Is there a point in joining Retire ReadyNJ? Job will set you up with the default Roth contribution and investment options. 3% of your total pay (wages before taxes and other deductions) will be invested in a Capital Preservation Option to start, and after 30 days will be moved to a target date retirement fund based on the expected year of your retirement at age 65. Customize your savings choices and account. You have the power to change your contribution levels, investment options, and beneficiaries. Opt out. Not ready to save just yet? Participation in RetireReady NJ is completely voluntary, and you can opt out and back in at any time.

From what I saw its a regular roth IRA.
