Senior Flutter Engineer (3–5 Years) – E-commerce App Development

Overview

We’re looking for a Senior Flutter Engineer (3–5 years experience) who can own the end-to-end mobile engineering lifecycle for a high-scale e-commerce application. This role requires strong Flutter expertise, solid mobile architecture knowledge, performance mindset, analytics/CRM maturity, and the ability to ship production-grade apps reliably. Native iOS/Android experience is a plus.

Core Responsibilities

1) Flutter Development & Architecture

• Design and develop Flutter-based e-commerce apps using clean architecture, modular codebase, and scalable folder structure.
  
  

• Own and implement critical e-commerce flows:
  
  

  • Product listing (PLP), PDP, cart, checkout
    
    

  • Login/authentication, search & filters
    
    

  • Payments, offers/coupons, order tracking
    
    

  • Push notifications & deep links
    
    

• Drive consistency in coding standards, dependency management, modularization, and code reuse.
  
  

2) Performance & Quality Ownership

• Optimize app startup time, memory usage, smoothness (jank), frame drops, and rendering performance.
  
  

• Build and enforce production-grade error handling, crash prevention, and observability.
  
  

• Ensure high stability in real-world conditions:
  
  

  • Slow network, offline mode, high latency, device constraints
    
    

• Own debugging using Flutter DevTools, Crashlytics, logging and profiling tools.
  
  

3) Integrations: Backend + SDK Ecosystem

• Integrate backend services via REST / GraphQL, ensuring efficient network handling, retries, caching, and token refresh.
  
  

• Implement and maintain integrations with 3rd party services commonly used in e-commerce:
  
  

  • Payments, OTP/login SDKs, delivery tracking, fraud/security tools
    
    

• Collaborate with backend teams for API contracts, latency improvements, and release coordination.
  
  

4) Analytics & CRM Engineering

• Own analytics implementation with GA4 / Amplitude / PostHog:
  
  

  • Event taxonomy, naming conventions, properties, tracking plan
    
    

  • Funnel events across acquisition → conversion → retention
    
    

• Integrate CRM engagement platforms such as:
  
  

  • MoEngage / CleverTap / Braze
    
    

• Ensure:
  
  

  • Correct user identity mapping, segmentation events, push/in-app triggers
    
    

  • Deep links + campaign attribution correctness
    
    

5) CI/CD + Store Release Ownership

• Own App Store + Play Store release pipelines:
  
  

  • Build flavors, environments, signing keys, versioning strategy
    
    

• Manage release workflows using Fastlane / Codemagic / GitHub Actions
  
  

• Handle store-level operational responsibilities:
  
  

  • Rejections, rollout strategies, hotfix releases, store compliance
    
    

6) Engineering Leadership

• Mentor junior developers with best practices and hands-on reviews.
  
  

• Own PR quality, enforce branching strategy and review rigor.
  
  

• Contribute to improving engineering process:
  
  

  • Testing discipline, modularity roadmap, tech debt cleanup
    
    

Required Skills

• 3–5 years experience in Flutter/Dart with production apps shipped.
  
  

• Strong knowledge of state management patterns:
  
  

  • Bloc / Riverpod / Provider / MobX / GetX
    
    

• Strong fundamentals in:
  
  

  • App navigation, lifecycle, dependency injection, async programming
    
    

• Experience with:
  
  

  • Auth/session management, refresh tokens, secure storage
    
    

  • Caching, offline-first behavior
    
    

• Strong debugging/profiling experience:
  
  

  • Crashlytics, performance monitoring, log analysis
    
    

• Hands-on experience with:
  
  

  • Analytics and CRM implementation at granular event level
    
    

• Solid knowledge of:
  
  

  • Git/GitHub workflows, branching strategies, CI/CD pipelines
    
    

Good to Have

• Native experience: Swift / Kotlin / Java, platform channels, native modules
  
  

• Deep linking experience:
  
  

  • Universal links, dynamic links, attribution linking
    
    

• Payment integrations:
  
  

  • Razorpay / Stripe / Paytm / Cashfree
    
    

• Experience with:
  
  

  • Feature flags, Remote Config, A/B testing
    
    

  • CDN/image optimization, caching strategies
    
    

Key Traits

• Product mindset + engineering maturity (not just “feature delivery”).
  
  

• Strong ownership: can take a feature from spec → dev → QA → release → monitoring.

• High execution speed without compromising code quality.
  
  

• Proactive and reliable in production incidents and release cycles.
