I'm a developer (age 50+) rather than a data scientist and I've been lucky enough to enjoy all my jobs.

Partly I put this down to working at small companies where you have the autonomy to get things done without too much bureaucracy. However if I was put in a situation where I was working in a large organization and felt the job wasn't making the most of my talent, I would do 2 things:

(a) take my best guess of what I could do that was in my power that would have the greatest impact on the bottom line, and spend as much time as possible doing that (this might not have much relation to my job description)

(b) go as far up the management chain as necessary to try and get someone to understand what I was doing and why.

This maybe a naive and optimistic approach but I'd like to think that after you've tried this with a few different employers you'd find somewhere you were properly appreciated.
