AI Engineer Intern

About the job

Role Description This is a full-time on-site role, located in Coimbatore. As an AI Engineer Intern at Cobay, you will help design and ship AI-powered features on top of our existing products, working across backend services, simple UIs, and LLM/RAG workflows. You’ll collaborate with engineers and product owners to turn real business use-cases into small, production-ready AI tools, from integrating model APIs and retrieval pipelines to wiring them into our internal and customer-facing applications. Qualifications • Final-year or recent graduate in Computer Science / IT / AI / Data Science or related field, with solid programming fundamentals. • Strong skills in Python plus working knowledge of JavaScript/TypeScript or any modern web stack. • Understanding of LLM and RAG basics: embeddings, vector stores, retrieval, context window limits, and prompt design. • Hands‑on experience (projects / internships / hackathons) building at least one LLM-based application such as a chatbot, Q&A bot, or AI assistant. • Familiarity with one or more orchestration frameworks like LangChain, LlamaIndex, or similar tooling is highly preferred. • Exposure to vector databases / search systems (FAISS, Chroma, Pinecone, Elasticsearch-vector, etc.). • Ability to work with REST APIs, JSON, Git, and basic cloud or deployment workflows (any provider). • Any prior work with AI agents, workflow builders, or automation around LLMs. Key responsibilities • Design and implement end‑to‑end AI-driven features such as smart assistants, intelligent search, and workflow automation for our existing platforms. • Build and refine RAG-style pipelines: document ingestion, chunking, embeddings, vector search, and context assembly to provide accurate, contextual responses from domain data. • Integrate LLM and GenAI APIs into backend services and microservices, exposing them via clean, well-documented REST endpoints. • Work with the full stack team to connect these services to simple, usable UIs (dashboards, chat interfaces, internal tools) and ensure smooth user experience. • Monitor behaviour of AI features, log edge cases, and iterate on prompts, retrieval logic, and guardrails to improve reliability. • Collaborate with product and business stakeholders to understand use‑cases and translate them into small, shippable AI features.
