Sites like Indeed, SimplyHired, Craigslist, Dice, etc. let you do advanced searches and then get RSS feeds based on those searches. This also lets you easily filter our garbage like CyberCoders based on keyword.

Getting the data in is easy. Improving the signal to noise ratio requires a bit more work.

Every site lets you do this - I know that. Im asking if there is a site that lets you aggregate a few job boards and get one daily email.

We are working on that for Jobzey.com and have a rough version (about to be pushed live). Were you interested in subscribing to such a service or building something in the space? If subscribe, I would love to chat about some details as we are actively trying to integrate this. Drop me a line at mark [at] jobzey [dot] com
