Awesome! You're about to become a GitLab UX Researcher! Make sure you've checked out our handbook beforehand, so you get a feeling of how we work at GitLab. Below you'll find everything you need to started. If something is missing, add it (as goes with everything at GitLab)!
We have two main GitLab instances, as explained in the general onboarding.
Please see the UX department page in the handbook.
Also see the basics of GitLab development in the developer onboarding.
As design can be subjective, discussion can heat up. Always try to be direct, but kind. Try to give your best reasoning for your choices and evaluate everyone's opinions. Come up with a solution instead of discussing endlessly. If you think additional perspective is needed, mention a fellow UX Designer in the issue.
