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. OverviewThis 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.Core ResponsibilitiesBuild and ship features in Warehouse, PyPI's codebaseBilling integrations, access control, storage and CDN workWrite Python, review PRs, ship user-facing changesCoordinate with the Infrastructure Engineer on deployment, scaling, and operational concernsCollaborate with PSF and PyPI security engineers on security-related features and concernsWork closely with the PyPI Support Specialist to address PyPI Organizations, user-reported security concerns and escalate issues appropriatelyInterface with PyPI stakeholders about user and community needs Occasional on-call responsibilities, shared with the Engineering team as it relates to PyPIProduct WorkHelp decide what PyPI offers to free users and organizationsResearch what commercial offerings provide and where PyPI fitsTalk to enterprise users and translate their needs into features worth buildingBalance revenue goals with PyPI's mission as free infrastructureStandards & EcosystemWork with the packaging ecosystem's standards process when features need upstream changesCoordinate with Packaging Council and other packaging stakeholdersQualificationsSolid Python experience, comfort with web frameworks, and enough frontend knowledge to ship user-facing features end-to-end. Familiarity with Python packaging and infrastructure concerns like object storage and CDN architecture. Product instincts help since you'll talk to enterprise users and translate their problems into features worth building. Experience working with open source communities is a plus.Required: Proficiency with Python web frameworks, base understanding of HTML/CSS/JavaScript, software testing.Desired: Proficiency with PostgreSQL, proficiency in HTML/CSS/JavaScript, and the Pyramid web framework, Python 3.14+, Pytest, object storageDetailsLocation: Global remoteCompensation: $75-$180K (Based on experience and local employment package norms.
