Pros
One of the pros of working here is that you will learn a keen sense of what it is to run a technology division of a Tier 1 communications company, using the absolutely bare minimum of resources. I've often heard about how painfully under resourced the Russian space program used to be, but I'm rather certain that if we brought a Russian tech worker to this company, they would say things might be bad in Russia, but not this bad :) Bottom line is this - where the main corporation may or may not be totally healthy (and I have no idea on the status of this) - my position was part of the organization which at this point is kind of like a ghost ship. Nearly all experts have left the company over the past few years, and they're not being replaced by new ones. Where the lack of leadership is obviously a bad thing, for my case it did bring with it a bunch of flexibility in terms of vacation days, working from home, etc and I was definitely appreciative of that :)
Cons
Salaries are 20-30% under market average, in some cases it's even less than that. Where there aren't really many qualified leaders at the upper level, the managers of the various Technology teams try, but can only accomplish so much as they don't really have the backing and full support of the mother ship.
