Responsibilities

• The Consultant will be responsible for the following tasks: 1
• Agentic AI System Design and Development Architect and implement multi-agent systems using frameworks such as LangGraph, AutoGen, CrewAI, or equivalent, capable of orchestrating complex reasoning, retrieval, and action pipelines
• Design and deploy Retrieval-Augmented Generation (RAG) systems with advanced retrieval strategies (hybrid search, re-ranking, contextual compression) for knowledge-intensive tasks
• Implement tool-use, MCPs, and function-calling patterns enabling agents to interact with external APIs, databases, and computational tools
• Develop agent evaluation frameworks, including automated benchmarking, failure analysis, and iterative improvement loops
• Basic understanding of Agent Based Modeling (ABM) development and frameworks 2
• LLM Integration and Optimization Integrate and benchmark state-of-the-art LLMs (proprietary and open source) across use cases including information extraction, summarization, classification, and question answering on Arabic and multilingual content
• Apply prompt engineering, structured output generation, and chain-of-thought techniques to maximize model reliability and task performance
• Explore and implement fine-tuning strategies (LoRA, QLoRA, full fine-tuning) where domain adaptation is required
• Monitor and optimize inference costs, latency, and throughput for production deployments. 3
• AI Infrastructure and API Development Design and implement RESTful and streaming APIs to expose AI capabilities to internal systems and the ADP platform
• Containerize AI services using Docker and manage deployments in line with organizational infrastructure standards
• Maintain documentation, versioning, and model cards for all deployed AI systems. 4
