Who are Data Engineers?
A data engineer is a qualified individual whose job responsibility includes creating, analysing and implementing data for operational uses.
There are particular tasks that are specially taken care of by these data engineers as they are skilled enough to handle these tasks exceptionally.
Tasks can vary from companies to companies and organizations to organizations, however, the work they perform is very much similar.
The tasks would involve establishing data pipelines to gather information using different sources or systems, integrate them and consolidate them and even cleansing data.
Once all these tasks are performed, they have to structure everything all together for any user to utilize the information from a single platform or application.
Data Engineer’s roles and responsibilities
The data engineers are usually a member of the analytics team who provides readily processed data to the scientists or analysts, who would then just run queries using the tools that these engineers designed.
For them, the work should be done within a few clicks while data engineers are the ones who perform the entire background work sitting in their respective computer systems.
Mostly the teams who hire these data engineers are the data mining teams that have extensive manual work. In most of the cases, these engineers also are employed in business units that require technical assistance and advancements to reduce the manual work.
Apart from the data mining teams, the division who extensively hire these data engineers is the operations division in every organization.
The Expectation of every Data Engineer
These engineers possess the capability to work on both structured as well as unstructured data sets because of their technical expertise and interests.
Their knowledge about the data architecture or applications is exceptionally well versed and outperforms from the usual data analysts.
The expectation from every data engineer is to have a basic background and fundamental knowledge about Python, SQL, macros, Java, C Language in computers, etc.
They also need to have an adequate understanding about the extraction of data from databases, the transformation of tools, APIs to create and manage any data
integrations, as well as providing simplified accesses to the users with built data sets to make their jobs easier.

Data Engineer Skill-sets
Data engineers are often known as the warehouse of skillsets. They have a lot of skills which include patience, being the key factor to learn these coding languages and execute them with ease. Apart from this, they should have the presence of mind and common sense which are also necessary for them to build their future. Other skills that they should have are:
– Tools of data architecture – This is the key skill that every data engineer needs as they are connected with the world of analytics infrastructure and several debugging related work. These fields usually require skills such as predictability, architecture-oriented, programming specialists, good with numbers and codes, etc.
– In-depth SQL Knowledge – Data engineers are required to understand the concept of computer language, fundamental and should be thorough in the SQL (Structured Query Language). They should know the basics of database management, SQL and macros in order to perform any operational activities throughout their life as they start working. Similarly, they can opt for gathering knowledge about Python, Hadoop and etc. which should be an added advantage for them to choose the best career paths.
– Data warehouse and ETL tools – Data warehousing is the key element and the skill that every data engineer should have. Data warehousing knowledge is essential as most of the engineers would deal with data stored in the respective databases in their day to day jobs and would face issues if they don’t have a basic understanding about the warehouse structure.
At the same time, data storage and the extraction of data from their respective databases are vital to understanding where they can apply this data warehouse knowledge. So, if you are planning to work in this field, you should definitely be confident with the knowledge you have on data warehouse programming or database understanding.
- Coding – This is the final and most important skillset that every programmer must have sufficient knowledge and expertise. Coding is the solution that every data engineer should be familiar with. As these data engineers deal in codes or bugs on a daily basis, this is the most common thing everyone expects from them to have expertise on. Statistical knowledge, machine learning, data modelling, operating system knowledge, command programming are few other expectations from the organization’s end that they want every data engineer to have a basic and fundamental knowledge.
What is the average salary of a Data Engineer?
Salaries are the hot topic every data engineer wants to talk about. Compensation is the key factor why every data engineer chooses this field to work.
Nonetheless, the payor compensation is quite high when compared to other sector jobs and quite often based on an individual’s talent and knowledge also.
The salary of a fresher data engineer ranges between $110,000 to $145,000 depending on the organization. It actually varies from company to company as well as organization to organization.
