If you're unable to expand on your role, that's fine, but as this is a huge interest of mine, I'm willing to take a shot.
What sort of problems do you attempt to solve? How much risk are you allowed to take? How much return is expected? Is it true that most quants are ungodly intelligent and frequently come from PhDs in science?
The work is mostly very interesting, low-latency java programming, distributed systems, etc on a small highly capable team. 40-50 hours per week.
