Lead AI Engineer

• Architect and build GenAI and agentic AI solutions: multi-agent workflows, tool calling, memory and human-in-the-loop.
• Design, optimise and evaluate RAG pipelines and vector search for accurate, grounded answers.
• Fine-tune and adapt LLMs and other foundation models for domain-specific tasks.
• Build and deploy deep learning, NLP and computer vision models for prediction, classification and automation.
• Evaluate AI systems and optimise them for quality, cost and latency.
• Implement guardrails, security and responsible-AI practices (bias, privacy, hallucination and prompt-injection controls).
• Lead and mentor AI engineers, review code and designs, and partner with product and business teams on use cases and success metrics.

Required skills

• Programming: Expert Python (NumPy, Pandas, FastAPI, async); SQL.
• Generative AI and LLMs: OpenAI, Anthropic Claude, Gemini, Llama and Mistral; prompt engineering, structured outputs and function calling.
• Agentic AI: LangChain, LangGraph, LlamaIndex, CrewAI or AutoGen; MCP (Model Context Protocol) and tool integrations.
• RAG and vector databases: Chunking, embeddings, hybrid search and re-ranking; Pinecone, Weaviate, Qdrant, Milvus, Chroma, FAISS or pgvector.
• Fine-tuning: Hugging Face Transformers, LoRA/QLoRA, PEFT and RLHF/DPO basics.
• Deep learning: PyTorch and TensorFlow/Keras; CNNs, RNNs and Transformers.
• NLP and computer vision: Text classification, NER, summarisation; OpenCV, YOLO and vision-language models.
• Evaluation and responsible AI: Ragas or DeepEval, guardrails, bias and safety testing.
• Cloud: AWS (SageMaker, Bedrock), Azure (Azure OpenAI, Azure ML) or GCP (Vertex AI).
  • Education: Bachelor's or Master's in Computer Science, AI, Data Science or a related field.
