- Write maintainable code that meets our internal standards for a high-scale environment, including tests with every merge request
- Review code within our Code Review Guidelines and respond promptly to contributions from people who don't work for GitLab
- Identify technical debt and propose and implement solutions that improve the team's efficiency
