Compliance Officer
  
A compliance officer is the keeper of rules. Trained in the details, nuances, and minutiae of her industry, the job exists to monitor and enforce the rules inside that industry. Compliance officers roam the hallways in every level of industry. The key notion here is that the compliance officer is like EZ-Off, only you replace "EZ" with "lawyer." If companies don't comply with the rules under which they have agreed to live, then they swing the door wide open for a bunch of ambulance-chasing lawyers from NYC to come and take everything they own.
If you look closely at the T-shirt under the button-down of most compliance officers, you will see their motto: “walk softly and carry a big stick.”
