I worked on compilers at Microsoft, NVIDIA and there are few jobs for traditional hardware compilers. Some new hardware is being designed though, most fun was new optimizations specific to GPUs different caches such as loop optimizer and rematerialization in register allocator. Then I’ve worked on query optimizers for databases and they’ve got completely different technology and papers. Here one can extend Apache Spark, they give lots of interesting extension points. Also, these days my startup is building parsers in Scala for DSLs and if performance is not critical, I’m loving Packrat parsing in Scala (parser combinators), this is way easier and fun. Interesting tooling can be built in Scala, you can also use Scala macros, get access to Scala compiler AST. This kind of work around data might have applications for more engineers.
