SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today, SpaceX is actively developing the technologies to make this possible, with the ultimate goal of making life multiplanetary and expanding consciousness to the stars.

SpaceXSI is building Super Intelligence to help humanity understand the universe. Our teams are building the full Super Intelligence stack: from our Colossus supercomputers, to Grok models, to our suite of applications, including Grok Bot, Grok Build, Grok Imagine, Grok Voice, and X. We're creating a powerful flywheel where more compute trains better models, better models power more useful products, and what we learn from people using those products shapes what we build next.

About the role

Cursor’s agents work inside the codebases of some of the most security-conscious engineering organizations in the world — holding credentials, reading untrusted content, running tools, and shipping changes. Today they act on authority delegated per task. Where we’re headed, they’ll work more like coworkers: autonomous over long horizons, holding standing responsibilities, initiating work, and collaborating with people and other agents. The security models that future needs — identity and accountability for autonomous workers, standing authority rather than per-task permission, agent-to-agent trust, oversight that scales with always-on autonomy — mostly don’t exist yet.

As Engineering Manager for Agent & Product Security, you’ll lead the team that makes agentic software development trustworthy. This team owns the security boundaries between customers, data, tools, repositories, workspaces, and agent authority across Cursor’s product and agents and designs the primitives behind them: agent identity, delegated authority, policy enforcement, secure tool execution, and prompt-injection containment. Little of this has settled precedent, so the team’s decisions carry unusual weight for Cursor and for how the industry approaches these problems.

Security here is tightly coupled to product strategy: customers adopt agent autonomy as fast as we can make it trustworthy, so the boundaries your team makes safe directly determine what the product can ship. You’ll help set that direction.

What you’ll do

• 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.
