Android Software Engineer

ABOUT A1 There are over 5 billion users using basic applications today such email, notes, tasks that are not AI-native. Our mission is to build a proactive smart assistant for everyday users to bring intelligence to conversations, errands, organising and workflows, with minimal prompting. Our product focuses on achieving high reliability for long-running workflows, persistent context, and real-world task completion. The system must handle multi-step reasoning, interact with external tools, and remain reliable despite non-deterministic model behavior. Our objective is to help users complete tasks daily enjoyable with over ~90%* reduced time. ROLE As an Android Software Engineer, you own the Android client experience, how AI feels, behaves, and performs on mobile devices. This is not a thin client role. You will build a production Android application where AI interactions are core to the product, and performance, reliability, and clarity matter. FOCUS - Build and maintain production Android apps using Kotlin. - Integrate AI-powered features (chat, vision, voice, recommendations) via backend APIs. - Design UX patterns for AI interactions, including streaming responses, retries, and partial results. - Optimize performance, memory usage, and responsiveness for AI-heavy flows. - Implement analytics, logging, and feedback capture to support AI evaluation and iteration. - Collaborate closely with backend and ML engineers on API contracts and system behavior. - Ensure app stability, security, and scalability in production environments. IDEAL EXPERIENCES - 3+ years of Android development experience using Kotlin. - Hands-on experience integrating AI features (e.g. LLM, vision, speech APIs). - Strong understanding of asynchronous programming (Coroutines, Flow). - Familiarity with REST or gRPC APIs and structured data formats. - Strong debugging and performance profiling skills. - Comfort building in environments with latency, partial failure, and non-deterministic behavior. - E
