Need suggestion on job change

Hello guys,

I have recently been selected for one of the MNC as NOC Engineer (L1) and meanwhile my friend is asking me to join his organization as post sales engineer (deployment). Currently I'm working as post sales engineer. I deploy firewalls, routers, switches and access points.

Should I join as NOC Engineer or again change the organization with same position as Post sales engineer (Deployments of devices )?

Your inputs will be valuable.

Thanks
