Software Engineer, Enterprise Platform

About this role

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

We're hiring an Enterprise Platform Engineer to build the foundational systems that make Cursor ready for the world's largest engineering organizations.

Today we have basic organizations, simple IAM primitives, early audit logs, analytics APIs, and admin APIs — but enterprise customers need much more. You will design and build the platform layer that powers organization management, access control, compliance, and administrative tooling across Cursor's product surface. This is a deeply technical IC role focused on building correct, secure, and scalable enterprise infrastructure — not gluing together vendor SDKs.

What you’ll do

• Build and evolve our organization management system — multi-level org structures, groups, roles, lifecycle, and provisioning via SCIM, so admins can manage thousands of seats without friction.

• Design and implement RBAC with fine-grained roles, permissions, and resource scopes that cover organizations, teams, agents, and other resources — balancing security with developer ergonomics.

• Extend enterprise settings and policies — org-wide defaults, security policies (allowed models, MCPs, Tools, network restrictions), and configuration inheritance across different products.
