A listing of compiler, language and runtime teams for people looking for jobs in this area. My motivation for curating this is in this blog post.
-
Teams that work on language implementations, compilers for languages, language runtimes, static analysis, etc. This includes things like:
- Database query compilers
- HDL & Synthesis Compilers
I want to err on the side of openness! The field is broad, and I don't want to be too close-minded here.
-
I generally want evidence that a company has hired at some point in the past or will in the future (which excludes some boutique firms & early stage startups).
Please contribute: Pass on projects, teams, companies I've missed.
Feel free to spruce up the description of the work for teams you know about! Many of these are simply stubs
I generally link to a company's Careers/Job's page rather than linking to specific jobs -- these links have a longer lifespan than just the straight up link to a job.
