Ok, I happen to love that trope too. Here are a few suggestions:
-I have a lover: She's a lawyer and appears very cold and calculating, almost heartless. But things will change, though she never, ever stops being a badass. The ML is a little weak at start, but he gets stronger by the middle. Highly recommend.
-Ms temper and Nam Jung Gi: Only watched the first episode but the FL is like you want her to be. With a serving of tsudere (at least in the first episode). The ML starts out pretty weak though. She's corporate (beauty industry I believe, and his boss).
-Ab ruk online (Thai Lakorn): the FL is the second in command at a trading firm. She's a strict but fair boss.
-Descendants of the sun: she's a doctor. (Do I need to say that though LOL)
-It's okay that's love: she's a succesful therapist
-Kill me heal me: the same, but her achievements don't really play a role in the story.
-What's wrong with secretary Kim: frighteningly competent secretary.
-The innocent man: corporate, daughter of a Chaebol (does that make her a chaebol?)
-King2hearts: Military woman. She's a huuuge patriot and a badass.
-The queen of office: everything is in the title. The ML is hilarious.
-The good wife: lawyer
-Romantic doctor, teacher Kim: she's a doctor
Hope you find something interesting.
