From their site: Zubka makes it easy to find and recruit the very best people through personal recommendation. Zubka's technology makes it easy to refer people you know into jobs on our site – and get
rewarded in the process. Now we've made it possible for you to integrate Zubka's job board functionality into your site. You can download our jobs list on a regular basis as an RSS XML file from Zubka. You also have the option to filter it using a parameter list. You can then store this XML in your own database for generation and sorting.
