My Job title is "Programmer/Analyst" but my job duties are that of IS Analyst as in NOC 2171, Would that be a problem?

Hi My Job Title is “Programmer/Analyst” and it has been for 2 years now. I intend to apply under NOC 2171 as my Job responsibilities/duties match with the NOC 2171 , would the title be a problem? My employer is not willing to change the Title. Also, I have a degree in Biotechnology and i specialize in Computer systems Analyst for Lab Enterprise systems.

That should not be a problem, but make sure the Job duties in the reference letter match NOC 2171.
