Engineering Manager, Core Services

You will lead the Core Services team at Cursor, 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. Cursor is redefining how developers write code, and your team is what makes that possible at scale. You'll build and operate the systems that every product team depends on, ensuring they are reliable, well-abstracted, and ready for whatever comes next.

You'll set technical direction for authentication, SCM integrations, webhook infrastructure, and end-to-end agent reliability, driving the quality of the services layer that the entire company builds on top of. You'll lead a small, high-impact team, write and review code, and partner closely with product and infrastructure teams to ensure Cursor's backend is rock-solid.

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.
