I'm a... jerk of all trades I guess? I do a bunch of different things, the biggest are support and sys admin stuff. I guess it's a devops/support job. So I deal with support in ZD and then do the work in GH. As much as I love ZD, I hate Jira an equal amount. Thankfully I don't need to do much in Jira.

I won't speak for them, but some jobs that might need both are internal IT or some kind of support engineer.
