Dirty IT job No. 3: Enterprise espionage engineer (black ops)

Seeking slippery individuals comfortable with lying, cheating, stealing, breaking, and entering for penetration testing of enterprise networks. Requirements include familiarity with hacking, malware, and forgery; must be able to plausibly impersonate a pest control specialist or a fire marshal. Please submit rap sheet along with resume.

Social engineer, con artist, penetration tester, or white hat hacker -- whatever you call it, Jim Stickley has a dirty job that actually sounds like fun. As VP of engineering and CTO of TraceSecurity in Baton Rouge, La., Stickley gets to talk his way into a client's offices, sneak into their datacenters, make off with the company's vitals, then come back later to show them where their internal security broke down.
