The opportunity
You will lead the Core Services team at SpaceXAI, owning the critical shared services that sit between our product surfaces and the infrastructure layer: auth, webhooks, and the backend systems that power agent workflows. SpaceXAI is redefining how developers write code, and…
What you'll do
Owning authentication: designing and implementing a scalable auth architecture that secures one of the most widely-used developer tools in the world.
Powering the agent backend: owning the infrastructure behind Cursor's agent workflows, optimizing for end-to-end performance and reliability as agents become central to the developer experience.
Building a robust webhook server: handling high-throughput event delivery with proper retry semantics, dead-letter queues, and observability so external integrations just work.
Hardening SCM integrations: building resilient abstractions over source control providers so Cursor stays rock-solid regardless of third-party conditions.
Driving end-to-end agent reliability: partnering with the client and inference teams to improve the full path from user action to agent response.
Hiring and growing the team: sourcing, interviewing, and closing top backend and services talent, while developing your engineers through coaching, mentorship, and high-leverage project assignments.
