Data Engineer vs Data Scientist: What’s the Difference?

Data engineers are problem-solvers who are curious and competent and enjoy working with data. Data engineers are part of the team that transforms raw data into useful information for their company.

This article will explain the differences between data engineer, data scientist, and why data engineer is better than data scientist.

What is a Data Engineer?

Data engineers are responsible for establishing and maintaining the infrastructure and data architecture that support an organization’s IT systems. Data engineers need to be skilled in programming, data storage, database management, and system implementation.

What is a Data Scientist?

Data scientists are people who analyze large amounts of data using statistical tools and methods, especially artificial intelligence and machine learning.

Modern technology companies need data scientists to help them determine which ads to show you on Facebook and which TV shows to recommend to Netflix.

Data Engineer vs Data Scientist

Data scientists and data engineers share many similarities in terms of skills and duties. Concentration is the most important distinction.

Data engineers are responsible to develop data-generating infrastructure and architecture. Data scientists are responsible for sophisticated mathematical and statistical analysis of data collected.

Although data scientists are responsible for the infrastructure created and maintained by data engineers, they are not directly accountable.

They can also be internal clients who are responsible for conducting high-level research on the market and business operations to identify patterns and relationships and to act on that data using a variety of advanced technologies.

Data engineers on the other side assist data scientists and analysts by providing infrastructure, tools, and support that can be used to create business solutions.

Data engineers can design systems that deliver solid business data from raw data and create a batch and real-time analyses. They are also responsible for complex analytical projects that focus on collecting, managing, analyzing, and displaying data.

Data engineers are data scientists’ backbone. Data scientists use advanced analytical tools such as R, SPSS, and Hadoop.

Data engineers are responsible for the technical solutions that enable these tools. Data engineers may have access to NoSQL and SQL, MySQL, Cassandra, and other services that help with data organization, such as Cassandra.

Data Engineers’ Responsibilities

Data engineers design, test, maintain and create infrastructures such as databases and large-scale processing technology. A data scientist, on the other hand, is someone who organizes (huge) data.

Although you might not find the word “massage” particularly odd, it just highlights the difference between data scientists and data engineers.

The effort required to convert the data into usable formats will generally be very different between the parties.

Data engineers can deal with raw data that contains human, machine, or instrument errors. Data engineers may deal with the data because it may not be verified or contain suspicious records.

Data engineers are responsible for recommending and sometimes implementing ways to improve data reliability, efficiency, quality, and availability.

They will need to be able to use a variety of languages and tools to connect different systems or search for new data from other networks to turn system-specific codes into useful information that can be used by data scientists.

These two are closely connected by the notion that data engineers must ensure that the architecture is in line with the needs of data scientists and interested parties.

The data engineering group must also create data set procedures to allow data mining, data modeling, and data production to be sent to the data science department.

Data Scientists’ Responsibilities

Data scientists often receive data that has been previously cleaned and manipulated. This data can be fed into advanced analytics tools, machine learning, statistical approaches, and statistical methods to prepare data for predictive and descriptive modeling.

They will need to do extensive industry and business research and utilize large amounts of data from both internal and external sources to create models. Data exploration and examination can be used to discover hidden patterns.

Once the data scientists have finished their analysis, they must present a clear record to key stakeholders. After they have accepted the results, they must automate the process so that business stakeholders can access the insights regularly, monthly, or annually.

To be able to manage the data and make business-critical decisions, both sides must work together. The data engineer will be responsible for database systems, APIs, and technologies for ETL, as well data modeling and setting up data warehouse options.

However, the data scientist must have a solid understanding of stats, arithmetic, and machine learning to create predictive models.

Data scientists must have a good understanding of distributed computing. They will need access to data that has been analyzed by the data engineering team.

However, they will also need to communicate with business stakeholders. This requires a strong emphasis on narrative and visualization.


Data engineers are highly sought after, in comparison to other data-driven occupations. This is in some ways a positive step for the entire field.

Machine learning was popularized 5-8 years ago by businesses who realized they needed data classifiers. Frameworks like Tensorflow or PyTorch became extremely popular and made deep learning and machine learning more accessible to the public.

This led to data modeling skills becoming more common. Data issues are the main problem in helping organizations implement machine learning and modeling ideas into production.
