Current job sites requires employers to manually enter open positions, and more importantly periodically updating them, a hassle. On the other hand, all companies post their current openings on their own website, usually the "career" section, which one can apply directly by either filling out a form or sending an email.
We need a search engine tailored for jobs.
Implement a web crawler that scans the entire web, and collect information from the "career" section of all companies' web sites, and store them in an indexed database. The update is done automatically by the crawler.
New popular career sites may have been doing this already, simplyhired.com and juju.com.
