I'd like to know any better ways to casually describe a back/middle office job responsibility when briefly introducing myself. The situation is when you just state your position in short to someone (for 10-15 sec.) and you don't need to explain what you do in detail at that time.
I often say like "I'm at a middle-office position. My job is mainly to support the front office team." But, I know it sounds immature.
The actual job description is very near to the one in the link below. I'd like to know the natural and elegant way to describe those in short. https://www.greatsampleresume.com/job-responsibilities/middle-office-analyst-responsibilities/?amp
