If you saw the user 'shairyar', he works at Travis based on linkedin profile page (but not based on github profile page). I was confused as well when I saw that.
It's very possible (likely) this is all fine, but done in a way that feels strange/fishy. I haven't even gotten an email from travis. They must be in fire-extinguishing mode.
I see he now has access to three travis-ci organisations on GitHub.
