As far as I know Amazon has opened only one position for business in the field of cryptocurrencies ->
Digital Currency and Blockchain Product Lead.
Bitcoin is not mentioned anywhere, but CBDC and blockchain are mentioned, which probably suggests that they will work on their own cryptocurrency, which means that we should not be overly happy about such a development.
it is not directly related to bitcoin, but this amazon plan has shown amazon's interest in developing new technologies related to blockchain and cryptocurrencies. Just waiting for further developments. Speculation like this often happens and of course the news will continue to grow.
