Title: Zanzibar-Inspired Authorization System for A79 Products

Description: Design and implement a fine-grained access control system for A79's product suite, inspired by Google's Zanzibar authorization model. The system will manage permissions across various metadata entities, support user groups and flexible sharing capabilities, and integrate seamlessly with existing A79 products. This authorization layer should be performant, scalable, and provide a consistent permission model across the entire product ecosystem.

Required Skills & Traits:

Strong background in backend development and distributed systems

Understanding of authorization concepts and security principles

Experience designing and implementing complex permission systems

Knowledge of graph-based data structures and their manipulation

Familiarity with high-performance caching strategies

Ability to design clean, intuitive APIs for internal consumption

Attention to detail and commitment to security best practices

Expected Outcomes:

A centralized authorization service implementing Zanzibar concepts

APIs for permission checking, relationship management, and authorization administration

Integration with existing A79 products and identity management systems

Comprehensive test suite ensuring correctness of authorization decisions

Performance benchmarks demonstrating capability to handle expected load

Documentation covering architecture, API usage, and extension patterns

Specific courses required for project execution:
