Take it from someone who works in software, Amazon posting that job means nothing.

There are practically 10 posts about how Amazon is going to start accepting Crypto all based on posting a job for a crypto expert for their payments team.

This could mean nothing more than they want someone to evaluate the market and feasibility. I've been working in the software industry for a long time and have worked on projects for months that were never released. I have also worked on projects that took years to implement.

Amazon is a big enough company they can hire great people and have the resources to move quickly, but don't read too much into this yet.
