This is an anecdote - plenty of firms are using Scala in their data engineering stacks and it's a great tool for the job.
While maybe not strictly necessary per se, it's a great way to get a foot in the door, and provides a great way to foster advanced type systems and functional programming (I personally find it to be a really fun language to write in to boot).
