For what industry and what function(s) are you considering? Your question is very general and has no details.
In aerospace, I can quickly think of unique QA/QC 'career areas' in manufacturing/maintenance/repair/testing of: aircraft, missiles, helicopters, engines, components, accessories, electronics, ground support equipment, chemical processes, paint/finishes, petroleum [fuels, oils/lubricants, solvents]... etc?
NOTE1. There are basic/important specifications/documents and text books on the subject of QA/QC engineering.
