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.

In Scope: Teams that work on language implementations, compilers for languages, language runtimes, static analysis, etc.

Please contribute: Pass on projects, teams, companies I've missed!

As far as things are known, these companies offer remote work opportunities.

These companies are known to have offered internships or co-ops in compiler, languages and runtimes.

Derived from job postings or other knowledge, this is where the team works. Definitely not comprehensive!
