Software Engineer, Client Infrastructure
Cursor, San Francisco, CA
The role
As an Engineer on the Client Infrastructure team at SpaceXSI, 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.
What you will do
- Build core client infrastructure: shared abstractions, build systems, and observability foundations
- Improve reliability and performance: eliminating memory leaks, crashes, and frame-time inconsistencies
- Design instrumentation and telemetry systems for profiling, structured logging, and performance measurement
- Partner with product teams to unlock faster release velocity, shipping updates to users daily
