UltaHost is building UltaBuilder AI, an advanced AI-powered website and application builder. We are hiring a Prompt-to-Code Systems Architect to lead the design of infrastructure that converts user prompts into structured, functional frontend and backend code. You’ll build the underlying engine that drives our AI web builder, enabling users to go from idea to website in seconds. This role blends prompt engineering, LLM pipelines, code generation, and backend system design. You’ll work closely with prompt engineers, frontend developers, and AI researchers to build a scalable, intelligent system that delivers clean, modular code output.
Job Responsibility:
Architect the full pipeline that converts text prompts into HTML/CSS/JS or React components
Design logic for interpreting natural language into structured layout and behavior trees
Build integrations with LLMs (GPT, Claude, Mistral) to generate frontend and backend code
Develop middleware to parse, validate, and modularize AI-generated code
Create safety checks and formatting layers to ensure clean output
Implement smart component mapping logic (e.g., convert “add a contact form” into code)
Work with frontend teams to integrate generated code directly into a live preview or editor
Lead versioning, rollback, and session management for user projects
Optimize performance of real-time AI generation and delivery
Guide overall architecture to ensure scalability, modularity, and future model upgrades
Requirements:
5+ years of experience in system architecture or full-stack development
Strong experience with LLM APIs (OpenAI, Anthropic, or open-source models)
Deep understanding of frontend frameworks (React, Next.js, Vue)
Backend experience with Node.js or Go, including API architecture
Proficiency in prompt engineering and dynamic input-to-output transformations
Familiarity with AST parsing, codemods, or token-based code manipulation
Experience designing multi-step pipelines with validation and rollback
Strong understanding of web component structures and UI rendering logic
Excellent communication and system documentation skills
Nice to have:
Experience with LangChain, LlamaIndex, or custom RAG frameworks
Familiarity with visual programming or low-code builders (e.g., Builder.io, Webflow Logic)
Past experience with AI agents that generate or refactor code
Knowledge of JSON-to-UI generation pipelines
Understanding of database schema generation from prompts
Familiarity with Git-based version control APIs (for AI-generated projects)
What we offer:
Competitive salary with bonuses and equity/token options
Full ownership of your architectural roadmap
Flexible remote work
Work with top-tier AI tools and GPU infrastructure
Opportunity to lead a flagship UltaHost product used by creators worldwide
