Role Overview

We are looking for an experienced Flutter SDE III who can take complete ownership of architecture, performance optimization, and app scalability for our OTT mobile applications. This is a senior individual contributor role requiring deep technical expertise and the ability to influence design decisions at a product level.

Key Responsibilities

1. Architecture & Design (High-Impact IC Role)

• Own the end-to-end architecture of company’s Flutter mobile applications.
• Design scalable, modular, testable app ecosystems aligned with OTT-specific performance constraints.
• Lead decisions around state management, navigation hierarchy, API structure, offline capabilities, and security.

2. Performance & Device Optimization

• Diagnose and resolve mobile performance bottlenecks, including:
  • App startup time, FPS drops, memory leaks.
  • Heating issues, over-rendering, and expensive widget rebuilds.
  • Battery optimization, efficient network calls, caching strategy.
• Run in-depth profiling using tools like Dart DevTools, Android Profiler, and Xcode Instruments.

3. OTT-Specific Engineering

• Optimize video playback workflows for low-latency streaming.
• Implement efficient background processes for downloads, DRM, content sync, and push notifications.

4. Product & User Experience Ownership

• Collaborate closely with Product, Backend, and Video Engineering teams.
• Convert business/product requirements into high-performance technical solutions.
• Ensure UI/UX consistency across platforms while maintaining performance budgets.

5. Code Quality & Leadership

• Write clean, extensible, and maintainable code with strong adherence to SOLID and reactive programming principles.
• Review code for mid-level and junior engineers; act as a mentor across teams.
• Establish engineering standards, internal frameworks, and reusable components for long-term scalability.

Required Skills & Experience

Technical Must-Haves

• 6+ years of total experience with 3+ years in Flutter for large-scale products.
• Mandatory product-based company background (B2C scale preferred).

  • Bloc, Riverpod, Provider, or other state management approaches
  • Custom animations, rendering pipeline, shader-based optimization
  • Platform channels (Android/iOS) and native integrations
  • API integration, caching layers, offline-first architecture
• Strong understanding of mobile system design, scalable architecture, and low-level performance engineering.

Good to Have

• Experience with video streaming apps, OTT platforms, or media-heavy applications.
• Understanding of analytics frameworks (Firebase, Segment, Mixpanel).
• Exposure to CI/CD pipelines, automated testing, and fastlane.

Personality & Mindset

• Product thinking, not just feature-building.
• Ownership-driven with strong ability to take strategic technical decisions.
• Comfortable working in a fast-paced 0→1 and scale-up environment.

Why Join company?

• Work on a high-growth OTT app with millions of users.
• Opportunity to own the core mobile experience end-to-end.
