Find Julia engineers and maintainers

The list above ranks the most-starred public Julia repositories, drawn from the public GitHub graph. Across 894 Julia repositories in the public graph, the maintainers, top contributors, and recurring committers are a powerful signal for where Julia expertise lives.

Behind every popular Juliaproject is a small group of people who actually shipped it. They’re the Juliaengineers, library authors, and infrastructure builders worth knowing — whether you’re hiring, partnering, or doing technical research.

Refolk turns this list into a search. Ask for Julia maintainers hiring”, “contributors to Julia repos based in Europe”, or “companies whose engineers ship Julia” and Refolk returns a ranked shortlist with the commits, repos, and profiles that earned each person a spot.

How this list is built

Refolk searched GitHub for public repositories whose primary language is Julia, ranked them by stargazer count, and kept those with at least 100 stars. The list refreshes once a day.
