In terms of time on/time off schedules, you can find that with many hospitalist gigs (which you get to following an internal medicine or peds residency) which will often have blocks of time on followed by blocks of time off. Ditto for Emergency Medicine (its own residency) and possibly some ICU docs (fellowship after either IM or peds).
This probably isn't exactly what you're looking for, but there are several nonclinical jobs out there too if you really want it in areas like pharma. There would be lots of travel, which sounds like it may be of interest to you, but you wouldn't really be taking care of patients.
