Continuously adapt abuse detection and mitigation strategies in response to changes in browser privacy standards, networking protocols, and platform architecture
Collaborate cross-functionally with product managers, designers, and researchers to create holistic, human-centered solutions that balance safety and freedom
Write resilient, maintainable systems and high-quality code with a focus on long-term sustainability
Implement observability to maintain high levels of quality and system stability
Instrument and measure the impact of anti-abuse across Wikimedia projects
Requirements:
4+ years related professional experience
Experience building and maintaining large-scale applications
Proficiency in PHP, Javascript and relational databases
Strong foundation in security principles
Experience in driving cross-teams objectives
Experience in driving user and product impact
Nice to have:
Familiarity with abuse fighting or security concerns
A history of open source contributions
