• Integrate native components with Node/Electron using appropriate interfaces (e.g., Node-API/N-API, IPC) while maintaining security boundaries
• Improve application performance, reliability, and startup time through profiling, debugging, and optimization across JavaScript/TypeScript and C++ layers
• Manage core development infrastructure including framework upgrades, build processes, packaging, and release readiness
• Debug and resolve complex cross-platform issues in a multi-language codebase (Windows/macOS/Linux)
• Maintain code quality through automated testing, code reviews, and clear documentation
• Drive continuous improvements in architecture, processes, and tooling

Requirements:

• 5+ years of professional software engineering experience delivering production applications
• 5+ years of C++ experience in a native development context, including memory management, performance tuning, and debugging
• 3+ years of experience building production UIs with React (JavaScript/TypeScript)
• 3+ years of experience with Node.js and JavaScript/TypeScript development; Electron experience strongly preferred
• Experience integrating C++ components with JavaScript runtimes (e.g., native Node modules via Node-API/N-API or comparable approaches)
• Experience debugging cross-platform applications and working effectively in multi-language codebases
• Familiarity with modern front-end fundamentals (HTML, CSS) and UI engineering best practices
• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience
• Experience shipping Electron applications at scale, including packaging/signing and release processes across Windows/macOS
• Experience with Electron security best practices (context isolation, sandboxing, secure IPC patterns)
• Experience profiling and optimizing desktop apps (startup time, memory usage, CPU utilization)
• Familiarity with automated testing for desktop apps (unit/integration/e2e) and CI/CD pipelines
• Experience working on security products or security-sensitive applications
