• Participate in model evaluation and validation, ensuring outputs meet quality, accuracy, and performance benchmarks
• Support testing and deployment of AI features through CI/CD pipelines using Azure DevOps
• Monitor AI feature performance in production using Azure Monitor and Application Insights
• Troubleshoot and refine AI behaviours in real-world production scenarios

Qualifications

• Hands-on experience working with large language models, particularly through Azure OpenAI Service (GPT models via Azure)
• Experience designing and integrating APIs and microservices on Microsoft Azure
• Familiarity with prompt engineering and LLM optimization techniques, ideally using Azure AI Studio or similar Microsoft tooling
• Understanding of model evaluation frameworks and performance metrics
• Experience working with ML Engineers or deploying ML models into production environments via Azure Machine Learning
• Knowledge of CI/CD pipelines and modern deployment practices using Azure DevOps
• Strong problem-solving skills and ability to work in a fast-paced, collaborative environment

Nice-to-Have
