Find Rust engineers shipping Operating systems

The list above ranks the most-starred public Rust repositories tagged with the Operating systems topic, drawn from the public GitHub graph. Across 73 matching repositories, the contributors are a tight cluster of engineers with both Rust chops and real Operating systems experience.

That overlap is rare. Most Rust engineers haven’t shipped Operating systems, and most Operating systems maintainers don’t write Rust. The people on this list’s contributor graph are the ones who do both.

Refolk turns this list into a search. Ask for Rust Operating systems maintainers hiring” or Rust engineers shipping Operating systems in 2025” and Refolk returns a ranked shortlist with the commits, profiles, and projects behind each name.

How this list is built

Refolk searched GitHub for public Rust repositories tagged with the Operating systems topic, ranked them by stargazer count, and kept those with at least 25 stars. The list refreshes once a day.
