The recruiting and screening of applicants is done through a company called People Scout. Because the position is posted again probably means that there is an additional position open. I highly doubt that the position you applied for is filled yet as it tends to be a fairly slow process. Once People Scout completes their process, they will set up interviews (often initially by phone) and contact a few of your references.
At this point, I'd sit tight and be patient. If you aren't selected, you should receive notification within a few weeks.
Best of luck to you!
