The goal is straightforward

make PyPI financially sustainable so it doesn't depend entirely on donations and sponsorships. We launched PyPI organization accounts in 2025 as our first revenue stream, so there's already some groundwork laid. Most of your time goes to shipping features that help sustain PyPI and the PSF. You'll write Python, work with the packaging ecosystem's standards process when new features need upstream changes, and deal with the unglamorous parts: billing integrations, access control edge cases, storage and CDN costs. The tricky part isn't technical. It's figuring out what PyPI can offer to free users as well as organizations. You'll be part of those decisions, which means understanding what commercial tools offer, what enterprises actually need, and how to generate revenue while keeping the PSF’s mission first. PyPI is free infrastructure that millions of people depend on. We have an opportunity to make it more powerful for organizations, which will help sustain the foundation, as well as free users.
