Sustainability Engineer, PyPI

Apply Now
The Python Software Foundation (PSF) is hiring a contract Sustainability Engineer, PyPI reporting to the PSF's Director of Engineering. The mission of the Python Software Foundation is to promote, protect, and advance the Python programming language, and to support and facilitate the growth of a diverse and international community of Python programmers. In support of our mission, the PSF manages the infrastructure that provides resources and downloads on python.org, documentation on docs.python.org, packages on pypi.org, and more.
 

Overview

This role will be focused on building features in Warehouse, PyPI's codebase. 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.
