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, including agent-assisted vulnerability discovery across our codebase.
  • Research the security posture of open source tools and dependencies integrated with GitLab, report findings to their maintainers, and track mitigation following responsible disclosure guidelines.
  • Solve technical problems of the highest scope, complexity, and ambiguity.
  • Help shape the team and sub-department roadmap.
  • Lead the integration of security research results into the engineering and business functions that need to act on them.
  • Teach, mentor, and advise other domain experts and individual contributors across several teams.
  • Share knowledge and novel vulnerability types with the security community.

What we're looking for

  • 10+ years of experience in security research, penetration testing, or offensive security roles
  • Strong ability in discovering and exploiting vulnerabilities in large codebase and complex systems
  • Proficiency in two or more of Ruby, Go, Python, TypeScript, or Rust.
  • Ability to read and analyze code across multiple languages and codebases
  • Strong knowledge of AI frameworks
  • Strong understanding of AI attack vectors including prompt injection, agent manipulation, and workflow exploitation
  • At ease in establishing and driving complex remediation initiatives involving cross-functional teams
  • Excellent written communication skills with an ability to articulate complex topics in a clear and concise manner.
  • Ability to translate complex technical findings into clear risk assessments and remediation recommendations
  • Strong analytical and problem-solving skills with creative thinking about attack scenarios

Nice to have

  • Published security research or conference presentations
  • Background in software engineering with distributed systems expertise
  • Experience with GitLab or similar DevSecOps platforms
