The data engineer is an engineer who works alongside data analysts, data architects, and data scientists. Data engineers maintain and build data pipelines, they work on warehousing big data in such a manner that makes it more accessible for the people whenever they want to deduce the data. They build a huge reservoir for the data and play an important part in managing and maintaining these reservoirs alongside churning the data out for the various digital activities. Their work often includes developing, testing, constructing, and also maintaining the data storing architecture (such as the database or the large-scale data processing system).

Abilities and Aptitude needed
Big data engineers have extensive coding experience in general purpose and high-level programming languages such as Python, R, SQL, and Scala, as well as extensive knowledge of Java. When you compare different job descriptions for big data engineers, you'll notice that the majority of them are based on knowledge of specific tools and technologies. To create, design, and manage processing systems, a big data engineer must learn multiple frameworks and NoSQL databases. Frameworks for big data processing The type of data analysis performed by frameworks for computing over data in the system can be used to classify them. So we have batch-only Hadoop, stream-only Storm and Samza, and a hybrid Spark/Flink.

Yes, there are internships available for aspiring prominent data engineers. Many companies and organizations offer internship programs where individuals can gain practical experience working with big data technologies, tools, and frameworks, preparing them for future roles in the field.
According to one report, data engineer is the fastest-growing job in technology, with more than a 50% year-over-year increase in the number of open positions. It had seen an 88.3 percent increase in postings over the previous twelve months in 2019. According to another report, demand for data engineers has been increasing since 2016. A company`s data science strategy addresses data infrastructure, data warehousing, data mining, data modelling, data crunching, and metadata management, the majority of which is handled by data engineers.
According to studies, most data science projects fail because data engineers and data scientists are at odds. Many businesses fail to recognise the value of hiring data engineers. While most businesses are beginning to recognise the value of data engineers, a talent shortage is all too real. The demand-supply gap, as well as the soaring value of data engineers, have resulted in high-paying positions for data engineers. According to reports, the number of job openings for data engineers is nearly five times that of data scientists.
Data engineers` demand has begun to outpace that of data scientists by a factor of two. And, in most cases, their average pay is surprisingly high when compared to data scientists. Many organisations pay data engineers 20-30% more than data scientists. Data engineers are quickly becoming the highest-paid talent, and their pay is rising at a rapid pace. Aside from companies focusing on delegating data preparation tasks to data engineers, the fact that most businesses are migrating to the cloud has increased demand for data engineers.
