Ask HN: Jobs for a Language Savant?

I’m not sure if savant is quite the right word, but my son is a language genius. Taught himself to read at 3, started studying greek at 6, etc. We just finished a discussion about Navaho vs Georgian language structures, which I just barely followed along with. He’s studying some sort of microbiology engineering at college simply to get a job, but it’s not where his passion lay. Other than linguistics professor, are there other options in the job market for this sort of talent?
