Software Engineer III, Product Safety & Integrity

Summary

The Wikimedia Foundation is looking for a software engineer to join the Product Safety and Integrity Team . Engineers at the Wikimedia Foundation get to work on technology that truly makes a global impact — powering Wikipedia and its sister projects, which serve billions of pageviews every month across hundreds of languages. It is a rare opportunity to contribute to one of the largest knowledge-sharing platforms in the world, and to help protect free access to information for everyone, everywhere.

In this role, you will work in a mostly-remote environment. To ensure there are enough opportunities to communicate, the preferred timezone for this candidate will be UTC - UTC+3.

As a software engineer, you will work closely with the team to:

Proactively develop and maintain tools that empower communities to identify, mitigate, and prevent various forms of abuse across Wikimedia projects.

Design privacy-conscious systems that detect behavioral patterns indicative of abuse while minimizing false positives and respecting user anonymity.

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.

Skills and experience:

1+ years related professional experience

Experience building and maintaining large-scale applications

Proficiency in PHP, Javascript or similar

Proficiency in relational databases

Strong foundation in security principles

Experience in driving cross-team objectives
