What You'll Own - Build major web experiences across Chat, Notes, Calendar, Docs, and Sheets. - Develop complex interactions including real-time messaging, collaborative editing, rich-text editing, scheduling, tables, and spreadsheets. - Build reusable frontend architecture and components that work consistently across ActAI applications. - Integrate streaming AI responses, proactive actions, and model-driven experiences directly into product workflows. - Own frontend performance, responsiveness, reliability and accessibility across browsers and devices. - Work closely with product and design to take ideas from prototype to production quickly. What We're Looking For - Strong experience building complex, production web applications using React, TypeScript and modern frontend technologies. - Deep understanding of frontend architecture, state management, browser APIs, and performance. - Experience building highly interactive products such as chat, collaboration, productivity, document editing, calendars, or workspaces. - Experience with real-time systems, WebSockets, streaming APIs, or collaborative interfaces. - Strong product and UI judgment with attention to interaction details. - Able to independently own features from technical design through production. Outcomes - Users can communicate, write, organize and collaborate seamlessly across Chat, Notes, Calendar, Docs and Sheets. - Complex interactions such as group messaging, editing, scheduling and collaboration feel fast and reliable. - AI capabilities are integrated naturally into product workflows rather than added as separate chatbot experiences. - Frontend architecture remains fast, maintainable and reusable as ActAI expands into new applications and workflows.
