Founder of REX here, and surprised to see this posted here. Happy to answer any questions, and you can check my comment history for some of my prior posts on REX.
We've had some really great progress that we hope to share in the near future, so stay tuned.
EDIT: Since this article is over a year old, we have made a lot of progress, and have recently taped out our first chip. We haven't officially posted a job opening, but we are very shortly going to be looking for software engineers that would love to work on our architecture. Feel free to shoot me an email if you're interested!
