Responsibilities

• Design, build, and operate the authorization platform - the roles, policies, and access checks that other teams build on top of.
• Improve the speed and reliability of permission checks so they stay fast as usage grows, and set the performance and availability goals that keep them there.
• Build the interfaces, libraries, and tooling that other engineering teams use to easily add access control to their own features, so they can move quickly and safely.
• Lead the migration of older, hard-to-maintain permissions logic onto the modern authorization platform, reducing risk and complexity along the way.
• Raise the technical bar through thoughtful design reviews, pragmatic code review, and clear written proposals that help the team make good decisions together.
• Mentor engineers, share context generously, and partner with product, security, and engineering teams to turn ambiguous access-control needs into simple, well-understood systems.
• Own quality end-to-end - automated testing, controlled rollouts (with feature flags), and observability - so authorization changes ship safely without disrupting the teams that depend on them.
