for companies, you really have to go to events like a hackathon and hand out resumes. They usually don’t hire high school students (they don’t even hire early undergrads!). But here is a pretty good research program you should check out:

It is pretty hard to get it and it is more computational biology than computer science. There aren’t a lot of high school research programs out there. I think there is one on IU and SDSC (San Diego Supercomputing Center). For most part, you will have to email professors to find opportunities.
