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.
- Deepen our audit logging infrastructure — comprehensive, queryable, tamper-evident audit trails that satisfy customer-specific compliance requirements.
- Build admin APIs and internal tooling that enterprise admins, customer success, and sales engineering depend on to manage organizations, investigate access issues, and onboard large accounts.
- Ship compliance features end-to-end — SSO enforcement, session management, allowlisting, data analytics, and the controls that procurement and security teams require before signing.
- Partner with product, security, and infrastructure teams to define enterprise platform abstractions that scale across the product without slowing down feature development.
- You will own organization management, RBAC and authorization, enterprise settings and policies, audit logs, admin APIs, and compliance-related platform features. You will be a technical authority on how Cursor models identity, access, and governance for enterprise customers.
- You will not own SSO/IdP integration at the protocol level (we use WorkOS) or billing and payments.
- Security and correctness are part of the job, but the goal is to build systems with enough rigor and observability that enterprise operations are boring — not to manually triage every access control edge case.
You may be a fit if
- You've built multi-tenant organization or IAM systems in production and have opinions on permission models, role inheritance, and policy evaluation.
- You've shipped RBAC or ABAC systems and understand the tradeoffs between flexibility and complexity.
- You deeply about correctness in authorization and understand why "fail closed" matters.
- You can hold the tension between "ship enterprise features fast" and "do not create security gaps or break existing access patterns."
- You feel comfortable shipping features end-to-end — from database schema and API design to admin UI and documentation.
