You will build a fluid, intuitive, and polished user experience from the ground up. * Designer-in-Lockstep Collaboration: Work "hand-in-glove" with our dedicated UX/UI designer, engaging in rapid daily iteration to translate high-fidelity, interactive prototypes into pixel-perfect, production-ready code. * Real-Time Data Streaming: Engineer the high-performance "live transcript" view, which displays the AI-screened conversation as the phone is ringing. This involves consuming real-time streaming text data from our backend AI orchestration layer via WebSockets. * Mastering Perceived Performance: Implement the critical "mid-call intervention" feature, allowing a user to seamlessly accept a call from the AI agent. You will become an expert in designing for our < 1000ms V2V (voice-to-voice) latency budget, ensuring the entire UX flow feels fast and responsive. * API & Backend Integration: Partner with our backend (Application & AI Orchestration) engineers to define and integrate the client-side APIs and data models required to power the Welcome Manager's features, from live transcription to post-call entity-extracted summaries. * MWC Demo Ownership: Be directly responsible for the polish, stability, and performance of the Welcome Manager application for its critical debut at MWC 2026. * Cross-Functional Partnership: Collaborate closely with the other Senior Android Engineer (who owns the native CallScreeningService and Security Shield overlay) to ensure a seamless and unified user experience between our two core products within a single application. ## Related Videos - [Kotlin Multiplatform - True power of native code reuse](https://www.wearedevelopers.com/videos/4-kotlin-multiplatform-true-power-of-native-code-reuse) - [For the Cars and the Curious: Android Drift](https://www.wearedevelopers.com/videos/499-for-the-cars-and-the-curious-android-drift) - [Web APIs you might not know about](https://www.wearedevelopers.com/videos/281-web-apis-you-might-not-know-about) - [Boost Productivity with AI: Figma & Playwright MCP Workflows - Aris Markogiannakis](https://www.wearedevelopers.com/videos/1768-boost-productivity-with-ai-figma-playwright-mcp-workflows-aris-markogiannakis) - [Android beyond mobile: Cars, TVs, and Wearables](https://www.wearedevelopers.com/videos/553-android-beyond-mobile-cars-tvs-and-wearables) - [Project Fugu: Extending the web](https://www.wearedevelopers.com/videos/832-project-fugu-extending-the-web) ## Related Articles - [Cross Platform Mobile Development Frameworks to Use in 2025](https://www.wearedevelopers.com/magazine/404-cross-platform-mobile-development-frameworks-to-use-in-2025) - [Basic And Advanced Networking in Dart and Flutter](https://www.wearedevelopers.com/magazine/112-basic-and-advanced-networking-in-dart-and-flutter) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [A Guide to Choosing the Right Tools for App Developers](https://www.wearedevelopers.com/magazine/391-a-guide-to-choosing-the-right-tools-for-app-developers)
