About the role

Notion is seeking an experienced engineer to define security foundations for AI products, building guardrails, automated tests, and production systems to enable safe shipping of features across agent runtimes, retrieval, content writes, and observability in a hybrid, in-office-focused environment.

Responsibilities

  • Define and build security architecture for product surfaces that operate across customer workspace content, including tool execution, content writes, retrieval, permission checks, provenance, and auditability.
  • Make the secure path the easy path for product teams by shipping reusable libraries, review patterns, test fixtures, and guardrails that prevent classes of vulnerabilities.
  • Build automated red-team and regression testing for risks such as prompt injection, indirect instruction following, data exfiltration, tool misuse, cross-tenant leakage, and unsafe workspace mutations.
  • Translate threat models for new product surfaces into concrete engineering requirements, production checks, and launch criteria.
  • Use production signals, incident learnings, and targeted experiments to harden Notion over time, then feed those learnings back into architecture and developer workflows.
  • Help define the security bar for how engineers use coding agents, MCP-enabled tools, hooks, and internal automation without introducing new risk.

Qualifications

  • 8-10+ years of experience designing, building, or securing complex software systems, and comfortable working in production code with product and platform engineers.
  • Security architecture judgment: ability to reason about permissions, data flow, and trust boundaries in complex systems and redesign them to be safer.
  • Security product strategy: ability to turn security risks into actionable product design or architecture.
