Pros
Benefits, work/life balance, work from home privileges (note: not all teams have this), very strong engineering culture, smart engineers and capable managers, relatively fair review system, tries to be client driven, strong onboarding plan (new hire training, mentors), innovation encouraged, company will support you resource-wise in "getting things done", relatively little bureaucracy due to PD / engineering division of labor, patience with new hires, excellent in-house managerial training, decent social atmosphere (you have to be here for a while to appreciate it).
Kontras
Rigid promotion requirements hinder top performers from faster recognition (for some teams, not all), pay is average to below average for the financial software industry in NYC, in-house technology-oriented training not at the level of managerial training, an initiative needs to be developed to help PDs and engineers collaborate better (I'm serious about this), working in the financial software domain means you don't really understand the end-user (unless you are a banker or money manager), some teams have pager / on call duties, specialization means cross-team moves are less likely.
