If your J1 visa is not subject to the two year HRR, then that rule doesn't affect you. The only issue would be whether you could adjust your status within the U.S. before you have to depart due to going out of J1 status, or if you would obtain the E2 visa after returning to your home country.
If your prospective employer believes that you have some form of duty to your nation of origin, even though you're not subject to the HRR, and won't hire you on that basis, that's not an immigration law issue -- that's a matter of your prospective employee's policy preferences.
