Curiosity is a quality, but not a qualification.
For hiring, what you should look for, first and foremost, is competence. Curiosity is not a substitute.

Curiosity is a decent indicator one of the many types of competence that you ought to be assessing: the ability to learn new skills and deal with problems that are outside of their current skill set. Which for most software jobs is rather key skill.
For an analogy, I wouldn't hire a pilot that isn't interested in other planes than what's on their license. What if I want to operate some new models?
Unless I'm looking for someone for a truly specialised role, I would avoid people that stick to only one thing for their entire careers.
