AI Agent / LLM Engineer

About us
Raushang4 Technology builds custom AI agents, full-stack products and headless e-commerce for Indian D2C brands, plus Salesforce, IoT and mobile work. We're an early-stage, founder-led company. Custom AI agents are the core of what we do, and you'll work directly with the founder, Raushan Kumar (Full Stack & Agentic AI Architect).

What you'll do

• Build production agents for D2C support and operations: tools, guardrails, retrieval and evals. Not a demo chatbot.
• Build agents that do real work: answering customers on WhatsApp, tracking orders, recommending products and automating ops.
• Design the agent architecture and connect tools and data (Shopify, CRMs, catalogues).
• Prove quality with evals before anything goes live, and watch reliability and cost as closely as the prompts.

Must-have skills

• LLM APIs and tool/function calling
• RAG or evals on a real project
• Python or TypeScript
• Clear written architecture (we ask for your GitHub profile when you apply)

Nice to have

• RAG depth: chunking, embeddings, vector DBs (pgvector/Pinecone/Qdrant)
• Agent orchestration (LangGraph, LlamaIndex, Vercel AI SDK or custom)
• Guardrails, hallucination checks, cost and latency tracking
• Integrations with Shopify, WhatsApp, CRMs and helpdesks
• Hindi/Hinglish prompt handling
• Observability (Langfuse/LangSmith or similar)
