"Director" and "Showrunner" are job titles you'd have on your resume. In the case of the showrunner, they're directly involved in day to day stuff. I've heard interviews in which showrunners say their job involves making 500 snap decisions every day: "which fabric swatch should we use? is it worth an extra $80k to film in this location?" that kind of thing. I guess the software equivalent would be a product manager? In Kathleen Kennedy's case, as head of Lucasfilm, she's making big decisions on everything, but likely not micromanaging individual decisions. So, she'd be the CTO or equivalent.
