Meta Podcast Dives Into Python at Scale
Python is a cornerstone of Meta’s infrastructure. The language powers Instagram’s backend, plays a significant role in the company’s configuration systems, and underpins much of its AI work—including contributions Meta made to Python 3.12.
In the latest episode of the Meta Tech Podcast, host Pascal Hartig sits down with Amethyst Reese, a production engineer at Meta, to explore the company’s relationship with the language. The conversation covers how Meta’s Python Foundation Team works to improve developer experience across the company, the inner workings of Fixit 2—Meta’s recently open-sourced auto-fixing linter framework—and what the production engineer role actually involves day-to-day.
Reese also authored a companion blog post, "Fixit 2: Meta’s next-generation auto-fixing linter," which digs deeper into the technical details of the tool.
The episode is available now on Apple Podcasts, Google Podcasts, Spotify, PocketCasts, Overcast, and Castro. Meta Tech Podcast highlights engineering work at every level, from low-level frameworks to end-user features.
