I was told it's mostly AFT, some AWS teams in Austin. I'd avoid Amazon like a plague.
Heh. Think I know who you are :)
Fulfillment technology, supply chain optimization, Amazon flex technology, amazon business, navigation/gateway(work on home page/ machine learning), video advertising, devices, silicon optimization, FLASH - finanacial software team, lumberyard, AWS (technical account managers) these are largest I can think of. Will still be adding more next year.
They are part of Lumberyard. So game development tools.
