Careers at Facebook

The London Security Infrastructure team builds infrastructure that makes it easier to write secure code at Facebook. Our goal is to make the site safer while actually increasing other engineers' productivity. We create libraries that provide common services like authentication and encryption, and we work with teams to integrate those libraries into their products. We use a combination of static and dynamic analysis to identify common security problems such as XSS and SQL injection. In the London office, we tend to focus on the security of our backend services rather than the frontend codebase, but we're willing to work on anything that will make the site safer.
