An overview of this role We are hiring a Staff Product Security Architect to join our Security Platforms and Architecture organization at GitLab. Rather than operating as a purely consultative body, Security Architecture at GitLab functions as a hands-on technical driver. Our mission is to embed proactive guidance directly into modern developer workflows and automated coding environments, embedding security standards into the software development process from the outset. We strive to enable teams to deliver secure, resilient software seamlessly while minimizing reliance on manual security gates. In this role, you will collaborate closely with product engineering organizations, spearhead architectural strategy for critical capabilities, and serve as the primary Security Owner driving risk reduction for key entries within our risk management framework.
