• Build real-time views of files and artifacts generated by the AI.
• Connect the frontend with backend APIs and agent workflows.
• Leverage AI tools yourself to move faster (for prototyping, scaffolding, and UX exploration).

RESPONSIBILITIES

Frontend / UX

• Build a modern conversational interface in Next.js (App Router) with a chat panel, streaming AI responses, and message history.
• Implement a dynamic “artifact viewer” area (e.g., file tree, previews, details) that updates as the agent creates or modifies assets.
• Create responsive, multi-panel layouts that work well on desktop and mobile.
• Optimize rendering and state management for long-lived sessions and many messages.

• Implement infinite scrolling / pagination patterns where needed (e.g., history, lists).

   

  Backend

• Strong backend engineering experience (Node.js + TypeScript preferred)
• Solid API design and implementation (REST/GraphQL), validation, and versioning
• Real-time/streaming delivery (SSE / WebSockets / fetch streaming)
• Data modeling + persistence (Postgres/SQL and/or NoSQL), migrations, indexing
• Async workflows: queues/jobs, retries, idempotency (SQS/RabbitMQ/Kafka/BullMQ or similar)
• Auth & security basics (OAuth/JWT, RBAC, secrets)
• Production readiness: logging/metrics/tracing, performance, debugging
• Comfortable using Next.js server features (Route Handlers/API routes) as the integration layer
   

Full-Stack Integration

• Implement and consume API routes for:
  • Sending messages to the agent.
  • Fetching and updating project artifacts.
  • Managing project/session state on the client.
• Integrate the frontend with backend agentic flows (tool calls, file operations, external system integrations).
• Apply sensible caching and revalidation strategies (ISR/ISG, SWR, edge caching) to reduce backend load while keeping data fresh.
• Collaborate with backend engineers on data contracts, tool schemas, and event formats.
   

AI-Assisted Development

• Use AI tools (such as Lovable, Base44, Bolt.new, model-based coding assistants, etc.) for:
  • Rapid UI prototyping.
  • Generating boilerplate.
  • Exploring UX and flow ideas.
• Be comfortable iterating quickly on product and UX based on feedback.
   

REQUIRED SKILLS

• Strong experience with Next.js (preferably App Router) and modern React.
• Experience building interactive UIs such as chat interfaces, dashboards, or IDE-like tools.
• Familiarity with:
  • Streaming responses (SSE, fetch streams, or similar).
  • State management patterns in React.
  • Basic web performance and rendering optimization.
• Experience integrating frontend code with backend APIs.
• Comfortable using AI tools to accelerate development rather than resisting them.
• Experience building conversational AI interfaces, copilots, or agent-based products.
• Exposure to LLM concepts such as function calling (tools), RAG, or vector search.
• Experience with Tailwind, component libraries, or design systems.
• Experience working with developer tools or “builder” style products.
