

An information engineer must have good communication skills to collaborate with other team members, including data scientists and data analysts. Creativity and problem-solving might help solve challenges in the information engineering lifecycle.

2) Getting Certification

Certifications enhance credibility and gain your employer’s trust. Data engineering certifications will be acquired from credible educational platforms like Coursera and Udemy. They’ve a high-quality practical curriculum taught by expert educators. But, read course and instructor reviews before registering yourself. You can too visit the LinkedIn profiles of skilled data engineers to seek out out which certifications they’ve acquired. It gives you a greater understanding of which tools or platforms are currently trending within the industry.

3) Constructing Your Data Engineering Portfolio

A portfolio is among the finest metrics to evaluate a candidate’s understanding of the topic. Creating multiple projects related to database design and development can distinguish you from other applicants. Uploading your data engineering project on GitHub and sharing a walkthrough blog post on platforms reminiscent of LinkedIn or Medium is a vital step to showcasing your data skills.

4) Securing an Entry-Level Data Engineering Job

Most often, data engineering is just not an entry-level position. Getting an entry-level job as a knowledge analyst will be start. As you gain more experience and skills, you possibly can work up to a knowledge engineer position.

Major Differences Between a Data Engineer & a Data Scientist

Although there are some similarities between the abilities and tools utilized by data scientists and data engineers, there are some distinct differences between them that are as follows:

Parameter Data Engineer Data Scientist
Responsibilities Making data infrastructures (data warehouses, data lakes, etc.) for data evaluation is the important thing responsibility of a knowledge engineer An information scientist is answerable for finding hidden patterns, constructing models, and making predictions on unseen data
Expertise Expertise in database design and ETL processes using Python, SQL, and Java Proficient in data visualization, statistical evaluation, and machine learning using Python or R
Tools SQL Databases, MongoDB, Apache Spark, Apache Hadoop, and Cloud Platforms (AWS, GCP, etc.) Pandas, Scikit-Learn, Tableau, PyTorch/TensorFlow, and Cloud Platforms
End Goal To supply high-quality, accessible data Solve complex business problems and help firms make data-driven decisions


Data engineer comes seventh in Glassdoor’s 50 Best Jobs in America for 2022. As big data roles within the data-centric organization get clearer, the demand for data engineers will proceed to extend.
