As a Senior Full Stack Engineer on the Authorization team at Git Lab, you’ll build and evolve the core systems that decide who can access what across the entire Git Lab 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 Git Lab’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 Git Lab’s various deployment models and multi‑tenant environments.
