Senior Software Engineer

Description:

The Wikimedia Foundation is looking for a Senior Software Engineer to join the Product Security team to build new security technologies to protect Wikipedia and our other projects. This is a very hands-on engineering role working alongside our other security team members to design and code new features to protect and reassure our users and to ensure the platform remains resilient against attacks.

YOU ARE ...a smart developer 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 must have a passion for the WMF mission. We do (almost) everything publicly 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 security threats.

You are responsible for:
 

• Help design and build MediaWiki security capabilities
• Review and deploy security features developed by the Foundation and community members
• Work with other development teams to ensure that they make safe architectural and implementation choices
• Perform security maintenance and address technical debt in security-critical components
• Provide support for application security incidents and operations
   

Skills and Experience:
 

• Strong software engineering experience with a focus on security
• Ability to work effectively in a modern, object-oriented PHP code-base
• Experience developing client-side JavaScript
• Experience in developing secure software or security-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
• Patience in explaining security issues and their implications on privacy and risk to non-technical audiences
• Sensitivity to the security challenges faced by participants in a large, international project
• Experience using Linux at the command line for tasks related to web application development and deployment
• Ability to maintain focus when working remotely
