Virella briefly mentioned it but White Mage is specifically the role of the Padjals who tend to the forest around Gridania (until the Warrior of Light barges in). Padjals are the Hyur/Elezen children selected by the forest's Elementals to receive the power of Succor, then they grow horns and stop aging. The devs have said there are less savory ways to gain Succor, but we don't know what that entails yet.
Dark Knight is specifically the role of Ishgardian vigilantes, those who fight corrupt officials of the Church. Their "Dark" powers aren't the same as casting class's magic as it runs off of emotions. I haven't played their story to completion but as I understand it, using those emotions carries a risk of you being consumed by them, basically losing yourself to the darkness.
As you can see, neither Job is related to the other, nor to Keepers. There's no reason your character couldn't be a person who knows how to use a greatsword and a Conjury cane if you can explain how they trained in both a martial ability and a magical one. (Conjury is said to be easy to pick up, though.)
