Companies making CPUs are often looking for compiler engineers, mostly in the backend of course. Intel, AMD, ARM, STMicroelectronics, Kalray for instance. You might be able to find a job at a company working with the RISC-V arch too. You'll probably work on LLVM and/or GCC, or maybe an in-house compiler. I know someone working at one such company after doing a PhD in the area and they are happy. I won't be more precise in public, my email is in my profile.
