About The ClientOur 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 OverviewWe 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 OrchestrationArchitect and maintain a scalable Flutter codebase capable of hosting multiple "mini-apps" (Fintech, Lifestyle, Identity) within a single ecosystemImplement complex user lifecycles, including SSO (Single Sign-On), multi-factor authentication and tiered KYC (Know Your Customer) workflowsLead the integration of multi-provider Payment Systems (Apple/Google Pay, Stripe and direct banking APIs) Agentic & Conversational InterfacesDesign 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 interactionsIntegrate mobile-side AI agents that can perform actions on behalf of the user across different modules of the Super App Fullstack EngineeringDevelop and optimise high-concurrency Backend APIs (Python/Node.js/Go) that power the mobile experienceDesign secure data synchronisation patterns for offline-first capabilities and real-time state managementManage infrastructure for mobile-specific needs, such as push notification orchestration and OTA (Over-The-Air) updates Performance & SecurityEnsure the Super App maintains a 60fps+ performance profile even with heavy AI and media processingImplement rigorous security standards for handling sensitive financial and identity data (biometrics, secure enclave, encrypted storage)RequirementsTechnical RequirementsMobile Framework: Flutter (Expert), Dart, Platform Channels (Swift/Kotlin)AI Integration: TTS/STT (Whisper, ElevenLabs, Google Cloud Speech), OpenAI/Claude SDKsSuper App Features: SSO (OAuth2, OpenID Connect), KYC (Sumsub, Jumio), Payments (Stripe, Adyen)Backend: Python (FastAPI/Django) or Node.js, REST/GraphQL, WebSocketsState Management: Riverpod, Bloc or SignalsDevOps / Mobile Ops: CI/CD (GitHub Actions, Fastlane), App Store/Play Store automationSecurity: JWT, OAuth2, Biometric Auth, ProGuard/R8, SSL PinningMandatory Keywords: Flutter, Dart, Super App, Backend APIs, TTS/STT, SSO, KYC, PaymentsPeripheral 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 NotificationsThe "Modern Take": What We ExpectBeyond the Grid: You don't just build lists and buttons. You think about how an AI agent can "drive" the UI for the userVoice-Native: You understand the nuances of voice UX: handling interruptions, background noise and emotional prosody in TTSSecurity by Design: You treat KYC and Payment flows as mission-critical infrastructure, not just API callsProduct Mindset: You bridge the gap between "what is technically possible" and "what feels like magic for the user."Preferred QualificationsExperience 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 featuresStrong understanding of Micro-frontend or Micro-app architectures in a mobile contextWhy JoinWe are moving past the era of "apps as tools" into the era of "apps as partners."
