## About the Role

* Professional Experience: 5-8 years building and operating production systems at scale.
 * Identity Domain Knowledge: Working knowledge of identity protocols and models (OAuth 2.0, OIDC, SAML, SCIM, RBAC/ABAC, and session management, etc.). Hands-on experience implementing identity protocols or fine-grained authorization systems, RBAC, ABAC, relationship-based access control, or policy engines (such as Cedar), in production.

 * API Design: Experience designing and building REST APIs: routing, authentication, request lifecycle, and versioning.
 * Database & Storage: PostgreSQL and Redis experience: schema design, query optimization, caching strategies, and consistency tradeoffs.
 * Distributed Systems: Strong distributed systems intuition: consistency models, event-driven replication, and the implications of global state propagation.
 * High Agency: High standards for correctness and security; curious, self-directed, and comfortable driving ambiguous problems to resolution across team boundaries., * Experience with credential and token lifecycle systems: issuance, rotation, scoping, revocation, or service-to-service authentication at scale.
 * Familiarity with the Cloudflare developer platform: Workers, Durable Objects, KV, R2, etc.
 * Experience incrementally re-architecting a large, long-lived codebase under production traffic, and familiarity with containerized deployment (Docker, Kubernetes), infrastructure as code (Terraform), and observability tooling (Prometheus, Grafana, Kibana).

## Description

* Feature development: design and build high-throughput, low-latency IAM capabilities that power both customer-facing and internal service APIs.
 * System evolution: contribute to the design and evolution of our authentication and authorization systems into modern, distributed, and edge-capable architectures.
 * API and system design: translate product and security requirements into robust, well-structured APIs and technical specifications in collaboration with Product, Security, and UX teams.
 * Engineering excellence: maintain a high bar through thorough code reviews, technical design documents, and collaborative problem-solving.
 * Operational stewardship: own the reliability of the platform under constant load, ensuring observability and resilience are built into every service.
 * AI-assisted development: use AI tools throughout your workflow, from code generation to debugging, and bring the judgment to know when to trust them.
