Prime Brokerage/Electronic Trading (S&T) vs Structured Finance (IBD/WM) exit opps?

I am starting at a BB as a s&t graduate analyst and I want to hear out your opinions on the team that I will be joining. Apparently, my team does a hybrid role of prime brokerage and electronic trading, which could be interesting and meaningful, but one thing that I am concerned about is pigeonholing myself into a "non-market" role. The role seems to be very technology based, and does not involve dealing much with the "market", and I am worried if this would limit my exit opp in the future.

I currently have other offer from a BB at its structured finance team in IBD and I am curious on what you guys think on both jobs and their exit opps.
