Amazon AGI L7 SWE offer — SF office, referral (7 YOE)

Amazon AGI L7 SWE offer out of the SF office — ~7 YOE, master''s, came in through a referral. IC role, with big back-loaded equity plus two years of hefty sign-ons to smooth it out. This is the initial package and I haven''t negotiated yet, so I''m trying to figure out what the ceiling is (I''ve heard this org gives even PhD new-grads close to 1M). Still undecided.
