You can sync your job posting directly with Monster.com

To create a Monster posting navigate to the Jobs page and select the existing job that you would like to share.

On the right-hand side of the page, find the Monster section.

If you do not already have an existing Monster account, selecting the Post Now button will bring you to a payment screen.

Either select your existing billing profile or enter a new set of billing information, including your payment information and your billing address, and select Post My Job.

If you already have a Monster account, you can log in by selecting the Existing Monster Customer link, and enter your existing Monster username and password.

Monster postings connect to companies by Company name.   In most cases, these will not be posted in real time but will be updated once a day when Monster retrieves the information.
