Integration with memberships 2 pro, on subdomain

Is it possible to restrict access to jobs and experts according to membership 2 pro level? Membership 2 pro is installed on main domain, job board is on subdomain and I'm using one user table, one wp database.

I need to restrict access to apply for jobs or view board to anyone who is not a paid member, as I also have free memberships.

1) how can I do this, and
2) do I need to install membership 2 on the job board subdomain, even though I'm sharing one user table?

I'm on a very tight deadLine, would appreciate help ASAP, thanks!
