Senior React Native Engineer

Build cross-platform apps in React Native and TypeScript that feel native on both iPhone and Android, and dive into Swift or Kotlin when the job needs it.

What you'll do

• Design, build and ship features in React Native and TypeScript for iOS and Android.
• Write and maintain native modules in Swift and Kotlin, including in-app purchases on both stores.
• Ship releases to the App Store and Google Play, and keep both builds healthy.
• Profile and fix performance problems: startup time, lists, animations and memory.
• Review code, mentor other engineers and help decide when to go cross-platform and when to go native.
• Work with our ASO and ads specialist on onboarding, paywalls and experiments.

What you bring

• 5+ years building mobile apps professionally, including 3+ years of React Native in production.
• Strong TypeScript and React, and a good understanding of React Native's new architecture.
• Enough Swift and Kotlin to write a native module and debug a native crash.
• Experience releasing on both the App Store and Google Play.
• Clear written communication: you explain your choices and write things down.

Nice to have

• Expo, EAS and over-the-air updates.
• Localizing apps in English and French.
• Education or exam-preparation apps.
