Responsibilities

  • Design and ship authorization changes in GitLab’s Ruby on Rails monolith.
  • Own workstreams from problem definition through feature-flagged rollout, dual-run verification, and cleanup.
  • Build and extend fine-grained permissions for tokens and roles and maintain the permission catalog.
  • Extend and harden authorization enforcement across GraphQL and REST APIs.
  • Refactor policy code so it can be evaluated by both the monolith and the new authorization engine without changing existing behavior.
  • Improve the reliability, performance, and security posture of authorization systems.
  • Partner with authentication, platform, AI, and modular-service teams on shared authorization interfaces.
  • Drive technical decisions through design documents, architecture decision records, and code review in an asynchronous organization.

Requirements

  • Significant experience building and operating production Ruby on Rails applications.
  • Experience designing or implementing authorization systems, including role-based access control and fine-grained permissions.
  • A security mindset with the ability to assess the blast radius of permission bugs.
  • Comfort making careful incremental changes to large, long-lived codebases, including feature-flagged rollouts and behavior-preserving migrations.
  • Working knowledge of GraphQL and API authorization patterns.
  • Understanding of performance considerations at scale, including repeated permission checks per request.
  • Strong written communication for document- and merge-request-driven collaboration.
  • Helpful but not required: Rust, gRPC or Protocol Buffers, Cedar or other policy languages, Zanzibar-style authorization systems, Go, or service-oriented architecture.
  • Transferable experience from identity, policy engines, or platform security is welcome.

Benefits

  • Health, financial, and well-being benefits.
  • Flexible paid time off.
  • Team Member Resource Groups.
  • Equity compensation and Employee Stock Purchase Plan.
