Job summary

Ando seeks a mobile engineer to own shipping features in our Expo/React Native app, from design through App Store submission. You will set performance targets, instrument the app to catch regressions, and occasionally add native Swift/Kotlin modules for platform-specific needs.

• Set and measure performance benchmarks (start time, scrolling, animation smoothness, bundle size) and instrument the app to catch regressions
• Drop into native code (Swift/Kotlin) for modules, SDKs, or platform-specific behavior
