  • Own ambiguous 0-to-1 projects across product pods, platform security controls, customer deployment workflows, and cyber model infrastructure.
  • Translate security research and model capabilities into intuitive workflows that help teams find, validate, prioritize, and remediate vulnerabilities with high signal.
  • Design scalable, observable systems for long-running analyses across large codebases and enterprise environments.
  • Partner with product, security research, infrastructure, and customer-facing teams to iterate quickly from real-world feedback.
  • Help shape the technical direction and architecture of Codex Cyber as the team and product surface area grow.

  • Security curiosity and ability to work across product, backend, infrastructure, and developer tooling
  • Experience building developer tools, workflow-heavy platforms, or security products for technical users
