Zapier is building the foundational systems that enable users and services to securely interact across our platform. As a Senior Fullstack Engineer on the Identity Platform team, you’ll design and scale the systems that define and enforce access across Zapier — from permissions and policies to OAuth/JWT infrastructure and service-to-service authentication.
This is a high-impact platform role: you’ll shape how access is modeled, enforced, and scaled across Zapier, establishing consistent patterns that power secure interactions across a large, distributed system. The systems you build will be used by many teams and services, forming the foundation for how authentication and authorization work across the company.
