Duties and Responsibilities

Background This position is located in the Decision-Support and Data Science Division (DSDSD). The Division is part of ESCWA's broader modernization and innovation efforts, providing advanced analytics and decision-support services within ESCWA, other UN entities, and Member States. Aligned with the UN 2.0 agenda and grounded in strategic foresight, DSDSD leverages data-driven insights, emerging technologies, and scenario-based planning to anticipate trends and proactively inform policymaking and operations. Its core functions span data integration, data quality assurance, advanced analytics and modeling, machine learning and AI solutions, real-time dashboards, performance reporting, and the design of specialized digital decision-support tools. Through these capabilities, DSDSD empowers evidence-based decision-making, fosters organizational efficiency, and catalyzes strategic innovation across the region. Work Assignment 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 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. 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. Research, Innovation, and Collaboration • Continuously monitor and evaluate emerging AI research, frameworks, and tooling to identify adoption opportunities aligned with DSDSD's mission. • Collaborate with data engineers, ML engineers, and domain experts to integrate AI capabilities into end-to-end data products. • Prepare technical reports, demonstrations, and presentations to communicate AI system design and findings to both technical and non-technical stakeholders.
