You should hire for personality characteristics, not knowledge. I'll take anyone who's worked on a weird obscure system and figured it out from first principles over Front End React Dev #8482828 with Opinions on algebraic effects.
It would also be an interesting job, even if off the beaten track.
As a hiring manager, if I saw this on a resume interspersed with various web development work, I would be intrigued.

I'm not sure what personality characteristic are supposed to be in this context. But if you mean skills, then you have a false assumption. NASA and the surrounding industry is not really the environment where they grow boring react devs. For every legacy project like voyager, they have a dozen frontier-projects and other weird obscure jobs where one can gain the same skills, but better, with more potential for further growing. And someone early in their career will naturally choose something with more potential for their future.
