Perl software development is a seller's market, and that job ad is rubbish and fails to pique interest. It's a bland description with no indication of benefits or salary on offer. In fact, it's even less detailed than the crap Perl job ads that pimps spam me with me on a daily basis. Lack of detail implies there is little good to say about the job. Is that the impression you want to give?
Answer this simple question: Why the bloody hell should I quit my current gig and come and work for you? Then put that answer in the job description.
You are always doing something marginal when the boss drops by your desk.
