About the Role A1 is building a proactive AI chat app for everyday users to bring intelligence to conversations, errands, organising and workflows. Unlike traditional chat-based applications, 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. You will own how this system behaves on desktop environments. Your work focuses on reliability, performance, and real-time behavior in production desktop applications. Focus Build and maintain cross-platform desktop applications using Electron. Design responsive and scalable UIs for real-time collaboration. Implement desktop-specific functionality including file system access, native notifications, auto-updates, and deep linking. Integrate AI-powered features (chat, agents, AI assistance) via backend APIs. Optimize startup time, memory usage, and runtime performance. Profile and reduce Electron overhead. Manage large local state and message history efficiently. Ensure smooth real-time updates (messages, typing indicators, presence). Maintain stability across macOS and Windows environments. Ideal Experiences Proven software engineering experience. Hands-on experience building production Electron applications. Strong proficiency in JavaScript and TypeScript. Experience with React or similar UI frameworks. Solid understanding of the desktop application lifecycle. Experience with IPC communication. Experience working with local storage (SQLite, IndexedDB, filesystem). Experience with WebSockets or other real-time transport mechanisms. Strong debugging and performance profiling skills. Familiarity with native OS behaviors on macOS or Windows.
