What is a Data Engineer?
A data engineer is responsible for building, managing, and maintaining the systems that collect, store, and transform big data. Without these systems, anyone in a company may find themselves challenged with retrieving data to gain meaningful insights. That’s why a data engineer is a very essential part of a company. They work in the background to ensure data flows smoothly from sources (in raw formats) to destinations (in usable formats for analysis).
Key Responsibilities
Each company can assign slightly distinct responsibilities to data engineers. This depends on the projects they participate in. But generally, their duties revolve around the following tasks:
- Developing Data Architecture: Data engineers create blueprints for data management systems that align with a company’s particular requirements. This often involves choosing the right technologies or tools to process data.
- Creating Data Pipelines: They build reliable pipelines (normally, ETL/ELT) to automate data collection and processing tasks. These pipelines are automated processes that help gather data from different sources, clean it, and make it ready for analysis.
- Optimizing Data Storage: They’re in charge of developing effective storage solutions. This helps store data in a way that increases data extraction speeds while reducing costs.
- Maintaining Data Quality and Security: They ensure data is always accurate, consistent, and complete. They have to, therefore, implement monitoring systems and run constant audits to identify and rectify issues. In addition, they must adopt security solutions (e.g., encryption) to protect information from breaches and unauthorized users.
- Tracking System Performance: They constantly monitor how data systems operate. This helps them make necessary improvements to ensure these systems always work effectively.
- Working with Other Teams: Data engineers have to work hand in hand with data analysts, scientists, and other stakeholders. This enables engineers to understand data requirements and create systems that address the requirements at hand.
Required Skills & Experience
Similarly, each company may have different requirements for a data engineer’s skills and experience in their job descriptions. However, an engineer is often required to have common skills. They often cover technical knowledge, soft skills, and hands-on experience.
- Expertise in Programming Languages: Data engineers need to master programming languages (e.g., Python, SQL, Java, or Scala). These languages help them manipulate and manage data efficiently.
- Familiarity With Big Data Technologies: They must be experienced in using big data technologies (e.g., Hadoop, Spark, or Kafka). These technologies assist them in processing vast amounts of data effectively.
- Cloud Solutions: Presently, most organizations are migrating towards the cloud to save costs and make access easier. So, experience with cloud platforms (AWS, Google Cloud, Azure, etc.) is a bonus.
- Database Management Skills: Data engineers need to be skilled in monitoring database systems, whether SQL or NoSQL databases. Understanding of database management helps them organize, store, and retrieve data effectively.
- Knowledge of Data Warehouses: They must be familiar with data warehousing technologies (such as Snowflake or Amazon Redshift). These techs are essential to develop large-scale, scalable data storage solutions.
- Soft Skills: Data engineers need strong abilities in problem-solving and communication. Why? First, they need robust analytical and critical thinking skills to resolve data-related problems effectively. Moreover, they work closely with other teams and relevant stakeholders. So, they must communicate technical findings well for everyone to understand.
- Educational Background: Some companies require candidates to possess at least a bachelor of science degree in computer science, engineering, applied math, or any data-related field. Other advanced roles may require advanced or additional certifications. However, there are still recruiters who just focus on the skills or experience of candidates.

FAQs
Below are some common questions candidates may ask when learning about the data engineering position. If you want to pursue this career, don’t overlook these questions.
Question 1: Is Data Engineering an In-Demand Job?
The answer is yes. According to the WEF (World Economic Forum) Report released in January 2025, data engineering is one of the most in-demand roles, especially in the IT Services industry. In particular, this profession records a global net growth of 32% from 2025 to 2030. There are many reasons behind the increasing demand for this position:
Booming of Big Data
Companies now can generate data from any source. Especially with the rise of the IoT (Internet of Things) technology like sensors and wearable devices, they can collect large volumes of data in real-time. To store, manage, and process such big data effectively, there’s a growing demand for data engineers.
Need for Data-Driven Decisions in Real Time
Companies across all fields are increasingly depending on data to make informed decisions. Be it to optimize operations, boost customer experiences, or forecast demands, data always plays a core role in strategic decisions. However, without data engineers, data can’t be processed, accessed, and ready for analysis.
Moreover, many companies now require real-time data processing to address specific tasks timely (e.g., suggesting personalized treatment plans). Data engineers play a key role in developing systems that can handle data in real-time.
Shift Towards Cloud Technologies
There’s a growing adoption of cloud platforms like AWS, Azure, or Google Cloud. This has propelled an increasing need for skilled data engineers who can build, deploy, and maintain data systems in cloud environments.
As companies continue to depend on data to improve their strategies, the demand for data engineers remains high. This provides good job opportunities to those with the right expertise and skills.
Question 2: Does a Data Engineer Pay Well?
Data engineering is one of the most lucrative roles. In the United States, a data engineer can earn an average base salary of $125,345 per year. According to our previous article, this position even pays higher than data analysts and data scientists.
Of course, this salary figure can vary depending on different factors.
- Experience Level: Like other roles, the earning of a data engineer increases with experience. Those with less than one year of experience can earn an average of $97,540 a year, while those with more than seven years of experience often make six-figure salaries.
