ETL development lies near the intersection of database design and programming but requires a significantly versatile skillset within both fields. Data everywhere is growing rapidly, and all companies growing with it will need specialists to maintain it.

On the database side, candidates might require knowledge of data modeling principles to prepare a final structure for the processed data, knowledge of algorithms for transformations and performance tuning, and familiarity with multiple solutions for keeping data like RDBMSes, NoSQL databases, and other Big Data solutions.

As for programming, ETL developers may need basic shell or Unix scripting skills for managing file/folder structures; they may equally need to know the basic principles of object-oriented programming in various widespread languages like C#, Python, Java, or Go to be able to get and process data from applications and web services.

Although the ETL developer position can vary widely depending on the technology stack used, there are some common skills absolutely required, like advanced SQL knowledge. The data processed by an ETL developer has to comply with a company’s standards and should meet the needs of end users.
