As an engineering manager who has been in 3 major tech companies here. I would say that's a good offer. I'm going to guess that signing bonus is over two years (pretty typical here), and stock is over 4 years (pretty typical here too). So you're looking at around a ~$250k/year salary. I know some engineering managers that have a higher total comp, but I know many more engineering managers that have a lower total comp. Other things to consider (if you're comparing to bay area) is that total cost of living is much lower here and WA has no state tax.
