Mismatching job roles in Express entry and PR application

[Kumar21]

Hi,

I have submitted my express entry profile with job role as quality assurance analyst, information systems. and received the invite under Canadian experience class. However, my role on my Canadian work permit is "Engineer". This role is not in the listed job titles for NOC 2171.

Can i change my job role in PR application to "Engineer" now? What all precautions should i take while doing?

Thanks,
kumar
