• Support model lifecycle management, including monitoring, retraining, and performance optimization
• Implement MLOps best practices for version control, CI/CD, and automated deployment
• Assist in the development of advanced analytics dashboards and tools to communicate model results
• Apply prompt engineering, retrieval-augmented generation (RAG), and fine-tuning to build effective large language model (LLM) solutions
• Build and integrate LLM-powered agents to automate multi-step tasks and workflows that complement traditional ML models
• Ensure responsible AI practices, including fairness, transparency, and compliance
• Gather, clean, and analyze large and complex datasets to support AI initiatives
• Conduct experiments and statistical analyses to answer business questions and validate AI models
• Stay current with emerging AI technologies and recommend innovative solutions

skills/qualifications required:

• Experience in data cleaning, exploration, and analysis
• Hands-on experience with machine learning and deep learning frameworks (e.g., TensorFlow, PyTorch, Scikit-learn)
• Proficiency in Python and SQL for data manipulation, analysis, and model development
• Familiarity with cloud platforms (Azure/Fabric, AWS, or GCP) for scalable AI/ML deployment
• Experience with MLOps tools and practices (e.g., MLflow, Kubeflow, CI/CD pipelines)
• Experience applying large language models (LLMs), including prompt engineering and fine-tuning, and responsible AI practices
• Ability to visualize data and model results using tools like Power BI, Tableau, Matplotlib, or Seaborn
• Strong communication skills for collaborating with business and technical teams
• Exposure to building AI agents or agentic workflows (e.g., LangChain, LangGraph) a plus
• Experience in manufacturing and supply chain (preferred)
