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.

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

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)
