Role Overview

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.

The Trust and Safety team both maintains core abuse prevention platforms as well as cross functionally builds customer safety mechanisms on GitLab, such as the introduction of Compromised Password Detection for GitLab.com.

This role is an ideal fit for candidates with software engineering backgrounds interested in moving into security engineering. Formal security engineering experience is not a requirement for this role.
