Job Description

The role involves various responsibilities in the field of AI engineering, focusing on prompt engineering, API integration, model fine-tuning, data engineering, LangChain/LlamaIndex development, vector databases, and frontend + GenAI integration. You will be responsible for crafting effective prompts for models like GPT DALLE and Codex, along with understanding prompt tuning chaining and context management. Additionally, you will work on API integration, utilizing APIs from platforms such as OpenAI, Hugging Face, and Cohere. This will involve handling authentication, rate limits, and response parsing effectively. Furthermore, you will be involved in model fine-tuning and customization, working with open-source models like LLaMA, Mistral, and Falcon. Tools such as LoRA, PEFT, and Hugging Face Transformers will be utilized in this process. In the realm of data engineering for AI, you will focus on collecting, cleaning, and preparing datasets for training or inference purposes. A good understanding of tokenization and embeddings will be crucial in this aspect. You will also work on LangChain/LlamaIndex, where you will build AI-powered applications with memory tools and retrieval-augmented generation (RAG). This will involve connecting large language models (LLMs) to external data sources like PDFs, databases, or APIs. Additionally, you will work with vector databases such as Pinecone, Weaviate, FAISS, or Chroma for semantic search and RAG, requiring a solid grasp of embeddings and similarity search techniques. Another aspect of the role involves frontend and GenAI integration, where you will build GenAI-powered user interfaces using technologies like React, Next.js, or Flutter. Integration of chatbots, image generators, or code assistants will also be part of this responsibility. Overall, the role encompasses a diverse set of tasks in AI engineering, ranging from prompt engineering and model fine-tuning to data engineering and frontend development, all aimed at creating innovative AI solutions.,
