Staff Engineer - Frontend & Mobile

The core responsibilities for the job include the following:

Multi-Platform Architecture:

• Unified Design System: Architect a design system (using Tools like Flutter-Web or Figma-to-Code pipelines) that ensures visual and functional consistency across Web, iOS, and Android.
• 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.

High-Scale Performance (Mobile and Web):

• Flutter Optimization: Optimize Flutter rendering for 60 FPS performance. You'll be responsible for identifying and fixing "jank" using DevTools, optimizing heavy list views, and managing complex widget trees.
• Binary Size and 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.

Infrastructure and 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.

Requirements:

• 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 final 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.
