ChronoAI
is an advanced AI technology company specializing in human-centric artificial intelligence solutions. We combine cutting-edge natural language processing with personalized analysis frameworks to create AI systems that understand individual psychology, decision-making patterns, and personal context, delivering meaningful insights for personal and professional development.
The Role We are looking for a
Senior Frontend Engineer with hands-on experience building AI-powered interfaces , particularly chatbots, agent-driven workflows, and streaming LLM experiences. This role is frontend-heavy. You will own the design and implementation of UI components for a
multi-agent AI platform , including conversational interfaces, agent state visualization, and real-time interaction patterns. You will work closely with backend and AI engineers, but your primary focus is translating AI capabilities into intuitive, production-ready user experiences.
What You'll Do Build and ship
LLM-powered chatbot and agent interfaces
using React and modern frontend frameworks Design and implement
streaming, event-driven UIs
for AI agents (token streaming, tool calls, agent states) Own frontend architecture for AI-first products, including reusable components and scalable UI patterns Integrate frontend applications with AI backends (LLMs, agent orchestration layers, RAG pipelines) Translate complex AI behaviors into clear, usable user experiences Optimize frontend performance, responsiveness, and reliability for real-time AI interactions Collaborate closely with product, design, and AI/backend engineers to iterate quickly Uphold high standards for code quality, maintainability, and testing in a fast-moving AI environment
What We're Looking For (Must-Have) 5+ years of professional frontend engineering experience Strong expertise in
React ,
Next.js , and modern TypeScript-based frontend stacks Hands-on experience building AI-powered UIs , especially: Chatbot or conversational interfaces LLM-integrated applications Streaming or real-time interfaces Experience integrating frontend with AI APIs (e.g. OpenAI, Anthropic, or similar) Solid understanding of frontend–backend interaction patterns in AI systems (state, latency, retries) Ability to independently take AI-driven features from concept to production Strong communication skills and product ownership mindset
Strongly Preferred Experience working with
AI agents , tool-calling flows, or multi-step LLM workflows Familiarity with
RAG-based UI patterns
(search, citations, context panels) Experience visualizing agent state, reasoning steps, or tool execution in the UI Built or shipped a production
LLM chatbot or copilot Experience in AI-first or fast-iteration product environments
Nice to Have Experience with .NET-based backends Familiarity with WebSockets, SSE, or streaming APIs Exposure to cloud platforms (AWS, GCP, Azure) Experience building internal tools or developer-facing AI products
