Amazon compensates for back-loaded vesting with sign-on bonuses split across your first years.

Sign-on is guaranteed cash paid with your regular paycheck. It bridges the gap until RSUs start vesting heavily in year .
If you leave Amazon before completing year , you may owe back a prorated portion of the sign-on. Check the exact clawback terms in your offer letter.
