• Optimize performance across JS thread, UI thread, and native layers
• Identify and fix bottlenecks in rendering, memory, and startup time
• Own CI/CD pipelines and App Store / Play Store release processes end-to-end
• Collaborate with backend, design, and product in a fast-paced environment
• Mentor mid-level engineers and contribute to technical decisions

What We’re Looking For

• 4+ years of mobile development experience
• Deep understanding of React Native internals (bridge, threads, rendering)
• Solid fundamentals in concurrency, parallelism, and threading
• Experience writing native modules and platform-specific integrations
• Proven ownership of CI/CD pipelines (Fastlane, GitHub Actions, Bitrise, etc.)
• Experience profiling and optimizing render performance, memory, and startup time
• Ability to explain trade-offs and make pragmatic engineering decisions
