Software Engineer, Client Infrastructure
Designs and builds performant, stable client infrastructure for Cursor's desktop app across macOS, Windows, and Linux. Requires deep experience in client systems, performance, reliability, and high-performance desktop applications.
About the job
Example projects include:
- Building core client infrastructure: shared abstractions, build systems, and observability foundations.
- Improving reliability and performance: eliminating memory leaks, crashes, and frame-time inconsistencies.
- Designing instrumentation and telemetry systems for profiling, structured logging, and performance measurement.
- Partnering with product teams to unlock faster release velocity—shipping updates to users daily.
- Evaluating Electron vs. native approaches for critical code paths, guiding architectural tradeoffs.
- Building internal tooling that enables other engineers to ship safely and quickly on the client platform.
You might be a fit if:
- You have deep experience in client infrastructure—build systems, performance, distribution, or observability.
- You’ve built or contributed to high-performance desktop applications, whether Electron-based or native.
- You care deeply about performance, reliability, and developer experience, and have an eye for elegant systems design.
- You thrive in environments that are fast-moving, collaborative, and product-focused.
- You’re excited to push the limits of what’s possible in AI-driven developer tools.
