The problem with Data Scientists is that they have been historically overpaid while producing poor quality code. Mostly data janitors who create transformation code using open source libraries, converting from one format / database / stream to another format / database / stream. Then real software engineers look at their code and it’s janky and messed up.

I no longer hire data scientists. I hire recent CS graduates then they cut their teeth on that work because it is very easy, typically low risk, and they can learn the basics of software engineering.
