As someone who had an internship coding an working on circuits in high school, I can say that it was one of the best experiences of my high school career. I was fortunate enough to have channels in my community to facilitate landing the gig but I worked there for 9 months and learned a tremendous amount.

You can always try cold calling a recruiter but typically positions for kids in high school are exceptions and so won't be advertised.
