The GitHub Governance team is one of the highest-leverage teams in ETS. It decides and operationalizes how ten thousand Nubankers interact with GitHub how repositories are governed how access is granted and revoked how vulnerabilities are surfaced and triaged and how the platform serves as the substrate for AI-assisted development at Nubank. The teams mandate touches every engineer in the company and every InfoSec IAM and Datasec partner that depends on the platform.

The team is currently four people holding the platforms active mandate: KPMG audit obligations EMU (Enterprise Managed Users) migration rollouts including Copilot Code Review vibe-coding profile design the inactivity-rule mechanism and IP control work tied to the AI-First posture.
