MASSIVELY depends on your definition of "really good." I can't think of ONE among my colleagues that doesn't saddle its pilots with "extra duties," and that includes the "legendary" Coca-Cola flight department.

I was paid quite a bit when I managed and flew a company's jet. Salaries didn't get THAT much higher, and every day, year after year, it was rather strongly implied (in multiple areas of work) that I was expected to eat, sleep, and breathe my job.

This is pretty much the only place in aviation where you needn't worry about being tasked with anything but operating aircraft.

"Moderately good" corporate jobs:

Let's say you LOVE, say...being asked to help turn wrenches with mechanics after having to find a rental car to retrieve the part you you had to hunt for on Partsbase (AFTER having worked a "duty day" that's left you desolated); these jobs are ones you've snagged via a rather long investment in networking over the course of several training cycles at SimuFlite...most likely...or after being invited to lunch with the guys that X-Corp forces to come to their hangar five days a week just down the way from the Signature ramp.

In nearly EVERY case, not having the type rating for the aircraft they operate promptly removes you from all consideration.
