An overview of this role

As a Senior Full Stack Engineer on the Authorization team at GitLab you’ll build and evolve the core systems that decide who can access what across the entire GitLab platform directly impacting millions of users from startups to large enterprises. You’ll architect and implement our next-generation authorization infrastructure including policy-as-code approaches fine-grained permissions and performance optimizations at massive scale enabling GitLab’s move toward zero-trust architecture while keeping authorization fast secure and correct. You’ll work closely with Security Database Platform and authentication-focused teams to design and ship authorization capabilities that span GitLab’s various deployment models and multi-tenant environments.

Some examples of our projects:

• Implementing fine-grained permissions for Job Tokens Personal Access Tokens and the GitLab Duo agent platform

• Collaborating on Auth stack initiatives that evolve how authorization works across GitLab

What you’ll do

• Implement fine-grained permission systems for Job Tokens Personal Access Tokens the GitLab Duo Agent Platform and other authentication mechanisms across the GitLab platform.

• Collaborate with Security Authentication Database and Platform teams on authorization stack initiatives aligning designs and implementation plans.

• Solve complex performance challenges in authorization including query optimization caching strategies and database decomposition with a focus on PostgreSQL.

• Design and evolve authorization systems that work across multiple deployment models and multi-tenant architectures while maintaining security and reliability.
