Senior Fullstack Engineer (RoR/vue.js), Software Supply Chain Security: Authorization
An overview of this role
As a Senior Full Stack Engineer on the Authorization team at GitLab, you'll build the critical systems that determine who can access what across the entire GitLab platform—impacting millions of users from startups to Fortune 500 enterprises. This role focuses on architecting and implementing GitLab's next-generation Authorization infrastructure, including policy-as-code systems, fine-grained permissions, and performance optimization at massive scale..
Your contributions will directly enable GitLab's evolution toward zero-trust architecture while ensuring authorization decisions remain fast, secure, and correct.
This is a unique opportunity to solve authorization challenges at global scale while working with cutting-edge authorization frameworks and modern policy languages.
What You'll Do
Implement fine-grained permission systems for Job Tokens, Personal Access Tokens, Duo agent platform and other authentication mechanisms
Collaborate with Security, Database, and Platform teams on the new Auth stack initiative
Solve complex performance challenges including authorization query optimization, caching strategies, and database decomposition
Design authorization systems that work seamlessly across multiple deployment models and multi-tenant architectures
Advocate for improvements to authorization security, maintainability, and developer experience through code review and technical leadership
Contribute to architectural decisions for authorization features with a 12-month+ strategic view
Mentor team members on authorization patterns, policy languages, and secure coding practices
What You'll Bring
Significant professional experience with Ruby on Rails and Vue.js in production environments
Strong understanding of authorization concepts: RBAC (Role-Based Access Control), ABAC (Attribute-Based Access Control), and fine-grained access control patterns
Experience with high-scale backend systems that handle millions of requests per day
Deep knowledge of database optimization, particularly PostgreSQL performance tuning and query optimization
Familiarity with policy-based authorization systems or strong interest in learning Cedar, Rego, or similar policy languages
Understanding of security principles including threat modeling, least-privilege access, and zero-trust architectures
Experience with distributed systems, caching strategies, and service-to-service communication
Proven ability to own complex technical initiatives from design through production deployment
Strong collaboration skills for working across multiple engineering teams in an asynchronous, remote environment
Comfort working in a highly agile, iterative development process with focus on shipping value incrementally
About the team
The Authorization team is responsible for building and maintaining GitLab's permission systems to be more secure, scalable, and flexible. We're currently executing a major authorization systems redesign that will fundamentally transform how authorization works across GitLab.
The team works closely with:
Authentication & Product Security teams for integrated identity and access management
Database team for query optimization and data model design
Security team for threat modeling and security architecture reviews
