At my day job we use Ruby with Sorbet to stitch together a large number of data engineering pipelines. It's a good choice since we also often stand up small Rails apps to expose the results from those pipelines, so we can keep everything in one language. The fluent functional approach it enables is pretty nice for that business logic (but I would not want to do it without the gradual typing on top). We do find ourselves glancing over at the Python ecosystem with envy from time to time but overall it has worked pretty well. As I've gotten better with it I find myself reaching for irb for more and more one-off tasks in the shell too.
