• Build Generative AI features for enterprise applications, including text generation, summarization, and RAG-based intelligent assistants
• Design and orchestrate multi-agent AI systems that automate complex workflows and decision-making
• Design, train, and deploy machine learning models to solve classification, regression, NLP, and other business problems
• Own AI pipelines end-to-end, from data ingestion through model inference and serving
• Evaluate and monitor model and agent performance in production, iterating based on results
• Write clean, scalable, production-ready code and maintain source control and CI/CD workflows
• Partner with cross-functional teams in an Agile/Scrum environment to ship AI capabilities
