Engineering Manager, Agent & Product Security

Responsibilities

• Chart the path from supervised agents to trusted autonomous ones: define the security primitives that enable agent autonomy, and lead the team that builds them.
• Engineer the isolation that makes Cursor safe to run inside customers’ most valuable codebases: tenancy, workspace, secret, and data protections designed for real adversaries.
• Build the authority infrastructure autonomous agents need: identity, scoped permissions, policy enforcement, and secure tool execution, so an agent can hold real responsibility with verifiable limits and full accountability.
• Build customer-facing security controls that are understandable, usable, and strong enough for Cursor’s most security-sensitive customers, with crisp success metrics for security outcomes.
• Hire, coach, and grow a high-performing security engineering team while staying technically close to the work: write and review code where useful, and keep execution fast and technically grounded.

Requirements

• Led engineering teams shipping production systems with high security, reliability, or platform stakes.
• Strong product and systems judgment: reason from user workflows to architecture, threat models, enforcement points, and operational tradeoffs.
• See security as something that enables product capability, not only restricts it.
• Understand modern application security, authorization, tenancy, identity, secrets, data isolation, and secure-by-default platform design.
• Good instincts about AI agents: how they use tools, where authority should come from, how prompt injection and exfiltration show up in practice, and how to build mitigations that hold up against creative adversaries.
• Comfortable operating in ambiguity: set strategy where precedent is thin, commit to a direction, and stay close enough to the implementation to know when to change it.
• Partner well across product, infrastructure, ML, and customer-facing teams.

Nice-to-Haves

• Experience in a small, talent-dense, flat organization.
• Passion for truth-seeking, creative problem-solving in AI and security.
