Ask HN: Who hires interns for compiler/LLVM work?

I am a 3rd year undergrad student and I have an interest in compilers and LLVM, in general. I have been contributing code to open source projects. I am enrolled in a co-op program at the University of Waterloo, but most of the co-ops I see is for general Software Development, SRE or Test/QA. Are there companies out there that hire interns for compilers/LLVM work? If you are one, I'd love to chat with you!
