I'm not familiar with the current job market (There is a lot of uncertainty throughout all of the US hiring departments in all fields right now), but it certainly wasn't that hard a couple of years ago.
Compilers are just programs like anything else. All the compiler developers I know were trained up by working on compilers. Just like people writing B2B ecommerce software learned how to do so by working on B2B e-commerce software and embedded software developers learned how to do so by working on embedded software.
Heck, a typical CS degree probably covers more of the basics for compilers than B2B ecommerce software or embedded software!
