I currently work (as of 6 months ago) at a company where the software engineering staff is made up almost exclusively of two types of people: 1.) young 20-somethings who were hired right out of college. They do all of the coding and grunt work (for cheap). 2.) A smaller set of 55+ engineers who are coasting into retirement. They do all of the architecture and design work. I was recruited rather aggressively and eventually accepted an offer (I'm definitely being paid on the high side for this area). As a 38 year old, this place is incredibely lonely (I have no "peers"). I have absolutely no idea why they hired me. The "elders", who have been at the company for 20+ years, are hostile, backstabbing and hoard all of the interesting work (and credit) for themselves. My "lead" (not the manager who made the decision to hire me - I never see that person now) seems to be actively sidelining me - I've been assigned nothing but grunt work.
