Please be advised, I will not be providing a job description of a Fraud Auditor. Rather, the thought process that is necessary to find the right person, with the right skill set.
I know this is a good technical question, but I do not know if there is a good technical answer. With that said, my suggestion to the CAE’s of the world would be to look for someone with the “Passion for the subject knowledge of fraud risk.” The passion would be for both the science of fraud risk and the passion for the practical application of fraud auditing. I say this because, with any new profession, the person must have the passion to create, build, and polish the fraud audit approach. I am sure that this person will get pushback from the traditional auditor. I know I have.
