AI Engineer Intern

About the role

infinall.ai is hiring an AI Engineer Intern for a 6-month paid, on-site internship in LB Nagar, Hyderabad. You will work directly on the live product that generates complete marketing campaigns and advertisements using AI. This is a real engineering role where your code will be used by actual users, rather than a shadowing internship. About the Company: OriMind builds infinall.ai, an AI platform that takes a company's website URL, understands what the product does, and creates a complete marketing campaign including research, strategy, copy, and image/video advertisements. The product is live with real users and is being built by a small team in Hyderabad. The Role: You will work on the part of the product responsible for creating advertisements. The system understands what users request, generates the output, and allows users to modify it through natural-language instructions. What You Will Work On: * Work on the AI agents behind ad generation that understand user requests, plan advertisements, build them, and verify the output. * Make the planning step faster and smarter so generated results better match user requirements. * Improve knowledge-base search by working with document splitting, PostgreSQL, pgvector, and retrieval quality. * Build the chat editing feature that converts natural-language instructions into actual changes in advertisements. * Treat prompts like production code by maintaining version control, writing tests, and validating quality before deployment. * Ensure generated advertisements remain accurate to the customer's brand and do not make unsupported claims. * Help run backend FastAPI services and background jobs on AWS. * Improve generation speed and reduce infrastructure and model costs without compromising output quality. What We Are Looking For: * Python as a core programming language. * FastAPI for asynchronous backend services and streaming. * LLM development experience or strong interest in building production LLM systems. * LangChain / LangGraph for agent orchestration. * Multi-agent architecture and planning systems. * RAG and retrieval pipelines. * PostgreSQL and pgvector for vector storage and retrieval. * AWS services including RDS, S3, and compute. Nice to Have: * Exposure to marketing, advertisements, campaigns, content, or social media. * Experience with image or video generation models. * Experience writing tests or evaluation/scoring systems for AI output. * Understanding of AI system cost and performance optimization. What You Get: * Paid internship for the full six months. * Real ownership of a part of the product. * Direct access to the founder and engineering team. * Opportunity for a full-time offer based on performance and mutual fit. * Opportunity to work on a live AI product with real users. Tech Stack: Python, FastAPI, LangChain, LangGraph, PostgreSQL, pgvector, AWS, LLM Gateway. How to Apply: Send your application to hr@infinall.ai with your resume as a PDF and a link to something you have built with LLMs, such as GitHub, a live project, college project, or short write-up. If you have not built much yet but learn quickly and genuinely want to work on this, you can still apply and explain why.
