The Wikimedia Foundation is looking for an Application Security Engineer to join the Security team working to help protect Wikipedia and our other projects. You'll be working with other developers and security engineers to create new security features, review the security of other people's code, and help find and fix security bugs before they're exploited.

YOU ARE ...a smart security practitioner with experience building and auditing 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 volunteers can add arbitrary JavaScript to our site. That should both frighten and thrill you.

You will be joining a team responsible for ensuring the security and integrity of applications written in PHP, Python, Ruby, Lua, Perl, JavaScript (Node.js) among others, using both relational and key-value data storage mechanisms. (Don't worry, you don't need to have had experience with all of those technologies.)

As an Application Security Engineer, we’d like you to do these things:

  • Triage and remediate reported security issues
  • Work with Security team members to build and maintain security features
  • Review and deploy features developed by the Foundation and community members
  • Work with other development teams to ensure that they make safe architectural and implementation choices
  • Constantly poke and abuse our software to find bugs before attackers do

We’d like you to have these skills:

The right person is better than the right set of experiences, these are the traits we’ve identified make great additions to our team so far.

  • Two or more years of application security experience, including thorough understanding of issues documented in the OWASP Top Ten and CWE Top 25
  • Strong understanding of modern, object-oriented PHP development
  • Demonstrated ability to exploit and mitigate application-level vulnerabilities
  • Experience conducting software security reviews using a combination of source code inspection, manual testing, and automated scanning
  • Patience in explaining security issues and their implications on privacy to non-technical audiences
  • Sensitivity to the security challenges faced by participants in a large, international project
  • Strong understanding of cryptography as applied to web application security (encryption, hashing, PKI management), including analysis and implementation
  • Strong knowledge of the use of a scripting language for system administration and automation
  • Experience using Linux/Unix at the command line for tasks related to web application development and deployment ("DevOps")
  • Ability to maintain focus when working remotely

And it would be even more awesome if you have this:

In addition to the basic skills needed for being successful these skills could set you apart from the pack!

  • Experience as a contributor in the Wikipedia or Wikimedia project communities
  • Experience contributing to a consensus-based open source project
  • Experience developing, maintaining, or administering authentication systems
  • In-depth experience developing or auditing client-side JavaScript
  • Experience with both relational and NoSQL/key-value data storage mechanisms

About the Wikimedia Foundation

The Wikimedia Foundation is the nonprofit organization that supports Wikipedia, the other Wikimedia free knowledge projects, and our mission of free knowledge for every single person. We help bring new knowledge to people around the world, lower barriers to participation, and make it easier for everyone to share what they know. We do this by keeping the Wikimedia projects fast, secure, and available to all, protecting the values and policies that allow free knowledge projects like Wikipedia to thrive, building new features and tools to make it easy to read, edit, and share from the Wikimedia sites, and by supporting the communities of volunteers who make the projects possible.

At the Foundation, we build technology to help people everywhere access Wikipedia, across devices and in nearly 300 languages. We engineer privacy for our readers and editors so they can safely and securely explore Wikipedia. We create programs and initiatives to make Wikipedia freely available to more people in more parts of the world. We build new tools for the community of editors so they can continue to improve and grow Wikipedia. Roughly a quarter of our budget goes to supporting the community that make the site possible, including through grantmaking programs that enable volunteers and enrich the information on the sites.

The Wikimedia Foundation is an equal opportunity employer, and we encourage people with a diverse range of backgrounds to apply.

Voluntary Self-Identification of Disability

Why are you being asked to complete this form?

Because we do business with the government, we must reach out to, hire, and provide equal opportunity to qualified people with disabilities1. To help us measure how well we are doing, we are asking you to tell us if you have a disability or if you ever had a disability. Completing this form is voluntary, but we hope that you will choose to fill it out. If you are applying for a job, any answer you give will be kept private and will not be used against you in any way.

If you already work for us, your answer will not be used against you in any way. Because a person may become disabled at any time, we are required to ask all of our employees to update their information every five years. You may voluntarily self-identify as having a disability on this form without fear of any punishment because you did not identify as having a disability earlier.

How do I know if I have a disability?

You are considered to have a disability if you have a physical or mental impairment or medical condition that substantially limits a major life activity, or if you have a history or record of such an impairment or medical condition.
