What jobs are exciting in the hospital?

I want a job that is thrilling and never gets boring. My favorite subjects are chemistry and physiology. So, I would like to work in a hospital with people. My question is what cool/exciting jobs are there in the hospital besides an MD, possibly in the OR or ER? btw I don't want to be an RN or PA. I think a job as an OR clinical pharmacist specialist is a perfect fit for me. What do you think? Does anyone know more about this job or any other job that I may like? Thanks!
