Senior AI Engineer (Full-Stack)

Experience Required - 4 - 6 Years

Location - Ahmedabad (Onsite)

About the Role

We are hiring a Senior AI Engineer who builds production-grade AI products end-to-end. You will design and ship AI agents, Retrieval-Augmented Generation (RAG) systems, and fine-tuned small language models, while also owning the full-stack delivery from React/Vue/Angular frontends through Python/Node backends to AWS, GCP and Azure deployments.

Equally significant: you are an AI-adopted engineer. You use Claude Code, Cursor, Codex, and other AI coding assistants as a daily multiplier, and you know how to use them well — managing context, controlling token spend, writing CLAUDE.md / AGENTS.md files, using subagents and MCP servers, and applying evaluation-driven workflows so that AI-generated code is shipped responsibly.

What You Will Do
- Design, build and deploy AI agents using LangChain, LangGraph, LlamaIndex, CrewAI or equivalent frameworks — including multi-agent orchestration, tool use, memory, and planning loops.
- Architect RAG pipelines end-to-end: ingestion,



chunking, embedding selection, vector stores (Pinecone / Weaviate / Qdrant / pgvector), hybrid search, re-ranking, query rewriting, and evaluation.
- Fine-tune small and open-source language models (Llama, Mistral, Phi, Gemma, Qwen) using LoRA, QLoRA, PEFT, instruction tuning and DPO — and decide when fine-tuning is the right answer versus prompting or RAG.
- Build full-stack AI applications: React/Next.js frontends with streaming UIs (Vercel AI SDK / SSE / WebSockets), FastAPI or Node backends, and well-designed APIs.
- Own deployment, scaling and observability on AWS (Bedrock, SageMaker, Lambda, ECS/EKS) and GCP (Vertex AI, Cloud Run, GKE), with Docker, Kubernetes, Terraform and CI/CD.
- Implement LLM observability and evals using LangSmith, Langfuse, RAGAS, DeepEval — and treat evaluation as a first-class engineering artifact, not an afterthought.
- Apply AI coding assistants (Claude Code
