Software Engineer, Enterprise Platform at Cursor (San Francisco, CA)Software Engineer, Enterprise Platform

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.

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.

• 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

Experience designing and building scalable systems or shared platform infrastructure.

• Opinions on permission models, role inheritance, and policy evaluation
• Experience building multi-tenant organization or IAM systems in production and opinions on permission models, role inheritance, and policy evaluation
• Experience shipping RBAC or ABAC systems and understand the tradeoffs between flexibility and complexity
• Care deeply about correctness in authorization and understand why "fail closed" matters
• Able to hold the tension between "ship enterprise features fast" and "do not create security gaps or break existing access patterns."
• Feel comfortable shipping features end-to-end, from database schema and API design to admin UI and documentation

• Onsite role: must be able to work in person at the San Francisco office
