In the data ecosystem, Data Engineering is the domain that focuses on developing infrastructures that help efficient data collection, processing, and access. A Data Engineer is responsible for constructing the backbone of the data world and should be aware of the must have data engineering skills in 2025.

WeCloudData offers multiple courses in data-related fields like Data Science, Data Engineering, and Machine Learning. We help professionals boost their technical skills and beginners get started with Data and  AI. This blog is all about Data Engineering. Let’s explore the specific skills needed to excel in this field.

What does a Data Engineer do?

Data Engineering is the building block of effective data-driven decisions. It focuses on designing, building, and maintaining infrastructure for data processing and analysis. A data engineer works with databases, ETL pipelines, and different cloud platforms. Data Engineer ensures that data is accessible for analytics and Machine learning modeling.

WeCloudData offers courses on  ETL, Machine learning, and cloud platforms  if you want to learn more about them visit our website.

Must-Have Skills for Data Engineers in 2025

The saying goes “Garbage in, garbage out”.  Data plays a key factor in making a data engineering project successful. Good data engineering skills are essential to ensure that quality data is collected, transformed, and forwarded to the data scientists.

Here are the major skills every data engineer must possess;

ETL & Data Pipeline Development

Extract, Transform, and Load -ETL processes are the backbone of data engineering. Understanding tools like Apache Airflow, and dbt is crucial. Learn more about dbt and ETL  with WeCloudData.

Python for Data Engineering

Python is a golden programming language for data-related tasks. In data engineering, it is also dominant  because of its versatile nature and multiple libraries for data processing. Libraries like Pandas, and PySpark make Python essential for handling structured and unstructured data.

There are many resources to learn Python. WeCloudData offers Python courses for diverse audiences from basic to advanced levels. Explore our website here and learn one of the most demanding skills with us.

SQL

SQL(Structure query language) is important for querying and managing relational databases. SQL is not just a skill, but a cornerstone in the data engineering field. A data engineer should know how to write complex queries and manage large datasets efficiently.

WeCloudData offers a hands-on practice-based course for SQL. Other learning resources include Coursera SQL courses and different SQL tutorials on YouTube.

Scala & Java

Big data frameworks like Apache Spark and Hadoop use Scala and Java programming languages. For a data engineer having practical knowledge of big data frameworks and languages gives an edge in large-scale data processing jobs.

Cloud Services Skills

Cloud computing has become a critical part of data engineering as the use of cloud-based services has increased over the years. Understanding cloud platforms like AWS, Google Cloud, and Azure is essential for working with scalable and distributed data solutions.

Data engineers need cloud computing skills, and you can start developing yours with our Cloud concept courses including  Google Cloud, AWS, Azure

Database & Data Warehousing

Data Engineers have to work with both relational and non-relational databases. So understanding complex data manipulation with  PostgreSQL, MySQL, MongoDB, and Cassandra is essential for data engineers. Along with it, knowledge of data warehousing tools such as Amazon Redshift, Snowflake, and Google BigQuery is also crucial.

Generative AI in Data Engineering

Data engineers are expected to have a basic understanding of machine learning and generative AI techniques with the advancement of AI. Knowledge of ML pipelines and how to integrate AI models into data systems is an added advantage.

Career Opportunities and Salary Insights

As more businesses realize the benefits of making decisions based on data, the demand for data engineers has increased dramatically. According to recent salary reports:

• The estimated total pay for a Data Engineer in the US is $133,723 per year, with an average salary of $106,543 per year.

These numbers can vary based on experience, education, industry, and location. With the continued rise of AI, and big data, both data engineering is expected to see significant growth in the coming years.
