Need Suggestion before joining a company

Question

Hello to all members as well as mentors,

 

I need a suggestion before joining a company. Currently I am working in an MVC as Senior Software Engineer. I am selected in another big company with the Role as Business Process Representative (they have mentioned that its a mixed kind of Development, Testing as well as Support kind of role). As I have never heard about this position, Is it okay to join that company with the mentioned Position. Does it will impact my career in the IT Industry. I have around 5 years of experience in IT Development as .Net Developer. Please suggest as I am confused whether I should join or not.

 

Thanks in advance
