About the role
TL;DR

- •As Claude moves from a chat product to an agentic platform, we are defining what identity and access look like when the actor is a human, a service account, or an autonomous agent acting on someone's behalf.
- •Key Responsibilities Own critical, high-traffic systems end to end, from design through rollout, operations, and iteration.
- •Shape the technical strategy for how identity and access work across Anthropic.
- •Design credentials for agents and long-running autonomous workloads.
- •Build a first-class identity model for service accounts and agents.
- •Deepen enterprise integration: login policies and recovery methods, self-service allowlisting.
- •Requirements 8+ years of experience building and operating backend or platform systems at scale, ideally including identity, authentication, authorization, or security-adjacent infrastructure.
- •Experience with OAuth 2.0 and OIDC, SAML, SCIM, JWTs and token exchange, workload identity federation, policy engines, or RBAC models.
- •Deep care for reliability and security, designing for on-call, failure modes, and revocation.
- •Comfortable owning large migrations in live, high-traffic systems.
- •Product-focused approach to platform work, building primitives that are easy for other engineers to adopt correctly.
