You’ll be part of the small-but-mighty team at the Python Software Foundation, the US non-profit organization working every day to help Python and its community thrive. Most of your days will be time-boxing between day-to-day vulnerability coordination and malware handling work alongside long-term projects like documentation, tool development, and gathering and sharing metrics. Core Responsibilities & Development Triage and remediate vulnerabilities in CPython and related projects in coordination with the Python core team. Remediate malware and supply-chain attacks for projects on the Python Package Index.
