  • Experience choosing/training models (LLMs/transformers) and deploying safely with monitoring/observability
  • Hands-on experience in fine-tuning LLMs, Agentic AI, MCPs and RAG systems
  • 2+ years of experience in AI/ML engineering, with a focus on NLP, LLMs, and conversational AI
  • Strong experience with Python and knowledge of JavaScript development (TypeScript, React)
