Job description

React Native TypeScript iOS Android Native Modules CI/CD App Store Release Performance

We are hiring a senior mobile engineer who can lead the mobile pillar of a delivery squad. You will own architecture, release pipelines, and on-device quality for apps that real users depend on every day.

• Mobile architecture. Design app architecture, navigation, offline strategy, and native bridges for production-grade React Native and / or native projects.
• Release engineering. Own CI/CD, signing, beta channels, App Store and Play Store releases, and crash triage.
• Quality. Own performance budgets, memory profiles, accessibility, and device-coverage strategy.
• Cross-platform decisions. Make pragmatic calls between React Native, native modules, and platform SDKs based on the product.
• 5+ years of mobile engineering with shipped apps in stores (React Native, Swift, or Kotlin).
• Deep TypeScript experience and comfort writing native modules when needed.
• Strong sense of when to reach for native and when to stay cross-platform.
• Experience with offline-first sync, push notifications, deep links, and OAuth flows.
• Track record of release ownership: signing, provisioning, store reviews, and rollout strategies.
• Experience with Expo / EAS, Fastlane, or custom CI for mobile.
• Background in Bluetooth, camera, audio, payments, or other on-device hardware.
• Performance work using Hermes, JSI, or platform profilers.

Mobile is treated as a first-class delivery surface, not a secondary port of a web app. You will pair with web, backend, and design engineers to keep flows consistent across surfaces while respecting the platform conventions of each store.
