Being a senior at FB/Google/Apple is more equivalent to staff at Amazon and principal almost everywhere else to my understanding. FWIW, before I joined my company (a FAANG), I was an engineering manager/tech lead hybrid. I ended up as a high mid-level in pay band, but being paid at just below the average of the next band up from numbers I've seen around, and currently grew it to more than most at the senior level. I may have taken two steps back on the career ladder, but I've almost tripled my compensation (in large part due to stock performance) from my startup job 3 years ago (which was already pretty high for the market for my background), and I have even more freedom in most aspects with what I get to work on & a very strong management team that supports me.
