Compiler, Language and Runtime Teams
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.
Scope
Contributing
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.
