• Obsess over the reliability and performance of what you build, profiling and testing across edge cases
• Diagnose problems across application, runtime, native platform, and operating system boundaries

Qualifications

• 3+ years experience building application frontends, ideally for an Electron or native desktop product
• Deep expertise in TypeScript and React, or Swift and Objective-C
• Know how to profile application performance and trace problems through the software stack
• Understand the operating system beneath the application, including processes, threads, memory, filesystems, networking, and platform APIs
• Love the craft of high-end UI
• Think and build in terms of the overall user workflow while still sweating the small stuff
• Thrive in a fast-paced, shipping-oriented environment
