Although I've been involved with WordPress for 16-years, I don't specifically foray into the world of core WordPress development all that much, mainly because I'm focused on client work. I'm unclear on the "Contributor" category added to the official WordPress jobs board. And, what a "sponsored Contributor" is.

There's already "Plugin Development" and "Theme Customization," so can someone explain further what would be an example post to the Contributor category on the Jobs board. What is a "sponsored Contributor?"
