Software Engineer, Client Infrastructure

As an Engineer on the Client Infrastructure team at Cursor, you’ll design and build the systems that make our desktop experience performant and stable for millions of developers.

You’ll work across the core architecture of the Cursor client—from build and distribution systems to performance instrumentation and shared abstractions that other teams rely on. The work is deeply technical and central to the company’s success. Developers expect near-perfect performance and reliability from their trusted tools; your work will make that possible.

Cursor’s client is growing fast, spanning macOS, Windows, and Linux, and serving an increasingly diverse user base of professional engineers across many programming languages and developer ecosystems. You’ll shape the systems that let us ship safely and quickly, while pushing the limits of what’s possible in an AI-driven development environment.

Building core client infrastructure: shared abstractions, build systems, and observability foundations.
