Capital Janeway in Star Trek Voyager. I like the series, seen it a few times, but Janeway annoys the shit out of me some episodes. Yes it's a science vessel and it makes sense to have a nerd captain, but Picard was a science nerd and never have me issue. Jameway constantly gets involved in engineering and coms projects, to the point where she seems far more qualified to be a yellow shirt instead of a red shirt in many episodes.
Pick a role, captain!

Calling dibs on Wesley Crusher in Star Trek TNG before anyone else can.
