Job Description

UltaHost is building UltaBuilder AI, a next-generation website and application builder powered by artificial intelligence. We're hiring a Full Stack AI-Driven Web Platform Engineer to help develop the interactive web builder interface, integrate AI-generated output, and connect user prompts to real-time code previews. This role blends frontend engineering, backend logic, and AI integration to create a seamless, intelligent website-building experience. You’ll work with AI architects, prompt engineers, and UI/UX teams to deliver a product that transforms how users build online platforms.

Job Responsibility

  • Build and maintain the frontend builder interface using React and TailwindCSS
  • Integrate LLM APIs (OpenAI, Claude, Mistral) to process prompts and return structured layout/code
  • Develop backend APIs and logic for code rendering, preview sessions, and project saving
  • Handle dynamic component rendering in real-time using iframe, srcDoc, or virtual DOM
  • Create middleware for post-processing and validating AI-generated code
  • Work with Prompt Engineers to build stable prompt-to-code pipelines
  • Connect user input to modular component libraries with proper formatting and behavior
  • Build user session handling, autosave, and rollback infrastructure
  • Ensure the platform is responsive, fast, and intuitive on both desktop and mobile
  • Deploy backend services using scalable infrastructure (e.g., Vercel, Docker, or custom VPS setup)

Requirements

  • 4+ years of experience in full stack web development
  • Strong expertise in React, TailwindCSS, and component-based UI architecture
  • Solid experience in backend development using Node.js (or Go/Python)
  • Experience working with OpenAI/LLM APIs or building AI-powered workflows
  • Familiarity with dynamic rendering, live preview architecture, and iframe usage
  • Understanding of state management (Redux, Zustand, etc.)
  • Knowledge of prompt-to-code architecture and API validation logic
  • Experience with Git-based version control and deployment pipelines
  • Strong problem-solving skills and attention to performance optimization

Nice to have

  • Experience building website builders, CMS platforms, or visual editors
  • Familiarity with JSON-to-UI generation systems or low-code tools
  • Exposure to LangChain, PromptLayer, or similar LLM chain libraries
  • Experience in SSR/ISR frameworks like Next.js
  • Knowledge of WebSocket or socket.io for real-time updates
  • Understanding of AI safety layers and model output filtering

What we offer

  • Competitive salary, bonuses, and token/equity opportunities
  • Full remote flexibility
  • High-impact role in a flagship AI product
  • Access to premium AI model APIs and infrastructure
  • Fast-paced, builder-focused environment with creative control
