An overview of the role We are seeking a Principal Security Researcher to join our Application Security Team to conduct cutting-edge security research on GitLab's AI-powered DevSecOps capabilities. As GitLab transforms software development through intelligent collaboration between developers and specialized AI agents, we need security researchers who can proactively identify and validate vulnerabilities before they impact our platform or customers. In this role, you'll be at the forefront of security research, working with our GitLab DevSecOps platform, Duo Agent Platform, GitLab Duo Chat, and AI workflows that represent the future of human/AI collaborative development. You'll develop novel testing methodologies (including for AI agent security), conduct hands-on penetration testing, and translate emerging threats into actionable security improvements. Your research will directly influence how we build and secure the next generation of AI-powered DevSecOps tools, ensuring GitLab remains the most secure software factory platform on the market. This position offers the unique opportunity to shape security and AI security practices in one of the world's largest DevSecOps platforms, working with engineering teams who are pushing the boundaries of what's possible with AI-assisted software development. You'll have access to cutting-edge AI systems and the freedom to explore creative attack scenarios while contributing to the security of millions of developers worldwide. This role reports to the Senior Manager of Application Security. What you'll do • Conduct and lead security research projects across multiple functional areas. • Identify novel, systemic, and chained vulnerabilities in GitLab, where individual weaknesses combine for outsized impact. • Validate security vulnerabilities through hands-on testing, developing proof-of-concept exploits that demonstrate real-world attack scenarios. • Assess emerging industry vulnerability classes against the GitLab codebase, and drive remediation of the class rather than the instance. • Lead security research into GitLab's AI and agentic surfaces, and define the security requirements that engineering teams build against. • Build and direct the tooling and automation that scales security research, includi
