Mi'kael is a pretty simple guy. Before everything went wrong for him, he pretty much would've wanted a job that could keep him as close as possible to his love interest, Aeris. A lover boy at heart you could say, lol.
Since he's pretty much an Heir to the Seraphane, who have enough resources and funds to not worry about the food they eat or the clothes they wear, even the simplest Corporate Job would be enough for him.
He's a simple man, never asks for much, and wants to enjoy life as much as possible.
But after the events he went through, he became a changed man. Smiling became harder for him, and he constantly feared for the fact that he'd lose the ones he comes to love.
Now however, the Job he'd most likely take would be one would be one where he could take his mind off of the things he's been through.
I'd probably say, a primary school teacher. During one of the events of the story, he sacrificed his own cover to protect a child from harm. He values innocence greatly because he lost his own at a very young age. Plus he's very good with kids. Despite his dark and brooding personality, he never shows that side to the little ones. He acts almost like how he used to be.
