Why become a data engineer? Missions, required skills, salaries, perspectives: find out everything you need to know about this job.

In 2011, the term “Data Engineer” becomes common to describe database design and integrate software engineering with data analysis. Thanks to the rise of Big Data, data engineering is a category of software engineering that is now essential to the proper use of data.

The job of data engineer

The work of the data engineer is ahead of the work of the Data Scientist and is part of engineering. It consists of developing tools to handle large volumes of data and make them practical and usable by Data Scientists and Data Analysts.  

More succinctly, Data Scientists can be defined as car drivers whose roads were built by Data Engineers.  Data Engineers are now extremely desirable to corporate recruiters because a Data Scientist is no longer sufficient to study data efficiently and completely: group work must be organized. Thus, the Data Engineer is designated to implement the necessary infrastructure to ensure the correct analysis of data. 

Thus, his work comes before that of the Data Scientist. He focuses on setting up the data pipeline and making sure that others can do their jobs properly by providing the right data architectures and making the data usable for Data Scientists

The job of a data engineer has many faces and typical missions are divided into three parts.

The first will be to store, modify and distribute large volumes of data. Then, the data engineer must develop Machine Learning models adapted to production servers. Finally, he will have to create data processing pipelines.

Be careful though! Not everyone can be a Data Engineer and a 5-year degree in science or a 3-year degree in computer science will be a prerequisite to follow this training. In addition, it will be necessary to have some prerequisites in statistics and linear algebra even if the notions to be mastered in priority remain the methods of programming, algorithms and BDD databases.

According to our survey among Chief Data Officers of CAC 40 companies, the salary of a Junior Data Engineer varies between €45,000 and €50,000 per year and that of a Senior Data Engineer will be €50,000 or even more than €60,000 per year.
