Software Security Engineer

An overview of this role

You will engineer security improvements to the GitLab product as well as building and maintaining the tools we use to detect and prevent abuse on our SaaS platforms. A strong software engineering background with experience in large Ruby/Rails codebases is required. As an engineer on the Trust and Safety team, you will predictively identify abuse patterns and trends and build prevention systems to mitigate abusive users.
