I think my ideal job would be as a raw material merchant for crafting. Which is kind of what I am now.
Right now I mine material to melt into steel to sell (other materials will come when I get the recipes)
Once its available, I plan to buy up weak weapons to melt down, hides to turn into leather, or any other items that can be 'recycled' into usable material.
If possible, I might work on alchemy or herbalism to make potions. Would love it if I could make up a buy/sell window in game like all the regular merchants have.
