Be prepared for a lot of cleaning. Unless you get to be the head brewer of a larger brewery, big enough that the head brewer doesn't have to clean, that is going to be at least half the job.
Look at home brewing for example. You clean all your utensils, measure and mill the grains, measure the hops, mash, drain, clean the mash tun, boil the wort, pitch the yeast, clean the boil kettle, clean all the utensils. After the ferment you clean all the utensils and fermenter. You clean a keg or bottles, sanitize and transfer. Then clean all the utensils. After the beer is gone you clean the bottles or kegs. And clean beer lines etc. Then you clean up to start all over again.
