Job Description

AI Engineer

Job Summary

The AI Engineer is responsible for designing, building, evaluating, and optimizing AI-driven systems with a strong focus on large language models (LLMs). This role requires hands-on experience in AI evaluations, prompt optimization, Retrieval-Augmented Generation (RAG) pipelines, and autonomous agent architectures, ensuring scalable, reliable, and high-performance AI solutions in production environments.

Key Responsibilities

AI System Design & Development

  • Design, implement, and maintain AI-powered applications using large language models.
  • Build and optimize Retrieval-Augmented Generation (RAG) pipelines for accurate, grounded responses.
  • Develop autonomous agents and multi-agent systems to solve complex workflows and tasks.

Prompt Engineering & Optimization

  • Design, test, and systematically optimize prompts to improve model performance and reliability.
  • Establish prompt iteration frameworks using quantitative and qualitative evaluation methods.
  • Implement strategies to handle large context windows while minimizing context degradation and memory loss.

Evaluation & Performance Monitoring

  • Set up and maintain AI evaluation (Evals) frameworks to measure model quality, accuracy, and consistency.
  • Define evaluation metrics and automated testing pipelines for continuous improvement.
  • Analyze model outputs and iterate based on performance insights.

Infrastructure & Reliability

  • Handle rate limits, streaming responses, retries, and error handling in production systems.
  • Implement logging, monitoring, and fallback mechanisms for robust AI services.
  • Optimize latency, cost, and throughput of AI model usage.

Collaboration & Best Practices

  • Work closely with software engineers, data teams, and product stakeholders to integrate AI solutions.
  • Stay current with emerging AI tools, frameworks, and best practices.
  • Contribute to internal documentation, standards, and reusable AI components.

Required Qualifications (Updated)

  • Bachelor's or Master's degree in Computer Science, Artificial Intelligence, Data Science, or a related field.
  • Proven experience building and deploying LLM-based systems in real-world applications.
  • Hands-on experience with prompt engineering, AI evaluation (Evals), and systematic prompt optimization workflows.
  • Experience with Azure AI Foundry or similar cloud-based AI platforms (e.g., AWS, GCP).
  • Experience in fine-tuning, deploying, and maintaining custom Large Language Models (LLMs).
  • Hands-on experience working with Arabic-language trained language models and Arabic text processing.

Technical Skills

  • Strong experience designing and implementing RAG pipelines (vector databases, embeddings, retrieval strategies).
  • Experience building autonomous agents and multi-agent systems.
  • Deep understanding of prompt optimization techniques and evaluation methodologies.
  • Proficiency in handling large context windows, memory management, and context-compression strategies.
  • Experience managing API rate limits, streaming responses, retries, and error handling.
  • Proficiency in Python and modern AI/ML tooling.

Preferred Skills

  • Experience with vector databases (e.g., FAISS, Pinecone, Weaviate, or similar).
  • Familiarity with orchestration frameworks for agents and workflows.
  • Experience deploying AI systems in cloud or production environments.
  • Understanding of AI safety, reliability, and responsible AI practices.

Key Competencies

  • Strong problem-solving and analytical skills
  • Systematic experimentation and evaluation mindset
  • Ability to translate business needs into AI solutions
  • Attention to reliability, scalability, and performance
