If Niles needs a current or past job, he's welcome to come work for Jaeger! Jaeger runs a curio shop called "Leviathan's Claw" but since he can't pronounce it properly everyone just calls the place "Jaeger's". It's been open for around three years, so it could be a past employment opportunity if you've already got something lined up for Niles! Jaeger's in general very Shady, so I feel like he would get along with Niles even if this doesn't work!
