AI Summary
Designs, develops, and deploys production-grade AI solutions using LLMs and VLMs, building RAG pipelines, multimodal systems, and AI agents while optimizing inference and collaborating with cross-functional teams.
About this role
Role Overview
We are looking for an AI Engineer specializing in Large Language Models (LLMs) and Vision-Language Models (VLMs) to design, develop, and deploy production-grade AI solutions. The ideal candidate should have strong experience with LLM/VLM architectures, prompt engineering, RAG, fine-tuning, multimodal AI, and model serving.
Key Responsibilities
- Develop and deploy AI applications using LLMs and VLMs.
- Build RAG pipelines involving document ingestion, chunking, embeddings, retrieval, reranking, and generation.
- Work with models such as GPT, Claude, Gemini, Llama, Mistral, Qwen, and multimodal/VLM models.
- Develop multimodal solutions involving text, images, PDFs, charts, tables, and documents.
- Perform prompt engineering, supervised fine-tuning, LoRA/QLoRA, and model evaluation.
- Build AI agents and tool-calling workflows where appropriate.
- Optimize inference for latency, throughput, memory, and cost.
- Develop APIs and production services using Python, FastAPI, Docker, and cloud platforms.
- Implement evaluation frameworks to measure accuracy, hallucination, relevance, latency, and safety.
- Collaborate with ML engineers, software engineers, and product teams to take prototypes into production.
Required Skills
- Strong Python programming and software-engineering fundamentals.
- Hands-on experience with LLMs and/or VLMs.
- Strong understanding of Transformers, attention mechanisms, tokenization, embeddings, and inference.
- Experience with PyTorch and Hugging Face Transformers.
- Experience building RAG systems and vector-search solutions.
- Knowledge of prompt engineering and LLM evaluation.
- Experience with APIs, REST services, Git, Docker, and CI/CD.
- Familiarity with vector databases such as FAISS, Milvus, Pinecone, Weaviate, or pgvector.
- Understanding of cloud AI infrastructure, preferably AWS/Azure/GCP.
VLM / Computer Vision Skills
- Experience with multimodal models such as Qwen-VL, LLaVA, Gemini, GPT vision models, or similar.
- Understanding of image preprocessing and document/image understanding.
- Experience with OCR, document intelligence, image classification, object detection, or visual question answering is a plus.
- Ability to build pipelines combining vision + language + retrieval.
