The Wikimedia Foundation is looking for a Senior Software Engineer to join the Product Safety and Integrity team and build new security features to protect Wikipedia and our other projects. This is a very hands-on engineering role, working alongside a team of engineers and product managers to design and implement new features to protect and reassure our users and to ensure the platform remains resilient against attacks.

You are a seasoned software engineer with experience building security features in large-scale systems. You understand the importance of testing and documentation, and common pitfalls in developing secure web applications. You have a passion for the WMF mission. We operate in a highly transparent manner, and the work we do touches thousands of editors every day. You will be working primarily on our MediaWiki platform which powers Wikipedia. As a top 10 website, we must meet stringent performance standards while addressing new security challenges such as supporting modern authentication technologies, detecting and preventing platform abuse from bots, and planning and rolling out improvements to our security architecture by defending against emerging threats.

You Are Responsible For:

  • Helping design, develop, and deliver security features, with safety and security in mind
  • Working with other engineering teams to ensure that they make safe and compliant architectural and implementation choices
  • Leading by example in code review, decision-making, and team culture fostering transparency, empathy, and collaboration
  • Developing, reviewing, and deploying security features developed by the Foundation and community members
  • Conducting internal and external security and privacy reviews
  • Performing maintenance and addressing technical debt in security and privacy-critical components
  • Providing support for application security and privacy incidents and operations

Skills And Experience:

  • 5+ years of experience as a software engineer, ideally with focus on security or privacy
  • Ability to work effectively in a modern web application; ours is mostly PHP and JavaScript
  • Deep PHP experience isn’t required if you have enough experience in engineering and back-end web development to learn it and be useful
  • Driving technical quality and operational excellence by defining and reinforcing standards in testing, observability, and system reliability
  • Comfortably and autonomously creating proofs of concept, writing design documents, and breaking down complex projects into actionable tasks to support less experienced team members
  • Experience in developing secure software or security and privacy-related product features
  • A strong interest in working with a talented security team and learning more specialist security skills such as exploiting and mitigating application-level vulnerabilities
  • Ability to explain complex security issues and their implications on privacy and risk to non-technical audiences
  • Sensitivity to the security and privacy challenges faced by participants in a large, international project
  • Experience working in a remote, distributed team

Additionally, We’d Love It If You Have:

  • Experience working on anti-abuse mechanisms, such as detecting bots or coordinated activity
  • Previous experience building security countermeasures against attacks on technologies at the web, backend, and database level
  • Experience finding and fixing security bugs and reviewing code for security gaps
  • A working knowledge of threat modeling, secure design patterns and privacy by design
  • Prior experience with MediaWiki or Wikimedia projects
  • Contributions to open-source software
