Each company has different compensation system. For what I know/got: Amazon L6 (Sr SDE) top compensation is at 350k. It doesn't matter that 350k comes from sign-on or performance bonus. Amazon will do the calculation and set up 350k as ceiling for L6. Amazon L7 tops at 600k. Google T4 w/o sign-on is roughly 200k. However, most T4 people have sign on which is additional to 200k. Google T5 is around 300k without sign on. Microsoft L65 is around 280k without sign on.
