This is also complicated because the Senior title at Amazon compares to L5 or lower band L6 at G/FB. So your peak Senior at Amazon should be compared to the compensation of a middling L6, which will usually start with a 4.
Perhaps at Principal and beyond the stock grants grow quickly enough to overcome the deficit, I honestly don't know. But I know they don't at Senior.
Looking at SF offers (to avoid the price differential between bay/Seattle), the median seems to be 300-350K for, with a few offers at like 450K and then 2 at ~650 (also some data entry errors like a 300K signing bonus).
The 650 offers are matched by FB/G L6 offers, and the 450K are high L5/low L6 at G/FB. 330 is approximately the floor for a G L5, and new hire offers will be higher due to the relatively larger sign on grants. Like I said, perhaps for peak performers the Amazon grants are larger, but they're not consistently beating G/FB, they're maybe matching.
Its also difficult to tell because the data in levels.fyi doesn't match my understanding of how amazon's stock refreshes work (or like its difficult to tell). My understanding is that you don't normally get a stock refresh, unless your existing one ran out, or the stock didn't grow "enough" (or, as mentioned, your performance is stellar). So if we're seeing the once-every-few-year-grants at Amazon and comparing to the annual grants at G/FB, that's even more against Amazon, but I could be wrong there. I don't know enough senior people at Amazon (though I do know more junior people at amazon, and the levels.fyi methodology doesn't seem to make a distinction when it asks for data).
> I know of SDE2s making 450k before equity appreciation
Fwiw I'm aware of these kinds of hires at most companies.
I'll admit though that my initial statement, that 350-400K was unreachable for an Amazon Senior was flawed. It is, but mainly because the the level is wider than the comparable level at G/FB.
