Nice to Have

• Experience with large-scale build tools (Bazel, Buck, Pants, or similar).
• Familiarity with Git internals and repository lifecycle optimization at scale.
• Background in developer productivity or internal platform engineering.
• Contributions to open-source Go or infrastructure projects.
• Exposure to static analysis, security tooling, or automated code review systems.
• Experience in enterprise-scale engineering environments.

This Role Is Likely Not a Fit If
