Staff Engineer

Job Description :

Role & Responsibilities :

1. Multi-Platform Architecture :

- Shared Logic Strategy : Lead the strategy for sharing business logic (Auth, State Management, API layers) across platforms leveraging TypeScript for web and Dart for Flutter, or exploring Kotlin Multiplatform (KMP) for core logic.

- Hybrid Interop : Manage the complexities of WebViews and JS Bridges within hybrid environments, ensuring seamless data passing and authentication persistence between native and web layers.

2. High-Scale Performance (Mobile & Web) :

- Flutter Optimization : Optimize Flutter rendering for 60 FPS performance. Youll be responsible for identifying and fi xing "jank" using DevTools, optimizing heavy list views, and managing complex widget trees.

- Binary Size & Bundle Management : Maintain strict budgets for App Store/Play Store binary sizes and Web JS bundles to ensure high conversion in regions with varied network conditions.

- Over-the-Air (OTA) Strategy : Implement and manage OTA update systems (like Shorebird for Flutter or custom CodePush-style solutions) to bypass store delays for critical hotfixes.

3. Infrastructure & Reliability :

- Universal CI/CD : Architect a pipeline that handles Fastlane for mobile deployments and optimized Vercel/Docker builds for web, ensuring a unified release cadence for 200k DAU.

- Observability : Set up cross-platform monitoring using Sentry, New Relic, or Firebase Crashlytics to maintain a 99.9% crash-free session rate across all devices.

Preferred candidate profile :

- Deep Flutter Expertise : 4+ years of Flutter experience with a deep understanding of Provider, Riverpod, or BLoC patterns and the Dart FFI.

- Modern Web Mastery : Expert-level React 19+, Next.js, and TypeScript.

- The "Hybrid" Bridge : Proven experience shipping high-traffic apps that utilize Native Channels or specialized Platform-specific implementations.

- Scale Experience : You have previously managed a frontend ecosystem for a product with at least 1 Lakh+ DAU.

- Knowledge of how to optimize for low-end Android devices and older browser versions without compromising the experience for high-end users.

- You don't just write Flutter or React; you define how they talk to each other. You are the fi nal word on cross-platform technical debt.

- You will upskill Web engineers in Dart/Flutter and vice-versa, creating a truly "T-shaped" engineering culture.

- You stay ahead of the curve, evaluating the impact of Wasm, Server-Driven UI, and AI-generated layouts on our specific scale.
