Senior Mobile Systems Engineer (Flutter & Agentic AI)
The Greater Change
Role:About The Client
Our client is a Dubai-based real estate and hospitality developer creating technology-led, design-driven communities. They combine smart living systems, ambient AI and longevity-focused environments in every project. Digital innovation sits at the core of their customer experience and long-term vision. They are now building a next-generation mobile ecosystem to connect residents, services and intelligent agents.
Role Overview
We are looking for a Senior Mobile Systems Engineer who views mobile development not just as "building screens," but as architecting the primary interface for Agentic Intelligence. You will build a high-performance Super App that seamlessly integrates financial services, identity and ambient AI.
This is a hybrid role requiring deep Flutter expertise and strong Backend engineering skills. You will lead the transition from static, menu-driven interfaces to Agentic UIs that leverage Voice (TTS/STT), Vision and Generative UI patterns to anticipate and serve user needs.
Key Responsibilities
Super App Orchestration
Architect and maintain a scalable Flutter codebase capable of hosting multiple "mini-apps" (Fintech, Lifestyle, Identity) within a single ecosystem
Implement complex user lifecycles, including SSO (Single Sign-On), multi-factor authentication and tiered KYC (Know Your Customer) workflows
Lead the integration of multi-provider Payment Systems (Apple/Google Pay, Stripe and direct banking APIs)
Agentic & Conversational Interfaces
Design and build Agentic Interfaces where the UI dynamically adapts based on AI-inferred user intent (GenUI)
Implement low-latency, streaming TTS (Text-to-Speech) and STT (Speech-to-Text) systems for ambient and voice-first interactions
Integrate mobile-side AI agents that can perform actions on behalf of the user across different modules of the Super App
Fullstack Engineering
Develop and optimise high-concurrency Backend APIs (Python/Node.js/Go) that power the mobile experience
Design secure data synchronisation patterns for offline-first capabilities and real-time state management
Manage infrastructure for mobile-specific needs, such as push notification orchestration and OTA (Over-The-Air) updates
Performance & Security
Ensure the Super App maintains a 60fps+ performance profile even with heavy AI and media processing
Implement rigorous security standards for handling sensitive financial and identity data (biometrics, secure enclave, encrypted storage)
Requirements
Technical Requirements
Mobile Framework: Flutter (Expert), Dart, Platform Channels (Swift/Kotlin)
AI Integration: TTS/STT (Whisper, ElevenLabs, Google Cloud Speech), OpenAI/Claude SDKs
Super App Features: SSO (OAuth2, OpenID Connect), KYC (Sumsub, Jumio), Payments (Stripe, Adyen)
Backend: Python (FastAPI/Django) or Node.js, REST/GraphQL, WebSockets
State Management: Riverpod, Bloc or Signals
DevOps / Mobile Ops: CI/CD (GitHub Actions, Fastlane), App Store/Play Store automation
Security: JWT, OAuth2, Biometric Auth, ProGuard/R8, SSL Pinning
Mandatory Keywords: Flutter, Dart, Super App, Backend APIs, TTS/STT, SSO, KYC, Payments
Peripheral Keywords: Swift, Kotlin, Platform Channels, Whisper, ElevenLabs, Google Cloud Speech, OpenAI, Claude, OAuth2, OpenID Connect, Sumsub, Jumio, Stripe, Adyen, Apple Pay, Google Pay, Python, FastAPI, Django, Node.js, Go, REST, GraphQL, WebSockets, Riverpod, Bloc, Signals, CI/CD, GitHub Actions, Fastlane, JWT, Biometric Auth, SSL Pinning, ProGuard, TensorFlow Lite, CoreML, Micro-frontend, GenUI, Agentic UI, Offline-First, Push Notifications
The "Modern Take": What We Expect
Beyond the Grid: You don't just build lists and buttons. You think about how an AI agent can "drive" the UI for the user
Voice-Native: You understand the nuances of voice UX: handling interruptions, background noise and emotional prosody in TTS
Security by Design: You treat KYC and Payment flows as mission-critical infrastructure, not just API calls
Product Mindset: You bridge the gap between "what is technically possible" and "what feels like magic for the user."
Preferred Qualifications
Experience building apps with 1M+ MAU (Monthly Active Users)
Contributions to the Flutter ecosystem (open-source packages or plugins)
Experience with on-device ML (TensorFlow Lite, CoreML) for privacy-preserving AI features
Strong understanding of Micro-frontend or Micro-app architectures in a mobile context
Why Join
We are moving past the era of "apps as tools" into the era of "apps as partners." You will be the lead architect of this transition, building the most sophisticated mobile entry point for agentic systems in the market.
