When you unlock a new class, do you unlock it at level 1 or level 15?

Level 1.

The only difference with this is Jobs. When you unlock the Job for a specific class, that Job will be unlocked at Level 30 (as its simply an addition to the main class accessed by equipping an item known as a Soul Stone.) So for example the Job for Paladin has you level Gladiator to Level 30 and Conjurer (your secondary job class) to Level 15. When you complete the Job quest for Paladin and equip the Paladin Soul Stone, your Gladiator will switch to Paladin, and will still be at Level 30. As you level your Job, you're also leveling the main class of the job.
