Cursor is an AI-powered coding platform and IDE designed to make software developers extraordinarily productive. It combines AI-assisted autocompletion, agentic programming assistants, a CLI agent, and deep codebase indexing to help developers write, review, and refactor code faster. Cursor integrates with GitHub, Slack, and enterprise tooling, offers access to multiple large language models, and is positioned as a secure, enterprise-capable SaaS product used by professional teams.

📋 Description

• Design and build the systems that make our desktop experience performant and stable for millions of developers. • Work across the core architecture of the Cursor client—from build and distribution systems to performance instrumentation. • 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. • 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.

🎯 Requirements

• 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.
