The OP is being kind of cagey about what their role is. Nearly everyone at Amazon who does what we would generally be considered a primarily dev role is either an SDE (Software Development Engineer) or a WDE (Web Development Engineer). Are you a support engineer, by chance?

As for salary negotiations, the best piece of advice I got was to never say a number. You really don't have to, you can just keep saying some variation of "industry standard", their median salary numbers on Glassdoor, etc.

This is true for Amazon specifically: I never told them a number despite being asked by several different recruiters, and the offer I ended getting was slightly above their average. If you want more than that there may be some other technique involved, but if you're more concerned about being undercompensated, definitely don't get tied to any number.
