Design and scale Zapier's IAM platform: OAuth/JWT, permissions, service-to-service auth
Interview for a Senior Fullstack Engineer role on Zapier's Identity Platform team, owning the systems that model, enforce, and scale access across the company — permissions, OAuth/JWT infrastructure, and service-to-service authentication. Expect deep platform-engineering questions on IAM design (RBAC/ABAC/ReBAC), stable API/versioning discipline, and cross-team influence, since this is a shared platform other teams depend on.
