You have crafted a job posting that looks great, sells the job and your company to the prospective applicants, and can be found easily by keyword search. But nobody will see your job listing unless it's advertised somewhere!
Each job board has their own schedule, and your position should appear anywhere from a few hours from creation to a few days. Note that some boards have restrictions and may exclude your post based on their own rules.
