Developed by UK-based job search engine Workhound, TwitterJobSearch pulls up Tweets that are only job-related and links to the underlying job posting. With TwitterJobSearch, you search across all of them, and results are ranked by both relevance and by how recently they’ve been posted. A job search for “software engineer” returns 4,838 results, and you can reorder results by geography simply by adding the name of a city to the search.
