It does not unlock automatically. If your Jem'Hadar is a Gamma Recruit (this applies only to Jem'Hadar who were created in the first several weeks), you should have an item in your inventory which, when used, opens a menu that allows you to claim various rewards based on your progress.
The admiralty slot unlock is one of those rewards.
Once you claim it, your other characters can pick up the same reward from your homeworld Temporal Agent.
