Full Stack Developer (RAG/LLM)

Jade Global; India; Remote; INR 1,800,000 - 3,000,000; Full time

Job summary

Jade Global is seeking a Full Stack Developer to build and scale web apps powered by large language models and retrieval-augmented generation. You will own end-to-end development from UI design to backend AI pipelines.

You will architect features with React/Next.js on the frontend and Python (FastAPI) or Node.js on the backend, connecting data via vector databases and enabling intelligent agent orchestration.

Qualifications

• 4+ years as a full-stack engineer with production RAG/LLM deployments.
• Strong front-end expertise in JavaScript/TypeScript, React.js, Next.js, and modern UI libraries.
• Backend proficiency in Python (FastAPI) or Node.js with PostgreSQL or MongoDB.
• Hands-on experience with LLM APIs, embeddings, and semantic search.
• Cloud/DevOps familiarity with Docker and CI/CD (GitHub Actions, Vercel, AWS/GCP).

Responsibilities

• Architect and deliver scalable web apps using React.js/Next.js frontend and Python/Node.js backend.
• Integrate LLMs via APIs and construct RAG pipelines with vector stores.
• Leverage LangChain/LlamaIndex for AI orchestration and prompt chains.
• Develop secure RESTful APIs and optimize performance for real-time features.
• Improve latency, implement caching, and manage deployment pipelines.

Job description

Role Overview We are seeking a Full Stack Developer to build, deploy, and scale web applications powered by Large Language Models (LLMs) and Retrieval-Augmented Generation (RAG). You will own the end-to-end development lifecycle, from designing responsive UIs to architecting robust backend AI pipelines.

Key Responsibilities

• Full-Stack Feature Delivery: Architect and develop scalable web applications using React.js/Next.js for the frontend and Python (FastAPI)/Node.js for the backend.
• LLM & RAG Integration: Design and implement RAG pipelines, connecting proprietary data to LLMs via vector databases (e.g., Pinecone, Qdrant, pgvector).
• AI Orchestration: Utilize frameworks like LangChain, LlamaIndex, or LangGraph to build intelligent agents and manage complex prompt chains.
• API Development: Build and maintain secure RESTful APIs to reliably serve AI model outputs and handle asynchronous user interactions.
• Performance Optimization: Optimize vector searches, reduce LLM response latency, and implement caching/streaming strategies for real-time generative features.

Required Qualifications

• Experience: 4+ years in full-stack software engineering, with actively building and deploying RAG/LLM applications in production.
• Frontend Mastery: Deep expertise in JavaScript/TypeScript, React.js, Next.js, and modern UI libraries (Tailwind CSS, Material UI).
• Backend & Infrastructure: Strong proficiency in Python (FastAPI) or Node.js, coupled with standard database management (PostgreSQL, MongoDB).
• AI/Data Stack: Proven hands-on experience with LLM APIs (OpenAI, Anthropic), open-source models (Hugging Face), vector embeddings, and semantic search.
• Cloud & DevOps: Familiarity with deploying containerized applications (Docker) and managing CI/CD pipelines via GitHub Actions, Vercel, or AWS/GCP.
